Before ordering, confirm the exact product variant, conductor or core arrangement, system rating, route conditions, equipment connection and required documentation against the project specification. The requested (N)TSCGECWÖU – TBM Medium Voltage Cable for Tunnel Boring Machines should be evaluated as a complete cable assembly: review its intended equipment, conductor arrangement, installation method, movement duty, environment, terminations, dimensions and required documentation together. The V2 layout keeps the source-listed construction, application, technical and standard information available for a controlled engineering and procurement review. Use the Request Quote section to confirm the exact configuration, route conditions and documentation requirements before production or replacement ordering.
(N)TSCGECWÖU - TBM Medium Voltage Cable for Tunnel Boring Machines construction
Cable Construction
- Conductors: Flexible tinned electrolytic copper conductor, DIN VDE 0295 class 5.
- Insulation: 3GI3 type EPR compound for medium voltage operation.
- Electrical field control: Inner and outer semiconductive rubber layers.
- Control cores: Tinned copper conductors with semiconductive layer.
- Protective earth conductor: Tinned copper and textile braiding combined cores laid concentrically around each power core.
- Core identification: Main cores in natural color with black semiconductive rubber; control cores in black.
- Lay-up: Three main conductors laid up with three control cores in the outer interstices.
- Inner sheath: GM1b type EPR compound.
- Overall concentric screen: Overall concentric layer of copper wire spinning.
- Outer sheath: 5GM5 type elastomer compound, red.
Reference family: TENAX-H and TENAX-HP construction compared
Enquiries for this cable often arrive quoting the TENAX-H and TENAX-HP reference designations. In that reference family the layer sequence differs from a plain screened trailing cable in two ways worth checking against your specification, because both affect the earthing and monitoring interface rather than the current rating.
| Element | Reference-family arrangement | Why it matters on selection |
|---|---|---|
| Earth conductor | Spiral of tinned copper wires applied over the outer semi-conductive layer of the cores | Sits on the cores themselves, not as a single overall layer; determines how each phase is earthed. |
| Monitoring shield | Conductive rubberized textile tape together with a spiral of copper and steel wires, applied over the inner sheath | A separate element from the earth conductor. The copper-steel mix, rather than plain copper, is what the reference family specifies. |
| Intermediate sheath | GM1b rubber compound of high mechanical strength, between the monitoring shield and the outer sheath | An additional sheath the unarmoured build carries beneath the overall sheath. |
| Armour | None on NTSCGECWOEU. NTSCGECCWOEU adds a braided armour of galvanised steel wires below the outer sheath, which also forms an external earthed shield | The armoured build is a separate designation with two C positions, not a variant of this one. |
| Supply form | Matched lengths, typically 100 m or 200 m, both ends fitted with terminations adapted to the high-voltage connection box entry fitting | Terminations are made to the equipment box, so the box type is stated with the order. |
| Bending radius | 4 × D static; 7.5 × D for operation-related transport, installation and mobile application | Reference-family figures; compare against the route values tabulated for this product. |
This comparison is given so that a reference designation can be matched layer by layer. It does not state that this product and the reference family are equivalent: the construction and dimensional data supplied for this cable are those tabulated in the Construction and Specifications sections above. For the armoured build with the additional galvanised steel wire braid see NTSCGECCWOEU armoured monitored mining cable, and for the separate-earth monitoring construction at 8.7/15 and 12/20 kV see (N)TSCGECECWÖU TBM reeling cable.
Reference note: for enquiries marked TENAX-H or NTSCGECWOEU, TEBAOFLEX manufactures to the (N)TSCGECWÖU designation and the construction shown, and is not affiliated with the trademark holder.
(N)TSCGECWÖU - TBM Medium Voltage Cable for Tunnel Boring Machines applications
Applications
- Power supply cable for tunnel boring machines.

- Heavy-duty cable systems requiring flame retardance, oil resistance and mechanical flexibility.
- Project installations where cable diameter, weight, tensile load and bending behavior must be checked before supply.
Selection checks
Confirm the equipment interface, installation method, route length, movement or flexing duty, environmental exposure, conductor or core requirements and project documentation before final selection.
Reference designation cross-reference
This monitored TBM cable is catalogued under two reference names that differ only in whether an armour is present.
| Reference designation | TEBAOFLEX designation and build | Rated voltage | What the reference name marks |
|---|---|---|---|
| TENAX-H / NTSCGECWOEU | (N)TSCGECWÖU monitored TBM reeling cable | 3.6/6 to 18/30 kV | The unarmoured monitored build shown on this page |
| TENAX-HP / NTSCGECCWOEU | NTSCGECCWOEU armoured monitored mining cable | 3.6/6 to 6/10 kV | Adds the tinned steel wire braid armour; see the armoured page |
For the counterpart construction see NTSCGECCWOEU armoured monitored mining cable.
For the full list of reference designations and the TEBAOFLEX build each one maps to, see the mining cable designation cross-reference.
Trademark note: TENAX®, TROMMELFLEX®, FELTOFLEX® and SCHRÄM® are trademarks of their respective owners, and TEBAOFLEX is neither affiliated with those companies nor reselling their cable. What we supply is the equivalent construction: we manufacture to the same VDE type designation and published construction, and every designation listed here can be quoted and supplied as a TEBAOFLEX build. The names appear for identification only; the matching construction is made to the standards and construction confirmed for the order.
