INTRODUCTION OFFSHORE CABLES In this catalogue General Cable presents its series of shipboard energy, control and instrumentation cables for fixed installations on vessels and oil rigs. The safety of people and equipment is a priority consideration in the design and construction of Exzhellent-606 and Genfire-606 cables. They are made from zero-halogen compounds with a low-acidity and -corrosivity of gases evolved and a low opacity of fumes evolved during combustion, in accordance with the corresponding IEC standards. They therefore allow for quick, safe evacuation in the event of fire. The cables are designed to comply with the strictest non-fire propagation standards and prevent the generation of secondary seats of fire even in circumstances of high cable concentration in unfavourable conditions. There are also fire-resistant designs that feature not only the above properties, but are also able to continue providing service even when directly affected by fire. Their use in safety services enables the services to continue working even in situations of fire. Reinforced cables feature standard tinned copper braiding that provides good mechanical protection and may also be used in specific applications such as shielding. Exzhellent-606 and Genfire-606 cables may be used in extreme climates, principally because of their resistance to very low temperatures. This catalogue also includes specific designs for energy cables used in circuits with variable frequency drives (VFD). The cables described in this catalogue have been designed in accordance with the following standards and specifications.

Individual and/or collective screening of units using Cu / Poliester tape and drain wire. Cable screening using tinned copper wire braid. CONSTRUCTION On the basis of the above-mentioned IEC standards, and reviewing the formation of the cables, we have: Conductor Tinned annealed copper in accordance with IEC 60092-350: Class 2: Rigid conductors with 7 wire formation (in small sections) or concentric layers in big cross sections. Class 5: Flexible conductors bunched or multibunched configurations. In general those class 2 are used, but the use of class 5 is growing, due to their handeability and therefore their greater ease of installation. 11
Tin plated conductor is used to offer greater protection of conections against oxidation in heavy marine environments. See the following tables for standarized sections and compositions to be used: CROSS SECTIONAL AREA Cable type Voltage (kv) Area of conductor (mm 2 ) IEC Standard Power Low Voltage 1 kv 3 kv 1,5 : 300 mm 2 10 : 300 mm 2 60092-353 Instrumentation 250 V 0,50 : 2,50 60092-376 Power Medium Voltage 6 kv 10 kv 15 kv 20 kv 10 : 630 mm 2 16 : 630 mm 2 25 : 630 mm 2 35 : 630 mm 2 60092-354 COMPOSITION NUMBER OF CORES Cable type Number of cores IEC Standard Power L.V.

Insulation materials NEK TS 606 specifies insulation materials making reference to standard IEC 60092-351. The ones used in the current catalog are: EPR (Ethylene propylene). A thermosetting elastomer, it has an almost nil distortion due to the action of heat. It gives the cable greater flexibility. Especially suitable if the sheath has to be a crosslinked compound. HEPR (Hard grade etylene propylene). Improved EPR compound bringing beter performance both in mechanical o electrical properties. This brings to a thickness insulations similars to the XLPE ones. INSULATION MATERIALS Maximum rated conductor Temperature ºC T ype of insulating compound Abbreviated designation Normal Operation Short-circuit Elastomeric or thermoset Ethylene-propylene rubber or similar (EPM o EPDM) Halogen free EPR 90 250 High modulus of hard grade halogen free ethylene propylene rubber HEPR 90 250 Sheating materials The sheath of the cables protects the set of cores from the mechanical or environmental aggressions they can suffer. Mechanical aggressions are mainly abrasions from the dragging of the cables and tears at angles of the tubes and occur during the installation, while the environment aggressions (heat, presence of oils or aggressive agents) will affect the cable throughout its working life. Halogen free termosetting compound SHF 2. It has the advantages of being a heat-stable compound which does not release toxic gases or opaques smoke in case of fire (see annex 2), and it has good resistance to oils, fuel and solvents. Good resistance to mechanical demands. 13
