HALDEN, NorwayNexans has opened its newly expanded high-voltage subsea cable plant in Halden, Norway.

This will support various major projects including the company’s recently signed frame agreement with TenneT.

Construction of the expanded section, which started in November 2021, allows the company to apply the production technology to deliver subsea cables of up to 525 kV for high-voltage direct current (HVDC) and 420 kV for high-voltage alternating current (HVAC) applications.

The 34,000-sq-m expansion more than doubles the capacity of the plant for HVDC extruded cables, and the new 152.89 m tall second extrusion tower will allow the facility to insulate four cables simultaneously in addition to the two existing lines.

Although the focus will be on the production of HVDC cables for offshore wind farms, the facility can also serve other HVDC and HVAC applications.
