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.