Halogen-free mud-resistant crosslinked compound SHF Mud. The same characteristics as per material type SHF 2 adding mud resistance according to NEK TS 606. Type of sheathing compound Abbreviated designation Elastomeric or thermoset Ethylene-propylene rubber or similar (EPM o EPDM) Halogen free SHF 2 High modulus of hard grade halogen free ethylene propylene rubber SHF Mud Armouring The armour gives the cable mechanical protection. The copper in tinplated version being used in this case. The use of tinned copper in the armour performs a dual function as it behaves as armour but also as a screen. Type Materials BRAID Tinned annealed copper Screening In low tensión cables, the screens are the elements which provide the cable protection against electromagnetic fields. This is an element especially suitable for cables for instrumentation, control and transmission of signals thanks to its sensitivity to radiation which can distort the signal transmitted by the cable. To protect the cable from radiation it is necessary to screen the group of conductors (protection from external disturbance) or each one of the pairs or triples (electromagnetic fields from other elements of the same cable). According to the standard, screens can be either braid or laminated polyester tape. In all designs of 2, 3 and 4 cores, the screen cross-section has been defined according to the criteria set in standard IEC 60092-352 Table 2, so it can be used as an earthing conductor. In armoured type cables, the use of tinned copper wire braid armour, when properly earthed, allows to use it as a collective screen. Type Materials BRAID TAPE Tinned annealed copper Cu / Polyester 14
Electromagnetic compatibility (EMC) When General Cable products are installed in accordance with IEC 60533, they fulfil the requirements for Electro-Magnetic Compatibility. FIRE PERFORMANCE OF CABLES To establish how cables perform in the event of fire, a series of standards have been developed to define fire conditions and measure the cable s performance in a similar situation to that of the installation. It should nonetheless be remembered that these tests establish fixed, reproducible conditions used to appraise the performance of the cables in this situation. Current IEC standards envisage the following events: Flame retardant (IEC 60332-1-2) A 1 kw flame in contact with the cable sheath for a time established in the standard should not spread. The cable will not therefore prompt a fire caused by a minor incident or by an external heat source with which it comes into accidental contact. Flame retardant (IEC 60332-3-22) A fire unconnected with the cable may affect a wiring system and become more serious if the system is oriented vertically, thus allowing the circulation of air and the creation of a chimney effect. If the decomposition temperature of the organic materials is reached, exothermic combustion of the cables occurs and the fire spreads. The insulation compounds used in Exzhellent-606 y Genfire-606 cable sheaths are designed to hinder exothermic reaction. To simulate this situation, the test involves the application of powered air and a 20-kW gas burner to a bundle of cables arranged to simulate a vertical wiring system. In these conditions, a fire in the cables prolonged for 40 must go out in the time established in the standard and must not exceed a length of 2.5 metres. The prescribed standard applicable in the ship industry is IEC 60332, part. 3-22, cat A. Category A prescribes the maximum volume of inflammable material (seven litres per metre). Fire resistance (IEC 60331) IEC 60331 defines the test conditions applied to a cable that must remain in service in safety circuits even when directly affected by a fire and when its organic parts are decomposing. IEC 60332-1 15
In the test, the cable is subject to the action of a burner at a minimum flame temperature of 750 ºC (standard IEC 60331-21) or of 830 ºC (for cables with an overall diameter of over 20 mm in IEC 60331-1 and for cables with an overall diameter not exceeding 20 mm in IEC 60331-2) for a period of 90 minutes, during and at the end of which the cable must remain in service. Halogen-free and low smoke emission cables Cables subject to fire, depending on the materials of which they are made, may give off gases that are toxic for people s health or corrosive and therefore hinder the proper operation and preservation of the electronic and IT components in the vicinity. Opaque smoke that prevents a view of the escape routes from the affected sites may also be given off. To minimise these effects, General Cable has developed the Exzhellent series cables that eliminate harmful emissions of halogenated and toxic gases (IEC 60754-1 and 60754-2), substantially reduce opaque smokes and thus facilitate the evacuation of people (IEC 61034-2).

