Nkt will provide four 132kV, high-voltage cables for the facility off the coast of north Wales, which will have a capacity of 576MW once operational.
The cables will transmit energy produced by the site's 160 Siemens turbines to the coast, where the closest feeding point is St Asaph.
Gwynt y Môr is a Round 2 project being developed by RWE Innogy and Munich-based German utility Stadtwerke
