Jun 05, 2020Sf6 is 100 times more effective than air in quenching accidental arcing. Has high thermal conductivity; It is an inert and stable gas, and its density is higher than air. Sf6 is an electronegative gas, which makes it an excellent insulator. It is a better extinguisher than an air medium. SF6 is non-flammable, meaning there is no risk of a fire outbreak.
