What is insulating gas Gas? | GasQuip - Sulfr hexafluoride Equipment and Training

The actual insulating gas gas itself is ripped apart by the immense amount of energy passing through it, but much like wolverine (or Deadpool, Spiderman etc.), the gas heals itself and recombines at the atomic level. Unfortunately, other byproducts can also be formed like water and sulfur dioxide, which causes problems for the longevity of electrical components. Hence the need for good testing equipment.
