Portable Mining Cables
Type G-GC2 kV Portable Mining Power Cable
Type G-GC is a round, heavy-duty, normally non-shielded 2,000 V portable power and mining cable. A typical construction combines three flexible copper power conductors, 90°C EPR/EPDM insulation, two integral grounding conductors, and one insulated ground-check conductor within a rugged thermoset mining jacket. It serves mobile mining and severe industrial equipment where equipment grounding and continuous ground-continuity monitoring are required. Exact dimensions, ampacity, conductor coating, jacket compound, wet rating, and approvals follow the selected model.

What is Type G-GC cable?
Type G-GC is a heavy-duty, normally non-shielded 2,000 V portable power and mining cable. A typical round construction contains three power conductors, two grounding conductors, and one insulated ground-check conductor.
What does the ground-check conductor do?
When connected to a compatible ground-monitoring system, the ground-check conductor supports continuous verification of the equipment-grounding circuit. The complete monitoring and trip system determines the safety function.
What is the minimum order quantity?
MOQ depends on conductor size, construction, production batch, and reel length. Send the required size and total length; the quotation will state the applicable minimum quantity and packaging basis.
How quickly can the cable be delivered?
Lead time varies with material availability, construction, quantity, document scope, and destination. After the specification is reviewed, the quotation will provide a production window and an indicative shipment schedule.
How are destination-market standards and documents reviewed?
Tell us the destination market, governing standard, and end-user document requirements. They are reviewed against the selected product and available product documents; applicability is confirmed in the quotation.
Can length, sheath colour, printing, or packaging be customized?
These options can be reviewed subject to engineering suitability, regulatory requirements, MOQ, and production capability. Any approved change is recorded in the quoted specification, drawing, or order document.
