Type Shd-Gc, Mining Cable, Cu/Epr/CPE, 3/C, 2kv (ICEA S-75-381/NEMA WC-58)

Application
For use with Bretby type cable handling devices on longwall machines and as Trailing cable on ac mining equipment where a ground check conductor is required for fail-safe ground monitoring. For use where induce voltages in grounding system will not produce a hazard. This cable is designed for use on low and medium voltage AC circuits where shielding is desired or required.

Standards
