Air insulated switchgear | SF₆-free | Eaton

The EU comission decided against a ban of SF 6 in switchgear, claiming that there were no widespread cost-effective, technically feasible, energy-efficient and reliable alternatives. Even with the ban for all other applications, scientific studies show that the concentration of SF₆ gas in the atmosphere continues to rise - a trend that is likely to accelerate due to the ever increasing demand for energy.Get price

Sulfur hexafluoride circuit breaker - Wikipedia

An SF 6 circuit breaker rated 115 kV, 1200 A installed at a hydroelectric generating station. Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.Get price

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
