NTMCGCWÖU Single-Core Medium-Voltage Cable
NTMCGCWÖU cable is a flexible, screened single-core rubber cable for short medium-voltage connections in mines, mobile transformer substations, switchgear and heavy industrial power systems. International specifications may write the same designation as NTMCGCWOEU or NTMCGCWOU when the “Ö” character is unavailable.
The cable combines a Class 5 stranded tinned-copper conductor, semiconductive electrical-field-control layers, EPR type 3GI3 insulation, a tinned-copper wire screen and a red 5GM3 thermosetting sheath. Select the 3.6/6 kV, 6/10 kV, 12/20 kV or 18/30 kV construction to match the circuit. Each voltage group has its own dimension table covering 1×16/16 mm² through 1×185/25 mm², with insulation and jacket thicknesses, approximate diameter and weight, and current ratings at 30°C in air.
NTMCGCWÖU is intended for short flexible links and connection work, not automatically for continuous drum reeling. Selection requires system voltage, conductor cross-section, screen size and bonding method, route length, bending radius, installation mode, short-circuit duty, ambient conditions and required standards. Final ampacity, diameter and weight must be confirmed on the order datasheet. For dynamic movement, compare the R-(N)TSCGEWÖU reeling cable or send the installation drawing through the engineering enquiry form.
NTMCGCWÖU Cable Construction
| Layer | Construction | Selection purpose |
|---|---|---|
| Conductor | Annealed flexible stranded tin-coated copper, Class 5 to IEC 60228 and HD 383 | Supports flexible installation and conductor surface protection. |
| Conductor screen | Semiconductive tape and layer between conductor and insulation | Controls electrical stress at the conductor-insulation interface. |
| Insulation | EPR type 3GI3 to DIN VDE 0207 Part 20 | Provides the dielectric layer for the selected MV class. |
| Insulation screen | Semiconductive layer over insulation | Controls the outer insulation interface. |
| Metallic screen | Warp or braid of tinned-copper wires; 16 mm² or 25 mm² in the listed size range | Provides the metallic screen and fault-current path defined by the system design. |
| Separator | Synthetic tape wrap | Separates the screened core from the outer jacket. |
| Outer sheath | Red synthetic thermosetting compound type 5GM3 to DIN VDE 0207 Part 21; other colours available | External mechanical and environmental protection. |
The screen cross-section, insulation and jacket thicknesses, and completed diameter depend on the selected voltage and conductor size. Confirm all layer dimensions on the quotation drawing.
Applications and Cable-Type Boundaries
- Connections between mobile transformers, substations and overhead lines.
- Medium-voltage switchgear cubicle connections.
- Mining and industrial power distribution requiring a flexible screened single-core cable.
When another cable is required
Use a dedicated reeling cable for continuous drum winding, repeated high-speed movement or tightly controlled S-bend routes. Use a multicore mine-distribution cable when the circuit requires three phase cores, earth, control or monitoring elements in one construction. Useful alternatives include (N)TSCGEWÖU mine-distribution cable and (N)TMCETMPU portable trailing cable.
RFQ data
Provide system voltage, conductor and screen cross-sections, current and fault duty, route length, termination and bonding arrangement, minimum bend radius, installation temperature, oil/UV/moisture exposure, drum length and required test documentation.
