gaz sf6 gas as insulating and arc-quenching medium

Sep 20, 2011 · Sulphur hexafluoride gas (Sulfr hexafluoride) is employed as insulation in all parts of the installation, and in the circuit-breaker also for arc-quenching. sf 6 is an electronegative gas, its dielectric strength at atmospheric pressure is approximately three times that of air. It is incombustible, non-toxic, odourless, chemically inert with arc-quenching properties 3 to 4 times better than air at the same pressure.

Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

gaz sf6 decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into sf6 gas so well that it is not necessary to replenish the sf6 gas in GIS. There are some reactive decomposition byproducts formed because of the interaction of sulfur and fluorine ions with trace amounts of moisture, air, and other contaminants.
