SF6 Gas Construction value

This gas, which enjoys wide-ranging large and small scale uses, is readily condensable to a liquid, can then be stored, transported, metered, and dispensed under its own vapor The major problem with using SF6 in all of these applications is escape of the gas into the environment during handling.

  • What is SF6 Circuit Breaker? Construction, Working Principle

    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.
