  • What is SF6 Circuit Breaker? Construction, Working... - Circuit Globe

    SF6 gas is strongly electronegative, which means the free electrons are easily removed from discharge by the formation of negative ions. It has a unique property of fast recombination after the source energising spark is removed. It is 100 times more effective as compared to arc quenching medium.
