  • SF6 gas in medium-voltage switchgear - Siemens USA

    In this issue, we discuss the use of SF6 (sulfur hexafluoride) gas in medium-voltage switchgear. SF6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses SF6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

  • Wind farm places the first SF6-free Siemens high-voltage

    Apr 25, 2018 · Siemens supplied four bays of the 8VM1 gas-insulated SF6-free high-voltage switchgear (GIS) – which has a capacity of 72.5 kilovolts (kV) – to Siemens Gamesa Renewable Energy. The systems were deployed in the Nissum Bredning Vind wind farm in Denmark. The switchgear protect the wind turbines from overloads and short circuits and thereby ensure an uninterruptible power supply. The metal-encapsulated 8VM1 from the blue GIS portfolio was developed specifically for use in offshore wind turbines.
