With a length of 250 kilometres (160 mi), it was the second longest high voltage undersea cable on earth, until Basslink came into service in 2006.

After crossing the Priwall Peninsula the cable runs parallel to the coast of Mecklenburg-Vorpommern, before turning north-easterly toward Sweden.

[2] From the landing point at the southern coast of Sweden, the powerline transitions to an overhead line a few kilometres inland.

It is connected to Kruseberg converter station with a 23-kilometre-long underground and submarine power line, which consists of two parallel-connected cables with 630 mm2 cross section.

[citation needed] Because this overhead line can generate radio interference, there is a highly effective active filter system installed at the Kruseberg converter station.

The cable cannot be operated at the maximum transmission rating of 600 megawatts, because the 380 kV line which begins at the converter station of Lübeck-Herrenwyk ends at the Lübeck-Siems substation.

[citation needed] In 2016, the owner Statkraft started a court case against Swedish authorities in disagreements over profits from electricity trade in the cable.
