| Applications | These heavy duty cables are designed for use on longwall shearers, where three shielded power conductors, three unshielded control conductors, and a grounding conductor are required. |
| Standards | ICEA S-75-381/NEMA WC 58 ASTM B 172 ASTM B 33 CAN/CSA C22.2 No. 96 |
| Construction | |
| Conductors | Stranded annealed tinned copper conductor. |
| Insulation | Ethylene Propylene Rubber (EPR). |
| Insulation Shield | Tinned copper/textile braid. |
| Control Group (3 Conductor) | Tinned copper conductor, EPR insulation and thermosetting jacket. Colour of insulation: Black, white and red. |
| Grounding Conductor | Tinned copper conductor, located in the center of the cable. |
| Jacket | Reinforced extra-heavy-duty Chlorinated Polyethylene(CPE), black. |
| Options | Other jacket materials such as CSP/PCP/NBR/PVC are available upon request. Two-layer jacket with reinforcing fibre between the two layers can be offered as an option. |
