Global technology company ABB is to install 40 special transformers to the western part of MHI Vestas Offshore’s Walney Extension windfarm in the Irish Sea.
The facility is 19km west of Walney Island off the coast of Cumbria in England. Its turbines are 195m tall and weigh 1,000mt, with its 80m rotor blades capable of generating up to 8MW of power.
Owned by the Danish utility DONG Energy, the Walney Extension will be able to provide additional generation capacity of 660MW, along with its existing 367MW. Of the additions, the western side will account for 330MW.
ABB Power Grids Division president Claudio Facchin said: "These transformers are specially designed to meet the specific application needs of the most powerful wind turbines and are testimony to ABB’s technology and innovation. This strength is a key differentiator when it comes to creating value for our customers."
The ABB transformers are vibration and short-circuit resistant and have a compact footprint to accommodate the turbine door frame. They weigh approximately 30% less than standard and will be deployed inside the turbine tower with other low-voltage products.
ABB previously also won the contract to provide a high-voltage cable system to transmit power from the park.
