NTSCGECWOEU 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

NTSCGECWOEU Medium Voltage Coal Cutter Cable
System1 (1.8/3kV or 3.6/6kV) Flexible stranded tinned copper conductor with heat resistant 3GI3 rubber based on EPR, easy strippable outer conductive layer.
System2 (0.6/1kV) Flexible stranded tinned copper conductor with heat resistant 3GI3 rubber based on EPR.
Earth Conductor Spiral of tinned copper.
Center Bundle Control and pilot cores with copper/steel conductors capable of expansion and compression, EPR insulation, optional with fiber optics, covered with tinned copper wires semi conductive rubber sheath.
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.
