11 KEI WIRES & CABLES HT Cables KEI manufactures HT XLPE cables up to 132KV conforming to National and International Standards at Bhiwadi plant. KEI has State of Art HT cable plant with German technology. The manufacturing capability is upto 132KV, however at present we offer cable range upto 66KV. We have Two CCV line with a Single point triple extrusion and computerized sophisticated control and monitoring systems. The CCV line at Bhiwadi was imported from Machinenbau Scholz GMBH & Co KG, and CCV line at Chopanki supplied paul Troester Germany. Both manufacturers renowned in CCV line technology and have supplied more than 250 lines world over. HT plant is complete with heavy duty machines for wire drawing and conductor making, laying up, armouring, sheathing and packing. The process commences with a compacted circular conductor being fed from the pay off stands into the extruder on elevated platform. The conductor passes through extruder s crosshead, it is covered first with semiconducting screen layer then the XLPE insulation, followed by the outer semiconducting core screen. This crosshead is specially designed to feed three compounds from three extruders at one point described as Singe point Triple extrusion. Thereafter, the extruded core enters and passes through vulcanizing line known as CCV line (Continuous Catenary Vulcanising) and the XLPE insulated core is cured in the process. In CV line inert atmosphere is maintained by the Nitrogen gas which is at high pressure and high temperature. This process is popularly known as Single point Triple extrusion CDCC(Completely Dry Cured and Cooled Curing) Process. Over the cured core a copper screening is provided by lapping of copper tape or for special requirements a layer of copper wires is provided. Core is tested for Partial Discharge and then as per requirement; the cores are laid up with fillers, provided with inner sheath, armoured and sheathed. Sheath can be of PVC, HDPE, FRLS, ZHFR, PCP or CSP compound. Seamless Lead Alloy E Sheath is extruded for moisture barrier, necessary for EHV Cables and Submarine Cables before Inner Sheath. KEI manufacturing plant and process ensures great XLPE cables for the new age Power sector and industry. Our modern plant takes full advantage of the new generation XLPE compounds which offer fast curing and superior electrical parameters, dimensional control and higher productivity. Triple Extrusion and CDCC process ensure contamination free cores. All three layers are bonded and core has least eccentricity and ovality. Insulation itself is free of micro voids and with negligible moisture content. To control the manufacturing process the line has been provided with many sophisticated instruments and servo controls all monitored by the computer. Important systems are: X Ray Non touch sensors of SIKORA make for thickness and dimensional control. This system continuously measures the dimensions of insulated cores. Unit has capability to measure multilayer dimensions in all directions and record and analyse the data on line. CCV tube has a Touch Less Sag control system. This ensures no marks/lines on core unlike older lines. For EHV Cables conductor pre-heater, core rotation and De-gasification facilities have been provided. Computerised control system ensures optimum efficiency, fast start up, synchronized operations of compound feeds, three extruders, CCV line gas temperature zones, pay off and takeup. Nevertheless KEI XLPE cables compare better than those produced with older plants when checked for Microvoids, Moisture content, PD levels, dielectric strength. We have strict Quality plan and fully equipped Testing laboratory to ensure cables of best quality are produced as per the design and specifications prescribed. Cables have been type tested as per International Standards. Inventory and production plans are controlled by BANN ERP system. This ensures reliable and prompt delivery and operational efficiency. KEI offers variety of designs to suit different installations viz. Aerial Bunched cables, Water tight construction, Stainless steel armouring, for Offshore and Ship installations etc. We have many satisfied customers from many countries and diverse industry.

15 KEI WIRES & CABLES CURRENT RATINGS KEI Recommendations for Current Ratings: The Current rating of power cable is defined by the maximum intensity of current (amperes) which can flow continuously through the cable, under permanent loading conditions, without any risk of damaging the cable or deterioration of its electrical properties. The value given in the tables are valid for one circuit in a three phase system under conditions specified. For grouping cables rating factors must be used. The current carrying capacities mentioned in KEI technical data are intended as a guide, to assist operating engineers in selecting cables for safety and reliability. Basic assumptions and conditions of installation :- Max. conductor Temperature : 90 C. Ambient Ground Temperature : 30 C. Ambient Air Temperature : 40 C. Thermal resistivity of soil : 150 C.Cm/W Depth of laying (to the highest point of the cables laid direct in the ground ) 3.3,6.6 & 1 IkV Cables : 90 cm 22 and 33kV Cables : 105cm Max. Conductor Temperature for Short Circuit : 250 C. To obtain the maximum current carrying capacity of a cable operating at different conditions from the standard, various rating factors are to be multiplied, as follows :- I a = K x I s in amperes Where ; I a : Current rating at actual operating conditions (amperes) I s : Current rating at standard operating conditions (amperes) K : Rating factor as, applicable. 106

