Relevance of Sulfr hexafluoride in Switchgear and its Contribution to

Sulfur hexafluoride (Sulfr hexafluoride) 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 Sulfr hexafluoride is being used in electrical equipment. In fact, Switchgear amounts to 90% of the electronic equipment that uses Sulfr hexafluoride.
