SF6 provides superior insulation
SF6 gas is a popularly used insulating medium in high-voltage switching and protection equipment. It is non-flammable, non-toxic, and inert. SF6 has 2.5 times the dielectric strength of air and is 100 times more effective at quenching arcs. It also dissipates heat much better than air. No other gas offers better combined insulating and interrupting properties. Compared to insulating media such as air and oil, SF6 provides safer operating practices for utility personnel. With SF6-filled equipment, circuit interruption is performed within a sealed container, limiting the consequences of an arc flash if an internal fault were to occur. All current-carrying components are protected from moisture, corrosion, vegetation, and animal intrusion.
