Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

sf 6 Circuit Breaker Types, Working Principles Maintenance.

Feb 20, 2021 · gaz sf6 circuit breaker is an extinguisher that uses sulfur hexafluoride gas to cool and quench the arc. It is the type of circuit breaker used to protect electrical grids, power stations, and distribution systems. Sulfur hexafluoride gas has strong electronegativity and insulating properties, making them a better option than air and oil circuit breakers.Get price
