Portable Mining Cables
Type SHD-GC2 kV Shielded Portable Mining Cable
Type SHD-GC is a round, heavy-duty shielded mining trailing cable for mobile, reeling, and relocatable power systems. A typical construction combines three individually shielded 90°C EPR-insulated copper power conductors, two grounding conductors, and one insulated ground-check conductor within an extra-heavy-duty reinforced mining jacket; the ground-check circuit supports continuous monitoring of equipment-ground continuity. Common voltage classes run from 2 kV to 15 kV, and this page covers the 2 kV class. Exact dimensions, ampacity, jacket compound, bend radius, and approvals follow the selected model.

Before you quote
Clear the questions that hold up your quote.
Short answers for engineering and procurement. The reviewed quotation and its document list govern the final supply scope.
What is Type SHD-GC cable?
Type SHD-GC is a heavy-duty shielded mining trailing cable for mobile and relocatable medium-voltage power. A typical construction contains three individually shielded power conductors, two grounding conductors, and one insulated ground-check conductor.
What does the ground-check conductor do?
The ground-check conductor is used by a ground-monitoring system to verify continuity of the equipment grounding circuit and support safe shutdown if the grounding path is interrupted.
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.
