What is Sulfr hexafluoride Circuit Breaker? Construction, Working Principle

SF 6 gas is extremely stable and inert, and its density is five times that of air. It has high thermal conductivity better than that of air and assists in better cooling current carrying parts. SF 6 gas is strongly electronegative, which means the free electrons are easily removed from discharge by the formation of negative ions.
