Type Shd-Gc, Mining Cable, Cu/Epr/CPE, 3/C, 15kv (ICEA S-75-381/NEMA WC-58)

Features
Meets all requirements of ICEA S-75-381. Reformulated compounds suitable for CV curing, developed to meet the high level of physical properties required in service.

Application

Trailing cable on ac mining equipment where service conditions are severe and maximum safety is mandatory; such as power shovels and drag lines in open-pit mines, quarries, gantry cranes and slag reclaiming. Used for high voltage distribution in underground mines where frequent relocation is necessary or where extra flexibility and toughness is desired.

Standards
