3 cable solutions and services cable solutions and services Mining companies are focusing on long-term growth, as well as short-term gains. They would like to enhance their operational viability and social legitimacy, and this can only be done through modernization, industrialization and automatisation of their infrastructure, always with worker and environmental safety in mind. Since cables are the only means of getting power to the electrical mobile machines, they play an important part in the strategic planning of all mining operators. Sustainability is a concern, not only in terms of protecting present and future geological assets, but also in obtaining public support in a sector which raises questions about biodiversity, water-usage, climate change, energysharing, international cooperation, and the development of public transport and communications networks. What mining companies and specialised mining and tunneling EPCs expect: Wide range of cables for all mining applications (power, control and data). Turnkey solutions to allow the complete outfitting of a mine. Ruggedness, flexibility and longevity in very harsh environments. Pre-terminated cable assemblies for fast installation. Full compliance with world standards, including ICEA, NEMA, MSHA, CSA, SABS, AS/NZS, DIN/VDE, GOST, AENOR, AFNOR, etc Lab test services and on-site inspection. Cable repair workshop and facilities (4/7 hotline) and corresponding training. To meet the extraction, loading and transport challenges of today s mining companies, Nexans has developed and TIGER cables and cable solutions for both underground and surface sites. Since high performance and reliable support are essential to economic efficiency, Nexans also provides numerous services based on our proven experience in the mining market. Underground coal cutter cables offer durability and tensile strength, while loader/scooper cables allow electric trucks to travel long distances in galleries when conveyors are unavailable. Shaft and gallery cables can be designed for easy installation and superior fire-performance to protect personnel and equipment. Drilling and tunneling cables give boring machines greater autonomy. Surface mining cables are designed to withstand mechanical forces and to provide nonstop power supply and reliable control for conveyors, excavators, pontoonmounted dredgers, electric shovels and draglines. For both types of mining, composite cables comprising optical fibres and copper conductors can be integrated for remote control, surveillance and monitoring, often using an active switch system to provide Power over Ethernet (PoE) to vital equipment. Nexans has also developed submersible cables to handle groundwater drainage, and fluorescent/ reflective cables to give the night-time visibility of exposed cable. Mining-related services include testing, onsite repair, training for personnel, and programs to support environmental and social values. Since easy-to-reach deposits are being depleted worldwide, exploration has moved farther afield to remote locations, often with desert or freezing conditions. Nexans high performance cables are designed for challenging environments, and we can also advise about infrastructures beyond pure mining applications which are increasingly the responsibility of mining companies: like private communications and data networks, self-contained electrical power distribution, short-link rail infrastructure and material handling facilities for loading centers and ports. Tunneling Due to their technological similarities, all dynamic and static tunneling cables tend to be considered worldwide as mining cables. But in fact tunneling activities are generally rather linked with transportation infrastructure, like highways', railways' or subways' tunnels civil works part. Surface mining and TIGER operational excellence and safety Reliable, customized cable solutions to increase economic efficiency. Built-in safety to handle short-circuits, fire, abrasion, impact, crush/breakage. Designs for long freehanging installations, extended links, and tough conditions. High flexibility for the very mobile mining environment, underground and surface. Technical support for system engineering, fast-delivery, installation and problem solving. Underground mining Pre-terminated sets, harnessing, splicing, onsite repairs and maintenance. Advanced testing facilities to ensure durability and worldwide certification.

4 Mining cable types Mining cables can be divided into main categories: Infrastructure Dynamic excavation mining & tunneling cables these mobile cables (reeling and trailing cables) present higher requirements in terms of mechanical resistance and flexibility than the usual fixed installation cables. For this reason they are designed and tested according to very stringent national or international standards. Static or semi-static excavation mining & tunneling cables being mechanically less challenged than the dynamic cables, these typically include shaft or gallery cables for underground mines, or conveyor belt cables, present simpler design and construction. cables for downstream processing plants these cabling solutions are equipped for crushing, washing or mineral processing plants and the electrical and mechanical requirements are usually simpler and correspond to general industrial standards. Remark: tunneling cables are often very similar, and can physically correspond to either of the above mentioned categories. 6 7

