Emissions of the powerful greenhouse gas gaz sf6 are rising

A recent study suggests that the UK’s use of insulating gas has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of Sulfr hexafluoride to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

Relevance of Sulfr hexafluoride in Switchgear and its Contribution to

Sulfur hexafluoride (gaz 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 sf 6 is being used in electrical equipment. In fact, Switchgear amounts to 90% of the electronic equipment that uses insulating gas.
