NTSKCGERLOEU Medium Voltage Coal Cutter Cable

Applications

These cables are used for the connection of mobile electrical equipment in underground mines, e.g. for coal-cutting machines, especially for the use in bretby chains with extreme bending loads under low tensile stress.

Standards

VDE 0250 Part 813

Construction

NTSKCGERLOEU Medium Voltage Coal Cutter Cable
Conductors Flexible stranded tinned copper conductor.
Insulation Heat resistant 3GI3 rubber based on EPR.
Outer Conductor Layer (for 3.6/6kV) Easy strippable outer conductive layer.
Pilot Cores Copper/steel conductor capable of expansion and compression with EPR rubber insulation.
Earth Conductor Spiral of tinned copper wires and a conductive tape.
Inner Sheath 2 layer design, semi conductive rubber + Rubber type 5GM5.
Armour Spiral of steel wires, embedded in the outer sheath, fiberglas tape which prevents sheath exchanging.
Outer Sheath Rubber type 5GM5, abrasion and tear resistant, oil resistant and flame retardant.
