low cost sulphur hexafluoride Vacuum

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 (sf6-gas) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases,
