Type SHD-GC Power, Shielded Round Portable W/Ground-Check | EPR/CPE 2-25kV Mining Cable

Product Overview

Type SHD-GC Power Cable is a shielded, round portable cable engineered for high-voltage trailing applications in mining and heavy industrial environments. Rated for 2kV to 25kV and 90°C operation, it features ethylene propylene rubber (EPR) insulation, a reinforced CPE jacket, and integrated ground-check monitoring. Compliant with ICEA S-75-381 and MSHA standards, this cable delivers exceptional resistance to oil, chemicals, abrasion, and flame, ensuring safe power transmission for longwall shearers, AC mining equipment, and other high-risk applications.


Key Features

  • Fail-Safe Ground-Check System: Integrated yellow polypropylene-insulated ground-check conductor for real-time safety monitoring.

  • High Voltage Capacity: Rated for 2kV to 25kV systems with shielded design to mitigate induced voltages.

  • Robust Shielding: Flexible copper/textile braid shield over non-conductive tape for EMI and shock hazard protection.

  • Mining-Grade Durability: Dual-layer CPE jacket resists cuts, oil, steam, and radiation.

  • MSHA Compliance: Meets flame test requirements for hazardous mining environments.
