Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

It is the universally used interrupting medium for high-voltage circuit breakers, replacing the older mediums of oil and air. Repeated recycle of Sulfr hexafluoride gas gaz sf6 decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into Sulfr hexafluoride so well that it is not necessary to replenish the sf 6 in GIS.Get price
