Sulfur hexafluoride - Wikipedia

Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".Get price

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

The actual Sulfr hexafluoride 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.
