Nexans to supply cables for the world's first 66 kV offshore wind farm.

About the project

The Blyth Offshore Demonstrator Wind Farm Project, located 5.7 km off the port of Blyth in Northumberland (UK), consists of three arrays with five wind turbine generators each. A 66 kV inter-array cable network and separate export cables will carry the energy onshore. Nexans cable technology has been selected by VBMS for the world’s first 66 kV offshore wind farm.

Nexans' solutions

As part of its own contract with EDF Renewables, VBMS will use the Nexans 66 kV inter-array cable system to provide the subsea connection between the offshore turbines and the onshore grid for the Blyth Offshore Demonstrator Wind Farm Project. With offshore wind turbines growing in size, the new 66 kV Nexans technology is improving the lifecycle cost-efficiency compared to 33 kV systems.

The 66kV subsea cable will be manufactured and tested at Nexans’ specialist factory in Hanover, Germany, before it is supplied in one length in 2017. The related connectors will be manufactured by Nexans Power Accessories in Erembodegem, Belgium, and have been developed from the well-established 33 kV technology.
