Encyclopedia > Berlin 380 kV electric line

The Berlin 380-kV electric line is a 38.3-km double-circuit high-voltage electric three-phase power line in Berlin. An unusual system for a municipality, it was installed by the West Berlin Bewag utility company during the division of the city. Since 1951, West Berlin had been cut off from the East Berlin and East German power networks, and maintained an independent power generation capacity that was not connected to any other power grid. Berlin was connected to the western European power grid in 1994, following German reunification, by extending the 380-kV line. Josephson junction array chip developed by NIST as a standard volt. ...

The first section of the line, which entered service in 1977, was an interconnector that consisted of a 2.6 km overhead transmission line and an 8.1 km underground cable, which ran from Reuter power station in Spandau to Mitte substation in Tiergarten ("Mitte" means "central"; the district of Berlin-Mitte was then in East Berlin). This was the first line to use plastic insulators. The overhead segment and an adjacent 110-kV line are the only overhead lines in former West Berlin. The underground section used water-cooled cable in an accessible tunnel. Both substations use totally enclosed SF6-insulated switchgear. They are the oldest 380 kV substations with SF6 technology in Germany. For the album by Ash, see 1977 (album). ...

After German reunification the Berlin 380-kV interconnector was extended 7.6 km further west to Teufelsbruch substation in Spandau Forest, near Berlin's western border in 1994. From here the city was finally relinked to the western German power grid via a new 170-km transmission line, linking Teufelsbruch to Helmstedt, just behind the former inner-German border. The new line ran through Wolmirstedt substation near Magdeburg.
