 Mining Cable
NTSCGECWOEU Medium-Voltage Coal Cutter Cable
Applications
These 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
System1 (1.8/3kV or 3.6/6kV): Flexible stranded tinned copper conductor with heatresistant3GI3 rubber based on EPR,easy strippable outer conductive layer.
System2 (0.6/1kV): Flexible stranded tinned copper conductor with heatresistant3GI3 rubber based on EPR.
Earth Conductor: Spiral of tinnedcopper.
Center Bundle: Control and pilot cores withcopper/steel conductors capable of expansion andcompression, EPR insulation,optional with fiber optics, covered with tinned copper wires semi conductive rubber sheath.
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.
