N3GHSSYCY Screened/PVC Medium Voltage Mining Cable
N3GHSSYCY Screened/PVC Medium Voltage Mining Cable Application
These N3GHSSYCY cables are used for the connection of mobile operating equipment, in mines and underground excavations with hazardous environments, if monitoring of outer damages is required in stationary operation, e.g.high-voltage transformers in mining and tunneling.
These N3GHSSYCY cables are also flexible cable for energy supply to MV mobile operating equipment in mines and underground excavations with a hazardous environment, in stationary operation e.g. high-voltage transformers in tunneling.
PVC inner sheath, control-core and additional pilot cores, steel wire braid and PVC sheath. Suitable for indoor and outdoor applications.
