Sulfur hexafluoride - Wikipedia

Like xenon, sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled. Since it is more dense than air, a substantial quantity of gas, when released, will settle in low-lying areas and present a significant risk of asphyxiation if the area is entered.Get price

Sulfur hexafluoride circuit breaker - Wikipedia

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. This loss of conducting electrons in the arc quickly builds up enough insulation strength to extinguish the arc.Get price

Myth About sf6 gas Gas In Electrical Equipment

Apr 12, 2021 · Basically there is no difference as both applications use the sf 6 in gas-tight compartments with negligible leakage rates.