8 Surface mining Surface mining In surface mining you find an array of different cable needs for both fixed and mobile installations in mines where electrification is the main source of power. The main cable requirement is found in reeling and trailing applications. These types of cables are used to feed power to mobile equipment such as excavators, shovels, draglines and drills and are subjected to rigorous operational and environmental conditions such as lateral movement across harsh terrain, twisting, and bending. Nexans and TIGER range of dynamic cables offer both the flexibility and durability to counter such conditions and innovative designs help to provide greater levels of safety and productivity. In addition to reeling & trailing cables you will find a requirement for other types of cables that are essential in the day to day operational function of the mine, such as feeding 5 power to conveyors and transformers. For this Nexans and TIGER range of semi-static and static cables are offered and where necessary integrate both fibre optic and/or control cables to maximise efficiency and cost. 5 MV trailing cable with rubber sheath and pilot wires, acc. to US standards (ICEA / NEMA).

9 Surface mining Insulation Screens Sheath Reeling and trailing mobile mining cables: key features & constructions Rubber or polyurethane sheathed cables are the natural choice for applications where durability, flexibility, and safe operation under extreme environmental conditions are important. Nexans and range of cables have demonstrated their robustness in thousands of operations, and present the best features and the broadest range of mining cables offered around the world. In all countries where the mining industry has experienced a very long historical development, many well defined standards or guidelines govern the manufacture and the application of dynamic, semi-static and static mining cables. Innovation in work practices, with increasing number of excavation equipment operating at always higher voltages, has required the continued development of new rubber or polyurethane sheathed cable designs. The key objective of all development programs for several decades was always the continuous improvement of the reliability and safety of all cables designs. The major design responsibility for and range aims at ensuring that all cables supplied will operate reliably and safely under all kinds of difficult conditions. Personnel often work close to energised cables, especially in underground mines. The cable construction and materials must be selected to provide maximum safety during both normal operation and in the case of cable failure. Example of reeling or trailing dynamic (mobile) cable, used as well in surface mining as in underground mining (Type according to ICEA / NEMA / MSHA).

11 Underground mining Underground mining In underground mining you find an array of different cable needs for both fixed and mobile installations in mines where electrification is the main source of power. Here the requirement covers both fixed and mobile installations. For mobile equipment such as longwall shearers, continuous miners, and loaders, Nexans and TIGER range of dynamic cables offers the necessary flexibility and durability to meet operational conditions. Another key area for underground mining where cables are an integral requirement, are fixed installations such as shaft and gallery. Mechanical properties here are essential in ensuring the safety of the workforce. Nexans and TIGER range of static and semi static cables offer security in construction and innovative designs.. Thermoplastic insulation. Thermoplastic sheath. Free hanging shaft technology 4. Armouring with various designs: a) steel wires or steel tapes for horizontal gallery cables. b) round or flat steel wires for vertical shafts, up to 500 m depth.

Rock quality, concrete covered wall & ceiling conditions can often influence the cable design to ensure the safe installation of the cables using either single point suspension, clamping points and other installation methods. In addition to its dynamic, static and semi-static range of cables, Nexans offers its innovative free hanging technology for vertical shafts and expertise in braking drums, pulleys and other installation tools MV shaft cable with PVC sheath (N)GSEYRRGY, in line with German standards (VDE).

