Gas density of gaz sf6 and other gases - Trafag AG

Sulphur hexafluoride (Sulfr hexafluoride) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe ­power distribution systems even in large cities. The insulation strength depends basically on the gas density.Get price

Myth About sf 6 Gas In Electrical Equipment

Aug 24, 2017 · I understand that power transformers with insulating gas dielectric are used extensively in Japan, but not much elsewhere, because of the much higher purchase price compared to conventional oil dielectric transformers. Presumably this is mainly because of the reduced fire risk with sf6 gas transformers.Get price
