Type G-GC Mining Cable – 3 Conductor Flat Parallel w/Ground-Check | 2000V EPR/CPE | MSHA Approved | 6AWG-500kcmil

Product Overview

Type G-GC (SHD-GC) Portable Mining Cable delivers 2000V power transmission for extreme mining environments. Featuring flat parallel construction with integrated ground-check monitoring, EPR insulation, and heavy-duty CPE jacket, it meets MSHA/ICEA S-75-381 for trailing applications in mines. Rated for 90°C operation with unmatched crush/abrasion resistance.

Core Construction

  1. Conductor System:

    • Power Conductors (3): Rope-lay-stranded coated copper (6AWG to 500kcmil; ASTM B172)
