hv sf6 n2 Gas-vacuuming 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 equipment that uses SF6.
