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
| 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. |