TECHNICAL INFORMATION CABLE DESIGNATION Cable designation is based in the letter code described in the tables below: Halogen free design Materials Insulation Inner covering / Inner Sheath Armour / Shield Outer Sheath Additional characteristics Fire resistant tape + insulation B Ethylene Propylene Rubber (EPR) R Inner covering F No armour X Tinned Copper wire braid O Thermoset compound SHF 2 or SHF Mud U Unit screening (i) Individual (c) Collective Variable frequency drives VFD The cable designation also includes the number and size of cores (NxS), substituing the symbol x by the symbol G when an earth core is required. In two, three or four core cables armoured power, the NxS/E terminology is used to illustrate the cables in wich the copper wire braid armour can be employed as the earth conductor. In this case, the cross sectional area of the braid (E) is equal or greater than 50% of the phase conductors. CURRENT CARRYING CAPACITIES General Cable recommends the utilisation of current ratings according to standard IEC 61892-4 based on conductor temperature of 90 ºC and ambient temperature of 45 ºC. As an alternative, it is possible to use the current ratings included in the regulations of third-party bodies. De-rating factors for differing methods of installation, and ambient temperatures are specified in IEC 61892-4. 19

INSTALLATION GUIDE 1. INTRODUCTION This manual provides installation methods commonly encountered in naval and offshore applications and should be used in conjunction with the engineer s installation specifications and all applicable codes. These methods are recommended for all types of power, control and instrumentation cables. This manual is intended for use by the design engineer and the installer in the field and is not a text on power system design or electrical circuit analysis. The information provided is concise and should be adequate for the majority of installations. If you require additional information, please contact General Cable at info@generalcable.es. In this document are described the rules and procedures to take into account during handling of electrical cables, with especial attention given to the characteristics of the cable to assure adequate transportation, laying and connection. The laying procedure is delicate and the cables must be handled and installed properly to avoid damages. Significant damages may be caused by improper handling of cables, which either are detected when voltage is applied or will cause a reduction of cable quality, with resulting reduction of cable life. 2. PRE-INSTALLATION To ensure safety during cable installation and reliability once the cable is installed, you should confirm the following prior to installation: The cable selected is proper for your application. The cable has not been damaged in transit or storage. Review all applicable project, regional and specific rules, regulations and codes to verify that the cable selected is appropriate for the installation job. In case of classification / certification bodies, also consult them. Any existing cable damage must be identified and any further damage prevented from occurring. This is done through proper cable inspection, handling and storage. 2.1 Transportation The cable drums shall always be transported in up-right position and never laying on its flanges. They shall be properly fix in order to avoid uncontrolled displacements and eventual falls on their sides. 72
2.2 Cable handling YES NO Remove all nails and staples from the reel flanges before moving a reel, and avoid all objects that could crush, gouge or impact the cable while it is being moved. NEVER use the cable as a means to move a reel. When unreeling, observe recommended bending radii, use swivels to prevent twisting, and avoid overruns. 2.3 Cable storage Cables should be stored on hard surfaces so that reel flanges cannot sink. Small reels may weigh several hundred kilos while large reels can exceed several tons. 73
As much as possible, outside storage shall be avoided, especially if the storage period is long, as it could result on wood deterioration and later problems with transportation, elevation and manipulation of the drums. Cable without UV protection may also deteriorate being outdoors. Frequently rolling shall be avoided and in any case, the original way of rolling of the cable in the drums must be followed in order to avoid opening of the spires and cable touching the floor. Impact damage can be prevented by the following precautions: Aligning reels flange to flange. Using guards across flanges when different reel sizes are stored together. Maintaining adequate aisles and barricades to prevent equipment from hitting the cable. Seal the ends of all cable stored outdoors, and re-seal both ends when a length is cut from the reel. That will prevent ingress of water or other substances into the cable. 2.4 Cable inspection Inspect every reel of cable for damage before accepting the shipment. Be particularly alert for cable damage if: A reel is laying flat on its flange side. Several reels are stacked on top of each other. Other freight is stacked on top of a reel. Nails have been driven into reel flanges to secure shipping blocks. A reel flange is damaged. A cable covering has been removed, or is stained or damaged. A cable end seal has been removed or is damaged. A reel has been dropped (hidden damage likely). PRE-INSTALLATION CHECKLIST Code review Review all applicable project, regional and national codes relating to cable installation. Consult project inspection authority. Cable inspection Check for shipping damage before accepting shipment. Record any damage on the way bill. Confirm that the cable specified was received. Verify that the cable end seals are intact. 74
Cable handling Remove nails and staples from reel flanges. Calculate and comply with recommended bending radius. Use swivels. Cable storage Provide firm support for reels. Protect cable from mechanical damage and from liquid spills. Check cable end seals periodically. Advise all splicers, installers and handlers of all special instructions. 3. INSTALLATION A high percentage of cable failures are due to mechanical damage, which typically occurs during transportation, handling and installation. In fact, most cables are subjected to more mechanical stress during installation than they ever experience in actual operation. Needless to say, handling and installing the cable according to the manufacturer s recommendations is extremely important. When cables are installed, the following factors must be considered: Conductor configuration. Way or cable tray fill. Physical limitations of cables. Installation equipment. Ambient temperature and conditions. Requirements for securing and supporting the cables.

