Product Overview: (N)TMCGCWOEU (German designation (N)TMCGCWÖU, referencing DIN VDE 0250-813) is a flexible, screened single-core medium-voltage rubber cable spanning 3.6/6 kV, 6/10 kV, 12/20 kV, and 18/30 kV for mobile mining substations, MV switchgear jumpers, transformer interconnections, and heavy industrial MV drives.
1. Application & Medium-Voltage Duty Scope
Where rigid XLPE MV distribution cables cannot accommodate tight switchgear bends, vibration, or equipment relocation, screened single-core (N)TMCGCWOEU provides elastomeric flexibility with full radial electric-field control:
- Mining & Tunnelling Substations: Flexible single-core phase connections between skid-mounted transformers, MV circuit breakers, and power centres.
- Switchgear, Containerized E-Houses & Drives: Short-radius MV busbar jumpers, generator leads, and large MV VFD/motor terminations.
- Relocatable Industrial MV Feeders: Trefoil or flat single-core runs requiring matched MV stress-cone terminations and metallic screen earthing (confirm any trailing, energy-chain, or reeling motion separately).
Related Medium-Voltage Options: Need a polyurethane (PUR) outer sheath for severe cut/abrasion exposure? Compare (N)TMCGCW11Y PUR Medium-Voltage Cable. For 3-core ground-check trailing up to 25 kV, see Type SHD-GC Mining Trailing Cable, or review our Mining Cable Application Guide.
2. Cable Construction (6-Layer MV Field-Control Anatomy)
Every medium-voltage (N)TMCGCWOEU build integrates radial dielectric stress control between the Class 5 conductor and concentric earth screen (final layer thicknesses and screen cross-sections are governed by the approved order drawing):

Specify both the phase conductor cross-section and the concentric copper screen cross-section (e.g., 1 × 95/16 mm² or 1 × 150/25 mm²) against your system fault calculation:

5. Frequently Asked Questions
Is (N)TMCGCWOEU a single-core or three-core medium-voltage cable?
(N)TMCGCWOEU is a screened single-core MV rubber cable. Specify both phase conductor size and concentric copper screen size (for example, 1 × 120/16 mm²) for each phase run.
Can the 10 × OD moving bend radius be used automatically for continuous drum reeling?
No. Range guidance applies to standard flexible routing. Continuous trailing, festoon, or drum reeling requires engineering review of drum barrel diameter, speed, tension, and sheath/screen fatigue.
When should I compare (N)TMCGCW11Y or TRM-J?
Compare (N)TMCGCW11Y when a polyurethane (PUR) outer jacket is needed for extreme surface abrasion, or TRM-J 0.69/1.15 kV for multi-core low-voltage screened mining circuits.
Does every configuration carry third-party VDE or UL certification?
No blanket product mark is claimed across every voltage and cross-section—DIN VDE 0250-813 serves as the construction reference. State any mandatory routine test, HV partial-discharge test, or destination approval on your inquiry.
How should the metallic screen be terminated?
Use MV indoor/outdoor heat-shrink or cold-shrink stress-control terminations matched to the exact insulation OD, and bond the copper screen according to single-point or both-ends earthing calculations.
What project details are needed for an accurate quotation?
Send nominal/max system voltage, phase and screen cross-sections (mm²), short-circuit current/duration, installation mode (fixed, trefoil, relocatable, or dynamic), ambient environment, cut lengths, and required inspection documents (browse more in Mining & Tunneling Cables).
