Trailing & towing
Primary trailing cable for electric rope shovels, walking draglines, blasthole drills, longwall shearers and mobile substations.
Product
Extra-heavy-duty shielded portable power cable to ICEA S-75-381 / NEMA WC 58 with tinned copper composite phase shields, two interstitial grounds and one ground-check pilot for electric mining shovels, draglines, drills and continuous miners.
Typical values for this cable type, based on ICEA S-75-381 / NEMA WC 58 — confirmed in the datasheet and quotation for your order.
Application fit
Type SHD-GC is the flagship North American shielded trailing and reeling cable for high-capacity surface and underground mining machinery from 2 kV through 25 kV.
Primary trailing cable for electric rope shovels, walking draglines, blasthole drills, longwall shearers and mobile substations.
Suitable for mobile cable reels on shovels, drills and shuttle cars when drum diameter meets 8 × OD (≤ 5 kV) or 12 × OD (8–25 kV).
Multi-layer winding on cylindrical reels requires ICEA S-75-381 ampacity derating factors to prevent thermal build-up.
Ask engineeringUsed for flexible jumper drops at pit substations; specify Type MP-GC for stationary borehole, shaft or duct feeders.
Type MP-GC mine power feeder90 °C wet/dry EPR insulation and extra-heavy-duty CPE jacket withstand wet benches, mud, slurry and mine dewatering duty.
Flexible unarmoured trailing construction — do not suspend in deep vertical mine shafts without support.
Use BS 6708 Type 20/21 ArmouredConstruction
Each of the three phase conductors is individually screened with semiconductive layers and a tinned-copper/textile composite braid shield, then cabled with two bare grounding conductors in direct contact with the shields and one yellow insulated ground-check pilot.
