1/0 3C Type G-GC Mining Cable 2kV

1/0 3C Type G-GC 2000V Mining Cable W/ Dual Grounds & Ground Check is engineered for rugged underground and open-pit mining environments. It delivers continuous trailing power to heavy mobile equipment without tearing, cracking, or failing under extreme drag forces.

Constructed with three flexible 1/0 AWG tinned copper conductors (266 stranding), dual #5 AWG grounds, a dedicated #8 AWG ground-check wire, and a nylon-reinforced CPE jacket, it absorbs severe impact, oil, and rock abrasion across operating temperatures from -40°C to +90°C.

Key Features & Benefits

• Fail-Safe Ground Check Conductor: Features a dedicated yellow PP-insulated #8 AWG ground check wire that integrates with monitoring relays to instantly trip circuit breakers if ground continuity breaks.

• High-Flex Tinned Copper Stranding: Built with 266 strands of soft-drawn tinned copper for exceptional flexibility, extended flex life, and superior protection against wire fatigue under continuous dragging.

• Extreme Mechanical Durability: Reinforced with an internal open nylon braid and extra heavy-duty CPE compound to deliver outstanding impact, crush, tear, and severe rock abrasion resistance.

• All-Weather & Chemical Resistance: Highly resistant to oil, grease, water, ozone, chemicals, and direct sunlight/UV exposure, ensuring reliable performance in harsh outdoor and underground environments.

• High-Dielectric EPR Insulation: Ethylene-Propylene Rubber (EPR) insulation maintains superior thermal stability, dielectric strength, and flame resistance under continuous 2000V operating loads.
