  • 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. The SF6 gas is costly, so it is reclaimed after each operation. This unit consists low and high-pressure chambers with a low-pressure alarm along with warning switches.
