sf6 gas DETERMINATION Schneider

Sulfur hexafluoride (SF6) is one of the most stable gaseous chemical compounds due to its inertness (Its inertia is comparable with nitrogen (N2) gas) and incombustible nature. It has been more than 6 decades since SF6 is being used in electrical equipment. In fact, Switchgear amounts to 90% of the electronic

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic.
