Flexible power supply cable for use in underground mining facilities for mobile machines like coal cutters etc. Designed for use in cable chains trailed behind the machines. Chains have protective function and absorb the tensile forces occuring during operation.
Cable Design
Conductor : finely stranded class 6 (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
