Application:
Mines and Quarries power cable manufactured to BS5467 and BC295 Mines and Quarries regulations. The hazard resistant cable is designed for use in extreme applications and environments where long service is required from the cable. The 1.9/3.3kV cable is available in sizes from 10mm² to 300mm², the cable features plain copper conductors, XLPE insulation, extruded PVC bedding, galvanised steel wire armouring incorporating tinned copper wires to provide 60% conductivity of any one phase, black PVC outer sheath.
For installations that require a lower working voltage 600/1000V BS5467 and BC295 cable maybe a preferred option.
