(N)TMCHXOEU 12/20 kV LSOH Single-Core Wind Turbine Cable
(N)TMCHXOEU 12/20 kV single-core LSOH wind turbine cable reference with Class 5 bare copper, EPR-3GI3 insulation, a spiral tinned-copper screen and black HXM1 rubber sheath.
(N)TMCHXOEU 12/20 kV is a single-core screened cable designation for wind-turbine medium-voltage connections subject to medium mechanical stress. The supplied reference shows three single-core sizes rather than a multicore tower cable. Use it when the electrical design calls for a separate phase cable and the routing, support and screen-bonding arrangement are defined at system level.
Its catalogue construction pairs fine-stranded Class 5 bare copper with EPR-3GI3 rubber insulation, inner and outer semiconductive field-control layers, a spiral layer of tinned-copper screen wires and a black vulcanized HXM1 outer sheath. The source identifies the series as low-smoke, zero-halogen (LSOH) and gives a fixed-installation ambient range of −40°C to +80°C; for fully flexible operation, the lower ambient bound is −25°C. The size table reports minimum bend radius separately for fixed and free-moving service.
Specify the voltage, phase size, screen cross-section, single-core arrangement, bonding design, cable support and movement before asking for a quotation. The source-listed 1×50/16, 1×120/16 and 1×150/25 mm² configurations are separate from the multicore (N)TSCGEHXOEU wind turbine cable. If the turbine requires 36/60–69 kV, review the high-voltage model instead. The industrial cable range gives the wider selection context.
Construction
The single-core design uses a fine-stranded bare-copper conductor and EPR-3GI3 rubber insulation between semiconductive field-control layers. A spiral tinned-copper-wire screen surrounds the insulated core, and a black HXM1 vulcanized rubber outer sheath completes the reference construction.

Applications
The source places (N)TMCHXOEU in wind turbines under medium mechanical stress. Size the cable for the voltage and current, then check the route for fixed or moving service: the supplied lower ambient limit is −40°C when fixed and −25°C when fully flexible. Cable cleats, screen bonding and terminations should be engineered as a single-core system.
How does it differ from (N)TSCGEHXOEU?
This (N)TMCHXOEU reference is single-core with a spiral tinned-copper screen and EPR-3GI3 insulation. The (N)TSCGEHXOEU medium-voltage wind page carries three-core and 3+3 catalogue configurations with HEPR and a different size table. Select by circuit layout and cable formation before comparing diameters or ampacities.