3.1 Equipment The proper use of appropriate equipment is crucial to a successful cable installation. The equipment recommended for a variety of installations is listed in the following list and the appropriate equipment should be selected for particular installation requirements: Dynamometer Basket grip pullers Cable cutter Cable end seals Cable pulling lubricant Cable tray bend sheaves Cable tray rollers Capstan-type puller Diameter tape Duct cleaning mandrels Electric safety blankets and clamps Floodlights Gang rollers Gloves Tester Measuring tape Personal Protection Equipment Pulling rope Pump Reel arbour Reel brakes Reel jacks Several wire rope slings of various lengths Swivels Signals / 77
78 3.1.1 Feed-In setups
Single sheave Single sheave should only be used for guiding cables. Arrange multiple blocks to maintain bending radius whenever cable changes direction or elevation. Sheave assembly For pulling around bends, use conveyor sheave assemblies of the appropriate radius series. The pulleys must be positioned to ensure that the effective curvature is smooth and changes direction or elevation evenly at each pulley. Never allow a polygon curvature to occur as shown: 79
3.1.2 Pulling Loads Cables shall be so installed that the tensile stress applied to them either by reason of their own weight or for any other reason is minimised. The mechanical strength of conductors shall be sufficient for the installation and working conditions and the cross sectional area of the conductor shall not be less than 0.5 mm2. This is particularly important for cables of small cross-section and for cables on vertical runs, or in vertical pipes. These cables shall be suitably supported. Cables must be pulled with a system that enables the control of the pulling speed and the pulling load and if possible it shall be equipped with an automatic mechanical switch that will act in case the pulling load is over the previously established limit. The best option is to lay the cable applying the load to the cable through a sleeve connected to the cable conductor. This sleeve includes a ring to fix the steel cable from the pulling equipment. Maximum loads to avoid cable damages are defined as 5 kg/mm2 for Copper conductors and 3 kg/mm2 for Aluminium conductors. Cable pulling may use pulling sleeves made of a steel wire braid with an end ring, in such a way that after introduction of the cable in its interior, it will be radically compressed proportionally to the cable load. This method is less advisable as a certain cable length is damaged and must be removed, due to the radial pressure. In case of manual laying of cable it is important to distribute the load along the length, using a number of people in accordance with the cable length and numbers of rolls. If the cable contains a galvanized steel wire armour the load may be applied to the armour. In any case it should be as uniform as possible avoiding sudden efforts. In very special cases where a significant length of cable is suspended (i.e. vertical length) it may be required a steel rope to which the cable is tied every 1 to 2 meters. 80
3.1.3 Supporting rolls, and cable fixing It is very important to use aligning rolls to facilitate a smooth slippage of the cable and avoid its eventual contact with other elements that may damage it. The base must be sufficiently wide and safe to guarantee the stability of the drum during the unrolling of cable. The drum must be placed a minimum of 10 cm above the floor. The use of adequate rolls makes the slipping of the cable easier and reduces the pulling load. They must roll easily and include an appropriate basis to avoid its turning and a guide through which the cable passes. The distance between the rolls must be in accordance with the cable weight and flexibility characteristics, avoiding excessive distances between them, causing significant ondulations on the cable. Regarding supports and fixing, with the exception of cables for portable appliances, and those installed in pipes, conduits, trunkings or special casings, cables shall be fixed by means of clips, saddles or straps of suitable material which, if ignited, shall not contribute to any spread of flame along the cables or insulated wire. The material shall have a surface area sufficiently large and be shaped such a that the cables remain tight without their coverings being damaged. The distances between supports shall be chosen according to the type of cable and the probability of vibration. It shall not exceed 400 mm for horizontal cable run where the cables are laid on cable supports in the form of tray plates, separate support brackets or hanger ladders. The spacing between the fixing points may be up to 900 mm, provided that there are supports with maximum