Mining Cable
Type SHD-PCG Three-Conductor Portable Power Cable 2kV
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:EPR.
- Insulation Shield:Non-conducting Tape + Tinned copper/textile braid.
- Control Group (3 Conductor):Tinned copper conductor, EPR insulation and thermosetting sheath. Colour of insulation: Black, white and red.
- Grounding Conductor:Tinned copper conductor, located in the center of the cable.
- Sheath: Reinforced extra-heavy-duty Chlorinated Polyethylene(CPE), black. Other sheath materials can be offered upon request.
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.
