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.
