In 1953, the pioneering HVDC submarine cable system for the Gotland 1 link was laid between Västervik on the Swedish mainland and Ygne on Gotland. The turnkey project for Vattenfall included design, engineering, manufacturing, testing, and installation of a 96 km, 100 kV, 20 MW mass‑impregnated cable, completing the cable installation phase of the world’s first commercial HVDC submarine interconnection.
