Medium-voltage cables

Windfarms MV

  • Onshore, underground single-core cables (33 kV) connect the strings of wind turbines, linking them in parallel to the substation.
  • 24 kV and 36 kV “smart cabling solutions” are available: TSLF-O, TSLF-OJ, TSLF-J twisted cables, and TSLF-O and TSLF-J singlecore.
  • Cost-efficient submarine 3-core cables with integrated fiber optic elements and customized armor designs. 

We provided inter-turbine/export cables for Anholt (DK), the world’s third largest offshore wind farm.

Our two leading types of medium-voltage cable are XLPE (cross-linked polyethylene) and EPR (Ethylene Propylene Rubber). The former is used worldwide, while the latter is mainly for selected markets.

From a design point of view, medium-voltage cables are of three types:

  • single-core cable,
  • three single-core cables laid-up,
  • three-core cable.

Nexans cables are custom designed to meet your high performance standards.
