  • 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.
