Flexible power supply cable for use in underground mining facilities especially for festoon systems. Cables classified according to EN 50575 (CPR).
Cable Design
Conductor : finely stranded class 5 (EN 60228, DIN VDE 0295) tinned, electrolytic copper
Control/protective conductor : spirally applied concentric CuSn wires forming control conductors around support element, EPR insulation and spirally applied concentric CuSn wires to form protective conductor
Insulation : EPR compound with improved electrical and mechanical characteristics (DIN VDE 0207, Part 20)
Electrical field control : inner and outer layers of semiconductive rubber
Core identification : natural colouring with black semiconductive rubber with printed white digits 1-3
Core arrangement : three power conductors laid-up with double concentric control/protective conductor elements in the outer interstices, with optimised lay length
Inner sheath : GM1b (acc. to DIN VDE 0207, Part 21)
Signal/monitoring conductor : spirally applied FeZn and CuSn wires in a vulcanized bond between inner and outer sheath.
Outer sheath : 5GM5 compound with improved mechanical characteristics (acc. to DIN VDE 0207, Part 21), colour: red
