    8. SF6 gas leakage - SF6 breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.

    Characteristics of SF6 Gas. SF6 Gas is a colorless, odorless, non-flammable, and harmless to humans and animals in low quantities. It is an incredible electrical insulator, which is why it is used as an arc quenching medium for higher voltage switch-gear. So what are the negatives? Unfortunately, SF6 has been deemed as the most potent greenhouse gas that has ever been evaluated.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    SF 6 gas is electronegative and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of sulfur hexafluoride gas, and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.
