High current connectors to the world’s largest offshore wind farm

Sissach, Switzerland, February 2022 – R&S Rauscher & Stoecklin 400 connectors to Dogger Bank Wind Farm (currently under construction). Dogger Bank, located more than 130 km off the north-east coast of England, will be the world’s largest offshore wind farm when complete, capable of powering up to 6 million UK homes (5% of the UK’s demand). The Dogger Bank Offshore Development Zone extends over approximately 8660 km² and water depths range from 18 m to 63 m.

Some specifications of the project:

  • Type of device: 250 A high current connector
  • Quantity: overall 400 connectors
  • Technology: sea-water resistant solution (special housing resistant to salty environment)
  • Place of installation: Dogger Bank Wind Farm, UK

Electrical equipment and devices supplied to offshore wind farms must meet special conditions. The salt water environment requires the use of strong connectors able to handle the water (IP67) and the aggressive atmosphere. R&S Rauscher & Stoecklin had to deliver connectors in special sea water resistant design.
