Product Overview
Type SHD-GC Power Cable is a shielded, round portable cable engineered for high-voltage trailing applications in mining and heavy industrial environments. Rated for 2kV to 25kV and 90°C operation, it features ethylene propylene rubber (EPR) insulation, a reinforced CPE jacket, and integrated ground-check monitoring. Compliant with ICEA S-75-381 and MSHA standards, this cable delivers exceptional resistance to oil, chemicals, abrasion, and flame, ensuring safe power transmission for longwall shearers, AC mining equipment, and other high-risk applications.