spacing as specified above. This exemption shall not apply to cable runs along weather decks, when the cable run is arranged so that the cables can be subjected to forces by water washing over the deck. Cables with Class 5 conductors may require additional support to prevent sagging. The supports and the corresponding accessories shall be robust and shall be of corrosion resistant material or suitably treated before erection to resist corrosion. When cables are fixed by means of non-metallic clips or straps, and are not laid on top of horizontal cable trays or cable supports, suitable metal cable clips or saddles shall be added at regular distances not greater than 1 m in order to prevent the release of cables during a fire. 81
Cable clips or straps used to support cable for use in high fire risk areas and safety escape routes shall be metallic unless for single core cables where clips shall be non-magnetic. 3.2 Installation temperature Low temperatures are cause of concern when installing cable. Cable should not be installed when temperatures are less than the cold bend temperature rating of the cable product plus 15ºC ( i.e., when installing a cable with a cold bend temperature rating of -25ºC, the minimum recommended installation temperature is -10ºC. The cold bend temperature ratings are indicated on the catalo spec. sheets and could be different depending on the different sheathing and insulating compounds. Prior to performing a low temperature installation, it s recommended to store the cable during 24h at a minimum temperature of 13ºC. The cable should be pulled more slowly and trained in place the same day it is removed from storage. Do not impact, drop, kink or bend cable sharply in low temperatures. 3.2 Bending radius The internal bending radius for the installation of cables shall be as recommended by the manufacturer to the type of cable chosen and shall not be less than the values given in the following table: Bending radii for cables rated up to 1,8/3kV Cable construction Insulation Covering Overall diameter of cable (D) Minimum internal radius of bend Unarmoured or unbraided 25 mm 25 mm 4Dª 6D Metal braid screened or armoured Any 6D Thermoplastic or thermosetting with circular copper conductors Metal wire armoured Metal tape armoured or metal-sheathed Composite polyester / metal laminate tape screened units or collective tape screening Any Any 6D 8D Thermoplastic or thermosetting with sector shaped copper conductors Any Any 8D ª 6D for defined circuit integrity 82

MV power cables, higher than 1,3/3kV 3 conductors Instrumentation cables 150/250 V Pair Triad Two pairs (collective screen) Two pair cables collectively screened are laid up with diametrically opposite cores. 1 2 2 1 3.5 Especial precautions for single core cables for a.c wiring: a.c. wiring shall be carried out, as far as possible, in twin or multicore cables. When, however, it is necessary to use single core cables for circuits rated in excess of 20 A, the following precautions shall be observed: a) The cables should either be non-armoured or they should be armoured with non-magnetic material. In order to avoid current loops, the metallic screen should be earthed at one point only. The free end of the metallic screen shall be sufficiently insulated to protect against high voltages induced by short circuit currents. b) Conductors belonging to the same circuit shall be contained within the same pipe, conduit or trunking, or the clamps, which fix them, shall included all the phases, unless they are made of non-magnetic material. c) When installing two, three or four single core cables forming respectively single phase circuits, three phase circuits or three phase and neutral circuits, the cables shall as far as possible be in contact with one another. In every case, the distance measured between the external covering of two adjacent cables shall not be greater than one cable diameter (De). 84
d) When single core cables having a current rating greater than 250 A must be installed near steel bulkhead, the clearance between the cables and the bulkhead shall be at least 50mm, unless the cables belonging to the same a.c. circuit are installed in trefoil formation. e) Magnetic material shall not be used between single core cables of a group. Where cables pass through steel plates, all the conductors of the same circuit shall pass through a plate or gland, so made that there is no magnetic material between the cables, and the clearance between the cables and the magnetic material shall be not less than 50 mm, unless the cables belonging to the same circuit are installed in trefoil formation. f) In order to try to equalise the impedance of three phase circuits ( of considering length, or consisting of single core