Nexans will supply over 200 km of 245 kV cross-linked polyethylene insulated (XLPE) near-shore export cables.
Located in the North Sea off the Yorkshire coast, the 1.4 GW windfarm will be the world’s largest once it starts operating, which is scheduled for 2022.
Nexans three-core HVAC submarine cables will bring the electricity onshore. The 245 kV XLPE cables will be part of the near-shore section of the export circuits linking the windfarm’s reactive power substation to the onshore substation.
The circuits will comprise three individual near-shore export cables and will follow a similar route to sister windfarm Hornsea 1, which Nexans Norway supplied with 139 km of three-phase 36 kV subsea cable inter-linking a total of 58 wind turbines and connecting them to the offshore transformer station.
The route will make landfall at Horseshoe Point from where land cables will feed the power to North Killingholme onshore substation.
