Application fit

Is WK 300w-Torsion 1.8/3 kV right for your machine?

Free-hanging vertical run

Suitable

Class 5 flexible copper cores and cross-linked EPR / silicone / PCP rubber jackets survive >10,000–18,000 yaw drip-loop torsion cycles.

Fixed installation

Suitable

Routes continuously from nacelle generators and yaw/pitch cabinets through the free-hanging drip loop into upper tower trays.

Offshore platform & shipboard deck trays

Suitable

Polychloroprene (CR/PCP), CPE, silicone (FDGG) and PUR (FDGU) sheaths resist hydraulic oil, grease, ozone, salt spray and −40 to −55 °C co

VFD inverter to AC motor screened feeder

Suitable

Copper-braid screened variants (FDEFP, FDEHP, WINDLINK WTTC) contain PWM converter electromagnetic interference along the drip loop.

Festoon & line chain

Not suitable

Wind turbine vertical torsion rubber cable is optimized for axial twist rather than high-speed trolley festoons.
