Hansa PowerBridge is proceeding via a Request for Information (RFI) for the Converter Stations and Cables
Svenska kraftnät and 50Hertz have started with the collection of information for the supply and installation of Hansa PowerBridge.
Planned Contract (to be procured by Svenska kraftnät) for:
- Two converter stations (VSC)
- One cable section station in Germany
Planned Contract (to be procured by 50Hertz) for:
- Onshore Cables (60km+70km DC, 2km AC)
- Offshore Cables (88 km+88 km DC)
The main technical data are the active power of 700 MW transmitted via a symmetrical monopole (at receiving end) with a DC voltage of +/-300kV and AC voltage of 400kV level.
All cables will consist of an extruded cable insulation. The two submarine HVDC cables and a submarine FOC are bundled prior to laying. After laying the bundle shall be protected by burial or a rock berm. Maximum water depth for submarine cable approximately 50 meter. The underground cables in Germany are installed in preinstalled ducts (ducts not in scope, contracted separately). The underground cables in Sweden are installed directly buried.