cables of a conductor cross-section of 185mm 2 or larger), a transposition of the phases shall be effected at intervals not exceeding 15m. The above precautions are, however, not necessary when the cables are installed in trefoil formation. g) In circuits involving several single core cables in parallel, per phase, all cables shall follow the same route and have the same cross-sectional area. Further, the cables pertaining to the same phase shall be as far as practicable alterned with those of the other phase so that unequal division of the current is avoided. For instance, in case of two cables per phase, the correct dispositions are as follows: L 1 L 2 L 3 L 1 L 2 L 3 L 3 L 2 L or 1 L 3 L 2 L 1 Whereas the following dispositions are unacceptable: L 1 L 1 L 2 L 2 L 3 L 3 or L 1 L 2 L 3 L 1 L 2 L 3 85
3.6 Cable type selection 3.6.1 Power cables In the voltage designation of cables U0 / U / (Um): U 0 is the rated power voltage between conductor and earth or metallic screen for which the cable is designed. U is the rated power frequency voltage between conductors for which the cable is designed. (U m ) is the maximum value of the highest system voltage which may be sustained under normal operating conditions at anytime and at any point in the system. It excludes transient voltage conditions and rapid disconnection of loads. U m is chosen to be equal to or greater than the heights voltage of the three-phase system. Where cables are permitted for use on circuits where the nominal system voltage exceeds the rated voltage of the cables, the nominal system voltage shall not exceed the maximum system voltage (U m ) of the cable. The choice of standard cables of appropriate voltage designations for particular systems depends upon the system voltage and the system earthing arrangements. The rated voltage of any cable shall not be lower than the nominal voltage of the circuit for which it is used. To facilitate the choice of the cable, the values of U recommended for cables to be used in three phase system, are listed in the next table in which system are divided into the following three categories: Category A. This category comprises those systems in which any phase conductor that comes in contact with earth or an earth conductor is automatically disconnected from the system. Category B. This category comprises those systems that, under fault conditions are operated for a short time, not exceeding 8 hours on any single occasion, with one phase earthed. For example, for a 13,8 kv system of Category A or B, the cable should have a rated voltage not less than 8,7/15 kv. Category C. This category comprises all systems that do not fall into Categories A and B. 86
The nominal system voltages from 1,8/3 kv to 8,7/15 kv shown in table 1 are generally in accordance with Series 1 in IEC 60038. For nominal system voltages intermediate between these standard voltages and also between 0,6/1 kv and 1,8/3 kv, the cables should be selected with a rated voltage not less than the next higher standard value. For example:- A first earth fault with one phase earthed causes a 3 higher voltage between the phases and earth during the fault. If the duration of this earth fault exceeds the times given for Category B, then according to Table 1, for a 6 kv system, the cable is to have a rated voltage not less than 6/10 kv.

In some instances for conductor sizes 1,5 mm2 and larger, or when circuits are to be supplied from a low impedance source, 0,6/1kV rated cables are specified for use as control or instrumentation cables. 3.7 Cross section area of conductors and current carrying capacities 3.7.1 Cross section areas of conductors The cross section area of each conductor shall be selected to be large enough to comply with the following conditions: The highest load to be carried by the cable according the installation. The corrected current rating and the highest current to be carried by the cable. The voltage drop in the circuit according the regulatory body. 87
The cross section area shall be able to accommodate the mechanical and thermal effects of a short circuit current. Class 5 conductors has, in most of cases, a lower conductivity than the equivalent class 2 conductor of the same nominal cross section area. The cross section area for the earth continuity conductors shall comply the following table: Arrangement of earth conductor Cross section Q of associated current carrying conductor (one phase or pole) mm 2 Minimum cross-section of earth conductor 1 i) Insulated earth conductor in cable for fixed installation. Q 16 Q ii) Copper braid of cable for fixed installation. iii) Separate, insulated earth conductor for fixed installation in pipes in dry accommodation spaces, when carried in the same pipe as the supply cable.

