Siemens Energy entrusts PFISTERER with turnkey cable systems for offshore projects DolWin4 and BorWin4

Winterbach, Germany – PFISTERER, the international quality leader in electrical connection technology for energy infrastructure, is supplying turnkey cable systems for the BorWin4 and DolWin4 offshore grid connections, thus continuing its long-standing cooperation with Siemens Energy. The two platforms enable the highly efficient transmission of offshore wind energy to the German mainland, making a significant contribution to a renewable energy supply.

EXTENSIVE KNOW-HOW IN CABLE SYSTEMS

PFISTERER is in charge of implementing the entire 66 kV AC cable infrastructure between the gas insulated switchgear (GIS), transformer and submarine cable connection on the DolWin4 and BorWin4 platforms. This involves planning, comprehensive engineering services, as well as installation and project management. Alternating current from offshore wind turbines is converted into direct current on the platforms in order for the electrical energy to be transported with maximum efficiency and minimal losses over long distances to land. BorWin4 and DolWin4 are scheduled to go into operation in 2028 around 125 kilometers northwest of the island of Borkum in the North Sea. With a transmission capacity of 900 megawatts each, they can transport enough electricity to cover the energy requirements of a large city such as Hamburg with 1.8 million inhabitants.
