Product overview

NTSKCGECWOEU is a medium-voltage coal-cutter chain cable for underground mobile mining equipment, coal-cutting machines, cable protection chains and trailing cable handlers. The supplied VDE datasheet specifies finely stranded tinned copper conductors, 3GI3 EPR insulation, cold-strippable semiconductive field control, double concentric control and PE wire elements, a GM1B inner sheath, closed-lay steel and copper wire protection and a red 5GM5 synthetic elastomer outer sheath. The technical tables cover 1.8/3 kV and 3.6/6 kV systems, with three-control and six-control arrangements and conductor configurations from 25 mm² through 240 mm². The source lists 90 °C conductor operation, 250 °C short-circuit temperature, fixed service from −40 °C to +90 °C and fully flexible service from −20 °C to +90 °C. Chain geometry, movement cycles, tensile path, bending radius, core functions, UEL notation and termination hardware must be checked against the machine drawing. Use the size table together with the machine duty cycle and installation layout; cable selection should be approved against the chain travel, support spacing and connector system. Request the required configuration, size, length and test documents from TEBAOFLEX before release.

Construction

NTSKCGECWOEU chain-cable construction

This construction combines three main power cores with double concentric control and PE conductor elements. The cable uses a finely stranded tinned-copper conductor, 3GI3 EPR insulation, an inner GM1B sheath, closed-lay steel/copper wire armouring and a red 5GM5 elastomer outer sheath.

The chain-protection route and the double-concentric control/PE arrangement are the key ordering distinctions. Keep the source core notation in the RFQ and verify the termination hardware against the final cable drawing.

Applications

Applications for NTSKCGECWOEU

The source describes a power-supply connection cable for mobile equipment and machines in underground mining, including coal-cutting machines. It is intended for cable protection chains and cable handlers trailed behind the machine, where repeated movement and tensile forces must be absorbed.

  • Underground coal-cutting machines and other mobile mining equipment listed in the source
  • Cable protection chains and cable handlers trailed behind the machine
  • 1.8/3 kV and 3.6/6 kV systems with three- or six-control-core table options
  • Confirm chain geometry, movement cycle, tensile path, bend radius, core functions, terminations and protection interface before quotation

The supplied bending and tensile values describe the cable construction; they do not replace the machine-specific chain calculation or the approved installation drawing.
