Sulfur hexafluoride circuit breaker - Wikipedia

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 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, and relatively low maintenance. Developed in the 1950s and onward, sf6 gas circuit breakers are wid

insulating gas is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the sf 6 will not condense into a liquid at the lowest temperatures the equipment experiences. sf6 gas has two to three times the insulating ability of air at the same pressure. Sulfr hexafluoride is about 100 times better than air for interrupting arcs.