32 KEI PVC AND XLPE LT POWER CABLES COMPANY PROFILE KEI INDUSTRIES LIMITED is manufacturing LT Power Cables with PVC or XLPE insulation of voltage grade upto 3.3 KV conforming to various Indian and International Standard Specifications. KEI also manufactures other types of cables as listed at the end of this catalogue. CROSS LINKED POLYETHYLENE (XLPE) XLPE means cross-linked polyethylene or vulcanized polyethylene. The basic material is low density polyethylene. Polyethylene is a thermoplastic material consisting of long chain of hydrocarbon molecules. At elevated temperatures these molecules tend to move relative to one another so that the material becomes increasingly deformable and will eventually melt at the temperature around 110 O C. By means of process similar to the vulcanization of rubber the polyethylene molecules can be cross-linked. The process of cross-linking or vulcanization consists of producing chemical bonds at interval between the long molecular chain to give a ladder effect which prevents slippage between molecules. As a result of cross-linking the material becomes heat resistant and does not soften at higher temperatures. Further it has better resistance to stress cracking and good resistance to ageing in hot air. With the change of structure there is no adverse effect on electrical properties. Advantages of KEI XLPE CABLES 3 Dielectric losses are very small. 3 Higher current carrying capacity. 3 Higher short circuit rating 250 O C. as against 160 O C for PVC. 3 KEI XLPE can retain flexibility down upto - 40 O C. 3 Jointing and Termination is easy. 3 Light in weight. 3 They are not prone to fatigue damages due to vibrations or loading cycles. 3 Has better resistance to most chemicals, oils, acids, etc. 3 Can be installed along cable routes without elevation limitations.

67 KEI WIRES & CABLES Instrumentation Cables KEI Industries Limited manufactures a wide variety of cables suitable for process instrumentation. In the projects related to power generation & distribution, chemical & fertilizer industries and various other types of engineering industries, the process instrumentation plays a vita role in measurement, supervision and control of the process. Introduction of microprocessor based/ computerised instrumentation has demanded stringent quality requirements alongwith special electrical parameters for instrumentation cables. Very low level electrical signals pass between measuring end and display units/controllers which are situated far off. These low level signals are prone to external noise pickups and heavy silenuation during transmission. All this means that the cables to be used for instrumentation should be designed and manufactured very carefully, KEI with its meticulous efforts in maintaining quality, stringent in process control during manufacture and hte knowledge of cable designing, is proud to say that it is capable of supplying instrumentation cables meeting any Indian/ International standard or a specific requirement desired by project authority. The efforts done by KEI are reqarded by acceptance of our quality by the country s prime organisations such as NTPC, PDIL, EIL, BHEL, TATA s, IOCL, L&T, ABB, KRUPP Ind, BPCL., HPCL, ESSAR, SIEMENS, Electricity Boards, Reliance, IOTL, Mukand, Honeywell, etc. Range of Instrumentation Cables :- Conductor : 0.4 mm dia (0.126 Sq.mm) to 2.5 sq.mm. or higher sizes of electrolytic copper wire, Tinned/untinned, solid/stranded copper conductors.

75 CABLE SELECTION GUIDE MATERIALS COMPARISON CHART KEI offer a wide range of Materials for the purpose of insulation and sheathing. KEI is putting their effort to design the cables by careful balancing the properties of selected materials in combination with a view to meet the specific environmental and installation conditions. Any material does not possess universal properties which is suitable for all conditions. This will be evident from the comparison chart. Although this chart does not provide the detailed informations of all the materials and combinations of them with every pertinent characteristics, it is a guideline of informations which a cable specialist requires from user to ensure most appropriate design to meet specific needs.

76 Handling & Storage Handling & Storage Handling (Unloading at Site) On receipt of the cable drums visual inspection of drums should be made. While unloading the drums from the lorry/trailer, a crane or suitable derrick system with chain pulley arrangement should be used and the drums carefully lifted and deposited on the ground. When lifting the drums with the crane, it is recommended that the lagging should be kept in place to prevent the flanges from crushing on to the cable. If the crane is not available, a ramp should be prepared with approximate inclination of 1:3 or 1:4. The cable drum should be rolled over the ramp by means of ropes and winches. Under no circumstances should the drums be dropped to the ground as the shock may cause serious damage to the inner layer of the cables. Cable should not be dragged along the earth surface Cable ends should always be sealed by means of suitable end sealing materials to prevent miniaturization of cores and armour Drums should be rolled in direction of arrow marked on the drums Storage The site chosen for the storage of cable drums should be dry and covered place to prevent exposure to climatic conditions and wear and tear of wooden drums and it should be preferably on a concrete / consolidated surface which will not cause the drums to sink and thus lead to flange rot and extremely difficult in moving the drums. The drums should be stored in such a manner as to leave sufficient space between them for air circulation. It is desirable for the drums to stand on battens placed directly under the flanges. In no case shall the drums be stored flat i.e. with flanges horizontal Minimum permissible bending radius While installing the cables, the following minimum bending radius should be observed in order so that the cable, especially insulation, may not undergo damage,. Wherever possible larger bending radius should be used VOLTAGE RATING PVC & XLPE Cables KV Single core Multicore Upto D 12 D Above 1.1 to D 15 D Where D is outer diameter of cable