12 Underground mining Insulation Fillers Sheath Static cable : key features & constructions For typical static applications, cross-linked insulations and thermoplastic sheaths are generally specified, as well as semirigid conductors (Class ). Depending upon the installation method and position of the cable (vertical or horizontal), it will have to be more or less strongly reinforced to withstand the rough environment or the challenging installation technique. For this, different types of constructions are used, mainly differing by the type, size and resistance of the armour. The historical evolution of underground mining has led to a strong increase of the vertical shafts depth, combined with high requirements in terms of safety factors. For example it is often required that the steel armour tensile strength must be 5 times higher than the cable weight calculated for the free hanging portion. These factors can lead to very high tensile strengths, up to more than 70 metric tons (8 short tons). For several decades, the key objective of all development programs has been the continuous improvement of the reliability and safety of all cable designs, both from electrical requirements perspective, as from mechanical and environmental requirements perspective. Cable design has evolved with the development of better insulation compounds, sometimes allowing wall thickness reductions to reduce the cable weight, and also with the introduction of continuously reinforced steel qualities, in order to enhance the safety factor for the tensile strength of the cables. Example of static cable, used in underground vertical shafts either with regular clamping or with single-point-of-suspension techniques (Type (N)GSEYRRGY, in line with VDE German standards) Long lasting insulation properties => very low partial discharges and good mechanical properties. Construction: polyethylene (XLPE) or Ethylene-Propylene Rubber (EPR) with inner and outer semiconductor layers. Fillers (in the picture), but can also be replaced by Ground wires Long lasting mechanical stability for the insulations. Construction: Generally class 5 tinned copper conductors without insulation.. Protect the underlying core assembly from mechanical, chemical, or other environmental damage.. Long lasting mechanical strength despite rough environmental conditions (heat, humidity, ). Construction: PVC or PE sheath, sometimes halogen free flame retardant compound required. Conductors Screens Bedding Armour Very good electrical and mechanical properties. Construction: Annealed stranded semi-rigid copper conductors (Class ).. Flexibility and good contact with the ground wire. Long lasting mechanical strength. Construction: helically applied layer of wires, or copper tape, sometimes completed by semiconductive tapes underneath. Long lasting mechanical strength. Construction: PVC or PE sheath, sometimes halogen free flame retardant compound required. High tensile strength, and / or very high crush resistance, allowing to withstand the important radial compression linked either with the laying technique or with the clamping method in case of vertical position. Construction: helically applied double layer of round or flat steel wires for vertical cables, simple or double layer of steel tapes for horizontally laid cables or for reduced shaft depths.

14 Tunneling Tunneling In the past decades numerous very long tunnel projects have been developed in a lot of countries, mainly for road or rail traffic and these long tunnels are often bored with tunneling machines whose electrical powering is ensured by heavy-duty flexible or semiflex cables very similar to the dynamic mining cables. For this reason they are considered as being part of the same product range. However their application can vary from one tunnel project to another, and both main categories of cables as mentioned in the precedent chapters are commonly used: A. Static cables can be installed in a fixed manner from the feeding end of the tunnel to the interconnection point with the heavy duty trailing or reeling dynamic cable. B. Dynamic cables are systematically connected to the tunneling machine. VERTICAL SHAFT CABLE CLAMPING MV trailing cable with rubber sheath and pilot wires, acc. to US standards (ICEA / NEMA).

15 Mining infrastructure Mining infrastructure and downstream processing plants All downstream processes of the commodities extracted by the mining industry require growing capacities of grinding, crushing, washing, concentrating, refining plants, whose reliability and productivity is directly linked with their power and control networks. For all power, control, instrumentation, compensation, earthing, communication, supervision and measurement applications, Nexans can provide a full range of cables covering all common electrical, mechanical and environmental standards. Mining infrastructure cables Construction standards: There are many cable design standards in the industrial sectors, among these, IEC 6050-, IEC 6050-, BS 508-, BS 508-, BS 5467, BS 674, BS 6446, EEMUA. IEC and IEC Power cables with extruded insulation and their accessories for rated voltages from kv (Um=. kv) up to 0 kv (Um=6 kv). These international standards are divided in two different parts, defining construction, dimensions and test requirements of power cables having extruded solid insulation. IEC is applicable for cables having voltage ratings from kv (Um=. kv) up to kv (Um=.6 kv), while IEC defines construction rules for cables having voltage ratings from 6 kv (Um=7. kv) up to 0 kv (Um=6 kv). These standards include cables which exhibit properties of reduced flame spread, low levels of smoke emission and halogen free gas emission when exposed to fire. On fire behaviour, flame spread tests have to be performed on ST, ST or SE over sheathed cables only when specially required. BS Electric cables Thermosetting insulated, armoured cables for voltages of 600/000 V and 900/00 V. This standard reference defines construction requirements and gives test methods for an armoured cable having thermosetting insulation. Cables specified in this standard are intended for use in fixed installations in industrial areas, buildings and similar applications. The insulation and other components are suitable to permit operation of the cables at a maximum sustained conductor temperature of 90 C and for a maximum short circuit conductor temperature of 50 C. Standard BS 674 defines requirements for construction and establishes test methods for armoured cables having thermosetting insulation of rated voltages 600/000 V and 900/00 V for production of lower levels of smoke and corrosive products when exposed to fire comparable with cables complying with BS Standard BS 646 specifies requirements for construction and describes methods of test for armoured cable with PVC insulation of rated voltages 600/000 V and 900/00 V. Cables specified in this standard are intended for use in fixed installations in industrial areas, buildings and similar applications. BS508- and BS Instrumentation cables. BS 508- standard describes requirements for and dimensions of polyethylene insulated cables in pairs with or without screens and optionally incorporating single wire armour or lead sheath with single wire armour. BS 508- standard describes requirements and dimensions of PVC insulated cables, in multicore and multipair construction, with or without screens and optionally incorporating single wire armour. MV CABLES LV CABLES OPTICAL FIBER CABLES CONTROL CABLES INSTRUMENTATION CABLES The insulation of instrumentation cables is suitable for operation at voltages up to 00 V r.m.s. core to earth and 500 V r.m.s. core to core. ALLIPHATIC AND AROMATIC HYDROCARBON RESISTANT CABLES Instrumentation cables are not for direct connection to low impedance sources, e.g. public mains electricity supply. DATA CABLE 8 9

