Sulfr hexafluoride Emissions | Sulfr hexafluoride Recovery | sf 6 Maintance | Electricity

Arcing occurs within circuit breakers whenever they operate. This process causes the absorption and deceleration of electrons, which in turn causes partial decomposition of the SF 6 gas. One of the main reasons why SF 6 is used as an insulating gas is its ability to recombine the decomposition products and regenerate itself.Get price
