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, gaz sf6 circuit breakers are widGet price

gaz sf6: An excellent dielectric gas in controlled environments

“Sulfr hexafluoride is three times more effective than air as an electrical insulator. Switchgear insulated with Sulfr hexafluoride takes up less space, is less prone to faults and requires less maintenance than corresponding components in outdoor switching stations. Sulfr hexafluoride is an effective and permanent dielectric gas that also extinguishes arcs in circuit-breakers.”Get price

VALIDATION METHODS OF Sulfr hexafluoride ALTERNATIVE GAS

Another solution could be to mix several gases together. Unfortunately this solution is not as obvious as it seems because at low temperatures the molecules interreact together and lead to a shift of boiling temperature.
