The nominal outer diameter of a Type SHD-GC 3/C 350 MCM 15kV flexible mining trailing cable is approximately 73 mm (2.87 inches), with a maximum permissible outer diameter of approximately 74.9 mm (2.95 inches) per ICEA S-75-381 and NEMA WC-58 standards. The approximate weight of this specific cable geometry is 10,900 kg/km (7,300 lbs/1000 ft). It features three 350 MCM (177 mm² equivalent) main power conductors rated for 435 amperes continuous operation, supplemented by two 2/0 AWG earth conductors and one 6 AWG ground-check monitoring conductor for enhanced mining safety systems. The distinction between nominal (design target) and maximum (allowable limit) outer diameter is critical for mining operations because reel systems, conduit systems, and terminal connectors are engineered based on these dimensional constraints. A cable that exceeds the maximum outer diameter will not fit into equipment designed for the nominal specification, creating logistics delays and operational disruptions that cost far more than any cable savings.

8.7/15kV voltage rating is classified under Medium Voltage (MV), supporting heavy-duty equipment power and MV distribution on industrial sites, mining operations, and utility networks. 15kV is a voltage commonly specified for equipment cables, including robust mining equipment cables manufactured in accordance with IEC 60502-2, but is also associated with British standard armoured cables BS6622 and BS7835.

What is 8.7/15kV Cable?

mining cables may be sheathed in robust rubber to provide abrasion resistance, especially for trailing applications, the BS6622 and BS7835 standard cables are instead sheathed in PVC or LSZH materials, with mechanical protection provided from a layer of steel wire armouring. As a British standard voltage, 8.7/15kV isn’t as commonly specified as 11kV or 33kV, but will depend on the application demands.
