(N)TSCGEHXOEU 36/60–69 kV High-Voltage Wind Turbine Cable
(N)TSCGEHXOEU high-voltage wind turbine cable with a 36/60–69 (72.5) kV catalogue rating, HEPR insulation, Class 5 bare copper, halogen-free sheaths and four listed 3+3 configurations.
(N)TSCGEHXOEU 36/60–69 kV is a high-voltage flexible cable designation for wind turbines. The supplied reference calls this range high voltage and specifies a 36/60–69 (72.5) kV rated class; it must therefore be selected independently from 12/20 and 20/35 kV medium-voltage versions. The four published configurations use a 3+3 formation and require size-specific checks for outer diameter, handling radius and torsional allowance.
The design reference combines finely stranded Class 5 bare copper, HEPR insulation, inner and outer semiconductive layers, a halogen-free GM1b inner sheath and a black halogen-free HXM1 outer sheath. It is intended for medium mechanical effort in a wind turbine and may be installed free-moving, free-hanging or fixed; the catalogue identifies the free-hanging cable as twistable. That statement does not replace a project-specific dynamic-duty calculation for a tower loop.
A high-voltage cable selection also depends on terminations, field control, bonding, voltage class and an agreed acceptance test plan. Send the exact 3+3 configuration, route drawing, ambient range, twist requirement and required electrical documentation with the quotation request. The 12/20–20/35 kV (N)TSCGEHXOEU page contains the medium-voltage sizes. The industrial cable range provides related equipment cables.
Construction
The high-voltage reference construction combines a fine-stranded bare-copper Class 5 conductor with a clean HEPR dielectric and semiconductive conductor/insulation screens. A GM1b rubber inner sheath and black HXM1 halogen-free outer sheath protect the assembled 3+3 cable.

Confirm the metallic return, bonding and accessory interface on the released production drawing. The supplied sheet does not define one universal termination scheme for all four sizes.
Applications
The reference sheet places this cable in high-voltage wind-turbine power transmission where free-hanging, free-moving or fixed installation is required. It lists a −40°C to +80°C ambient range for fixed and fully flexible operation, and a size-specific torsional range of ±70 to ±80°/m. Coordinate the moving length and minimum bend path with the turbine OEM.
Why it is a separate high-voltage selection
The 36/60–69 (72.5) kV rating, 90 kV main-core AC test reference and 10–10.5 mm insulation values differ from the lower-voltage (N)TSCGEHXOEU tables. Match the voltage and accessory design first; do not substitute a similarly named 20/35 kV cable based on conductor area alone.

Current ratings are reference values for free air at 30°C according to IEC 60364-5-52 Table B.52.12. Apply the project installation and grouping factors. The values are from the supplied catalogue edition and require confirmation against the TEBAOFLEX production drawing.
Standards
The supplied high-voltage reference identifies its design as based on IEC 60840 and DIN VDE 0250-813. IEC 60228 / DIN VDE 0295 is the Class 5 conductor reference. The selected order specification must define which standard and acceptance test clauses apply to the actual cable and accessories.

| Smoke emission | IEC 61034-2 referenced |
| Flame propagation | IEC 60332-1-2 referenced |
| Oil resistance | IEC 60811-404 test reference |
| Ozone resistance | DIN EN 50396, clause 8.1.3 referenced |