Q 16 Q > 16 Same as current-carrying conductor. 50 % of the current-carrying conductor, but minimum 16mm 2. ª The term protective conductor is accepted as an alternative term for earth continuity conductor. 88
3.7.2 Current carrying capacities The procedure for cable selection employs rating factors to adjust the current carrying capacities for different ambient temperatures, for the mutual heating effects of grouping with other cables, methods of installation and short circuit time duty. Guidance on the use of these methods are given in IEC 60092-352. Current carrying capacities in continuous service at maximum rated temperature of 90ºC in accordance with IEC 60092-352 at ambient temperature 45ºC are as defined in the following table: Conductor temperature 90ºC Nominal crosssectional area (mm2) Single core (A) 2 cores (A) 3 or 4 cores 1,5 23 20 16 2,5 30 26 21 4 40 34 28 6 52 44 36 10 72 61 50 16 96 82 67 25 127 108 89 35 157 133 110 50 196 167 137 70 242 206 169 95 293 249 205 120 339 288 237 150 389 331 272 185 444 377 311 240 522 444 365 300 601 511 421 d.c. a.c. d.c. a.c. d.c. a.c. 400 690 670 587 570 483 469 500 780 720 663 612 546 504 600 890 780 757 663 623 546 89
These carrying current capacities in continuous service must be adjusted for ambient temperature other than 45ºC according the following table: Max conductor temperature (ºC) Ambient air temperature 35º 40º 45º 50º 55º 60º 65º 70º 75º 80º 90 1,10 1,05 1,00 0,94 0,88 0,82 0,74 0,67 0,58 0,47 3.8 Other considerations on the cable selection 3.8.1 Mechanical protection In situations where there is a risk of mechanical abuse, cables shall be enclosed in suitable conduits or casings, unless the cable covering ( armour or sheath ) provides adequate protection. Metallic braiding and/or armouring can be used as mechanical protection for the cable in accordance with IEC 60092-350 The coverage density of the braid shall be such that the weight of the braid is at least 90% of the weight of a tube of the same metal, having an internal diameter equal to the calculated internal diameter under the braid and a thickness equal to the nominal diameter of wires forming the braid. In situations where there is an exceptional risk of mechanical damage ( holds, storage, cargo specs ) cables shall be protected by steel casing, turnking or conduits. For single pole cable constructions, armouring and braiding must be non magnetic material. Bare Copper performs better than galvanised steel and is therefore used throughout full range of cables. Installation in Metallic Pipes or Conduits or Trunking When cables are installed in metal tubes, conduits or trunking, the following precautions shall be observed. The pipes, conduits or trunking shall be suitably smooth on the interior and protected against corrosion. The pipes or conduits or trunking shall have their ends shaped or bushed in such a way so as not to damage the cable covering. 90
The pipes or conduits or trunking shall have such internal dimensions and radius of bend that will permit the easy drawing in and out of the cables which they are to contain: the internal radius bend shall be not less than those permitted for cables and, for pipes exceeding 63 mm external diameter, not less than twice the external diameter of the pipe. Pipes, conduits and trunking shall be so arranged that water cannot accumulate inside them (account being taken of possible condensation). The space factor (ratio of the sum of the cross-sectional areas corresponding to the external diameters of the cables to the internal cross-sectional area of the pipe or conduit or trunking) shall not be greater than 0.4. If necessary, ventilating openings shall be provided, preferably at the highest and lowest points, so as to permit air circulation and to obviate the possibility of water accumulating at any part of the pipe, conduit or trunking run. These ventilation openings should not be made if their inclusion will increase the fire risk. If there is reason to fear that a tube may break because of its length, appropriate expansion joints shall be provided. This might be the case when cable pipes are fitted along weather decks. Where cables are to be drawn into pipes or conduits or trunking, draw boxes shall be installed where necessary in order to ensure that the cables are not damaged during installation. Installation in Non-Metallic Pipes, Conduits, Trunking, Ducts or Capping and Casing. Cables may be installed in non-metallic pipes, conduits, trunking, ducts or casings either on surface or concealed behind ceilings or panelling, provided the following precautions are observed. If the fixing of capping is by means of screws, they shall be of non-rusting material arranged so as not to damage the cables. The capping shall be readily accessible. Non-metallic pipes, conduits, trunkings, ducts or cappings and casings shall, if ignited, limited the spread of flame in accordance with IEC publications. The spread of flame along the cables shall not be significantly impaired by the use of such pipes, conduits, trunkings, ducts or capping and casings, paints or other coatings. 3.8.2 Cable runs Cable runs shall be selected so as to keep the number of bends to a minimum. In the selection of cable runs, account shall be taken of the need for protection against destructive pests or rodents. 91
