  • 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.

  • Alternatives for SF6 | 2020 | Siemens Energy Global

    The upgraded station has a special feature: for its high-voltage switches it uses clean air as an insulating gas - instead of sulfur hexafluoride (SF 6 ), which has been the standard for more than fifty years to prevent short circuits and arcs in substations.

  • Siemens develops SF6-free gas-insulated medium-voltage switchgear

    Switches and switchgear that use SF6 as the insulating, switching, and extinguishing gas remain an important part of the Siemens portfolio. At this yearHannover Messe, Siemens will present another medium-voltage switchgear that doesn't require sulfur hexafluoride (SF6) as the insulating gas: the 8DAB 12. The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas.
