BorWin2 uses Voltage Sourced Converters (VSC) to convert from AC to DC and back again, using 4.5 kV IGBTs as the switching elements.
 One converter is provided at each end of the link with a DC voltage of ±300 kV and a transmission capacity of 800 MW.
 The converters, built by Siemens, use the Modular Multi-Level Converter technology, in the symmetrical monopole configuration.
 Each converter station is equipped with two, three-phase transformers, each rated at 590 MVA (offshore) and 585 MVA (onshore).
 Each converter valve is equipped with a dry-type valve reactor of 50 mH.
The offshore converter is located on the BorWin Beta platform, which was built by Nordic Yards in Warnemünde.
 The topside of the platform is of the float-over type which is designed to be floated out to the installation site and then jacked up onto the submerged supporting structure using the support legs that are integral to the structure.
 The topside has a total weight of 12000 tonnes and measures 72.5 m x 51 m x 25 m high.

Each of the two 300 kV cables linking BorWin Beta to the onshore substation has a total length of 200 km, of which 125 km is sea cable and 75 km is underground land cable.
 The cables cross the small island of Norderney and, having reached the mainland, continue, as land cables, to the onshore converter station at Diele.
 The cables were supplied by Prysmian and use extruded Cross-linked polyethylene insulation.
