Mining Cable
NTSKCGERLOEU Medium-Voltage Coal Cutter Cable
Applications
NTSKCGERLOEU Medium-Voltage Coal Cutter Cables are used for the connection of mobile electrical
equipment inunderground mines, e.g. for coal-cutting machines,especially for the use in bretby chains with
extremebending loads under low tensile stress.
Standards
VDE 0250 Part 813
Construction
Conductors:
Flexible stranded tinned copper conductor.
Insulation:
Heatresistant3GI3 rubber based on EPR.
Outer Conductor Layer (for 3.6/6kV):
Easy strippable outer conductive layer.
Pilot Cores:
Copper/steel conductor capable ofexpansion and compression with EPRrubber insulation.
Earth Conductor:
Spiral of tinnedcopper wires and a conductive tape.
InnerSheath:
2 layer design, semi conductive rubber + Rubber type 5GM5.
Armour:
Spiral of steel wires,embedded in the outer sheath, fiberglas tape which preventssheath exchanging.
Outer Sheath:
Rubber type 5GM5, abrasion and tear resistant, oil resistant and flame retardant.
