Nexans to supply 23 km of 35 kV submarine cables for the Arklow Bank Wind Farm in Ireland.

About the project

Nexans has been awarded an order for the supply of 23 km of 35 kV submarine power cables to transport the power generated by the wind turbines of the Arklow (Ireland) wind farm to an onshore cable station, as well as the links between the individual wind turbines.

The wind farm, which has 7 wind turbines, each with a capacity of 3.6 MW, is located in the Irish Sea on a sandbank south of Dublin. The wind turbines were installed by GE Wind Energy. In the project's final stage, it could have up to 200 wind turbines.

Nexans' solutions

The cables, with a cross-section of 3 x 1 x 300 mm2 and an outside diameter of 125 mm, are among the largest submarine cables manufactured in the Nexans Hanover plant.

The laying up of a total number of 24 optical fibers for data transmission in the Gbit range between onshore facilities and wind power plants, was another achievement. With optical fibers from Nexans in Norway, specially developed for harsh offshore environments, all wind turbines can be individually controlled from onshore.