17 Innovations In the past decade numerous innovations were aimed at strongly improving the visibility and the identification of the mining cables, and for this several important developments were introduced: Coloured sheaths Nexans Chlorinated Polyethylene (CPE) sheath provides the physical performance and strength needed to resist wear, tear, abrasion and compression cuts caused by everyday mining use. This tough, durable sheath is a proven performer in mines throughout the world. Nexans engineered cable construction includes a taped core with fillers or integral filled and tandem extrusion of the sheath layers. Two-pass sheaths, extruded in tandem, yield an inseparable bond between the layers. Integral filling of the cable core reduces torsioninduced damage. Nexans CPE colored sheaths have the identical physical properties of our standard black sheath. These high visibility cables can improve mine safety by providing easy circuit identification. TPU Jackets Colour stripes Nexans provides additional colour combinations by vulcanising a contrasting coloured stripe into the sheath of our round CPE cables. Shown below are a few examples of the many possible sheath / stripe combinations. Consult with your Nexans specialists for a complete list of available stripe options. Stripe options Reflective stripes Nexans reflective Stripes can extend cable life by reducing run-overs in low visibility situations and improve mine safety by providing easier visual circuit identification. For this options exist in Nexans product range: A/ Reflective stripes directly incorporated at the surface of CPE sheaths ( types with high class mold curing system). B/ Reflective tapes applied underneath the outer sheath thanks to a patented transparent polyurethane (TPU) outer layer. A B Shaft cables More and more underground mines reach depths greater than km, and the design, laying techniques and clamping solutions for vertical shaft cables have strongly evolved in the past decades.. Nowadays, almost every new high depth shaft needs a customised solution to cope with the transported power, and its corresponding voltage level and cable cross-section, with the shaft dimension and design (concrete-lined shafts or not) and with the fixture system required. Fundamentally we distinguish between: Clamped cables with regular clamping intervals (typically 5 to 0 meters), where the highest tensile load applied to the cable is only effective during the laying operation. Single-Point-of-Suspension cables (SPS) implies a single attachment point at the top of the shaft. Here the tensile load of the cable is applied during the whole life time of the cable installation. In most standardization systems the safety factor between the guaranteed tensile strength of the cable and the free hanging length is 5. For this reason, detailed engineering studies are necessary to determine the right design and construction of the cable armour, in order to: Guarantee the necessary safety factor. Example: Shaft cable with double round steel wire armour for typical shaft depths up to 800 meters and with double flat steel wire armour for high depth shafts (up to 500m). Enable a safe construction of the anchoring device at the top of the shaft, device which is fixed on the cable at the end of the production in the cable plant. Install the cable with its anchoring device either with a bottom-up pulling, top-down lowering or making attachments to the shaft wall as the reel is being lowered. Nexans can supply these engineering studies as well as the customized cable design for every: Shaft depth between 0 and 500 meters. Voltage level between 6 and 5 kv. Cross-section between 0 and 500 mm. Laying method. Clamping or SPS-anchoring methods. CPE Colours
