Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

Sulfr hexafluoride decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into sf 6 so well that it is not necessary to replenish the Sulfr hexafluoride 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.

Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air. It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugi
