(N)TSCGEWOEU Cable for Tunnel Boring Machine Reeling Systems

(N)TSCGEWOEU cable is a medium-voltage flexible reeling cable designed for tunnel boring machines and heavy tunneling equipment. In TBM operation, the cable must deliver reliable power while moving through cable drums, guiding systems and changing tunnel routes. This product is built for reeling power supply in underground mines and tunnel construction sites where bending, torsion, tensile load, moisture, oil exposure and mechanical stress are daily operating conditions.

The cable construction combines Class 5 finely stranded tinned copper conductors, EPR insulation, semiconductive electrical field control, copper/textile mixed braid protective conductors, control cores, monitoring conductor, GM1B inner sheath and a red 5GM5 synthetic elastomer outer sheath. This gives engineers a cable structure that supports both electrical performance and mechanical endurance in TBM power supply routes.

Key Features

  • Designed for TBM reeling power: Suitable for tunnel boring machines and tunnel construction equipment where the power cable is repeatedly reeled, unreeled and guided along the machine route.
  • Medium-voltage project range: Supports project selection across 6/10 kV, 8.7/15 kV, 12/20 kV, 14/25 kV and 18/30 kV voltage classes.
  • Flexible tinned copper conductor: Class 5 finely stranded tinned copper supports flexible movement and helps protect conductor surfaces in underground environments.
  • Electrical field control: Inner and outer semiconductive rubber layers help manage electrical stress in MV operation.
  • Protective conductor on each core: A single concentric copper/textile mixed braid over every core supports protective conductor function and cable integrity.
  • Monitoring conductor design: Overall concentric copper wire spinning helps support monitoring and fault supervision in tunneling power systems.
  • Rugged elastomer sheath system: GM1B inner sheath and 5GM5 red synthetic elastomer outer sheath support oil, weather, ozone and moisture resistance.
  • Built for movement limits: Suitable for reeling and TBM operation when tensile load, torsional stress, bending radius, directional changes and travel speed are correctly reviewed.

Selection Notes for TBM Projects

When specifying (N)TSCGEWOEU cable, confirm voltage class, TBM travel speed, cable drum dimensions, route direction changes, tensile load, torsion exposure, control core requirements, monitoring conductor connection and current carrying capacity. In TBM service, the cable should be selected as part of the machine movement system, not only as a static power feeder.
