  • 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.

  • SF6 alternatives, alternative Gases as SF6 substitute

    SF 6 is an excellent quenching and insulating gas which has been used in the energy sector worldwide for more than 50 years. The energy related development in the high and extra high voltage range would have been impossible without the use of SF 6 with its excellent dielectric stability and good electric arc quenching properties.
