series G GC
Three-conductor
Reelable flexible cables for mining use
This type of cable is required for extra-heavy duty industrial use. Designed for applications such as longwall shearers, continuous miners, loaders, drills, conveyors, pumps and mobile equipment; both in open pit mining and underground mines and similar applications. Suitable for applications where grounding conductors (G) and ground check conductors (GC) are needed
