A wind turbine cable is a moving cable. The loop between nacelle and tower twists every time the machine yaws, and the pitch system twists in both directions for the life of the turbine. ZMS builds torsion-resistant constructions with fine-strand Class 5 or 6 copper, an EPR or XLPE insulation and a PUR or PCP sheath that resists abrasion and low-temperature cracking.
Product pages include the full construction table, options and applications.
Multi-core power and control cable built for repeated twisting in nacelle and tower runs.

Typical construction data. Final values are confirmed on the order-specific datasheet.
We can adapt this family to the project requirements. Common options include:
Nacelle cable is twisted each time the turbine yaws. The conductor stranding, the core lay and the sheath compound are selected together so the cable keeps its electrical integrity through repeated torsion cycles at low ambient temperature.
The wind turbine cables selection guide covers voltage rating, conductor class, screen and sheath options, drum length and the test reports issued with each delivery.

The right construction depends on voltage, movement and the environment along the route.
The twisted loop that follows yaw movement and carries power and control between nacelle and base.
Rotating blade root wiring that sees the highest torsion count in the turbine.
Cable inside the hub and yaw deck, exposed to vibration, oil and temperature extremes.