Cables having insulating materials with different maximum permissible conductor temperatures shall not be bunched in a common clip, cable transit, conduit, trunking or duct. Where this is impracticable, the cables shall be rated so that no cable reaches a temperature higher than the lowest rated cable temperature within the bunch. Cables having a protective covering which may damage the covering of more vulnerable cables shall not be bunched with the latter in a common clip, gland, conduit, trunking or duct. Cables having a bare metallic sheath or braid or armour shall be installed in such a way that corrosion e.g. galvanic or electrolytic by contact with other metals, is prevented. Cable runs shall be selected so as to avoid action from condensed moisture or drip. Cables shall, as far as possible, be remote from sources of heat such as boilers, hot pipes, resistors, etc., and protected from avoidable risks of mechanical damage. Where installation of cables near sources of heat cannot be avoided, and where there is consequently a risk of damage to the cables by heat, suitable shields shall be installed, or other precautions to avoid over heating shall be taken, for example, use of special ventilation, installation of heat insulation materials, or use of special heat resisting cables. Cables shall not be installed across expansion joints. If however, it is unavoidable, a loop of cable having a length proportional to the expansion of the joint shall be provided. The minimum internal radius of the loop during operation shall never be less than twelve times the external diameter of the cable. The flame spread performance of cables installed in bunches can be affected by a number of factors including the method of installation. (See IEC 60332) In the case of essential electrical equipment for which it is mandatory to have at least two supplies, for example, steering gear installations, the supply and any associated control cables shall follow different routes, which, as far as practicable, shall be separated both vertically and horizontally. In the case of duplicated essential electrical equipment, the supply and any associated control cables shall follow different routes, which shall be separated both vertically and horizontally as far as practicable. Where it is required to divide an offshore unit into fire zones (such as is generally the case of passenger areas), cable runs shall be so arranged that a fire in any main vertical fire zone will not affect operation of essential services in any other such zone. This requirement will be met if main and emergency cables passing through any zone are separated both vertically and horizontally as widely as is practicable and not passing through the same horizontal zone. 92
Cables and wiring serving essential or emergency power, lighting, internal communications or signals shall so far as practicable be routed clear of galleys, laundries, machinery spaces and their casings and other high fire risk areas, except for supplying equipment in those spaces. They shall be run in such a manner as to preclude their being rendered unserviceable by heating of the bulkheads that may be caused by a fire in an adjacent space. When it is essential that a cable shall function for some time during a fire and it is unavoidable that the cable for such a circuit is routed through a high risk area it shall be as follows: With limited circuit integrity properties in case of fire, fulfilling the requirements of the test method according to IEC 60331 or alternatively, adequate protection shall be provided against direct exposure to the fire and against mechanical damage which may occur on the site of the installation. The outer sheath of the cable shall be coloured blue for cables with limited circuit integrity in case of fire. In respect of the prevention of fire damage to cables, special attention shall be given to the protection of main cable routes for essential circuits as, for example, between machinery spaces and the navigation bridge area, taking into account the fire risk existing in accommodation spaces. 3.8.3 Fire performance All cables or insulated wiring shall meet the requirements for flame spread as given in: IEC 60332-1 and IEC 60332-3-22. NOTE - 1: It cannot be assumed that, because a cable or an insulated wire meets the requirements of IEC 60332-1, a bunch of similar cables or insulated wires will behave in a similar manner. The flame spread performance of bunched cables is assessed by the requirements of IEC 60332-3-22. This performance requirement (i.e. for cables mounted vertically in a touching formation) has been chosen to best reflect the installation conditions generally observed on board ships. Experience has shown that the test for the flame spread of cables installed vertically is adequate for horizontal installations, all other parameters being generally the same. For systems required to maintain electrical circuit integrity under fire conditions, e.g. for fire alarm, fire detection, fire extinguishing services, remote stopping and similar control circuits, the cables shall meet the requirements of IEC 60331-21. Requirements for smoke emission and acid gas evolution shall be considered, and where applicable the cables evaluated in accordance with the following test methods, cables shall meet the requirements specified in the individual product standard: IEC 61034-2Part 2; IEC 60754-1Part 1 and IEC 60754-2 Part 2. 93
3.8.4 Flexibility for an easy installation When rules and regulations of local, regional, project or certification body permits the use of class 5 multistrand flexible Cu conductors according IEC 60092-350, cables with cross section area higher than 50 mm 2 can be made with Sectorflex technology. This technology provides the cable with more handeable properties: More flexibility. More compact, smaller diameter, lighter weight. More cable per drum / coil. Same section and transport capacity as circular section. Use of conventional terminations and accessories. Sectorflex More compact, smaller diameter, lighter weight. Use of conventional terminations and accessories. 3.8.5 Hydrocarbon, Oil and MUD resistance properties. For specific oil production facilities, and according to the classification and certification bodies for each project, Oil and MUD resistant cables could be required. These cables provides the electric installation (cable) with enhanced behaviour in specific locations where oil and MUD s are present. 94
