advantages of Gas Insulated Switchgear Disposal

Dec 19, 2019Gas insulated equipment is also more resistant to air contaminants and weather effects, increasing its longevity. While SF6 breaks down chemically when exposed to an arc, most of the altered material reforms or self-heals as SF6. As mentioned above, SF6 has come under fire as a potent greenhouse gas (GHG).
