Properties of SF6 (Sulfur Hexafuoride) GasHandling Nonfaulted SF6Handling Faulted SF6Disposal of Wastea) ToxicitySF6 is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. Ib) Toxicity Of Arc ProductsToxic decomposition products are formed when SF6 gas is subjected to an elec­tric arc. The decomposition products are mec) Physical PropertiesSF6 is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. SF6 showd) Dielectric StrengthSF6 has a di­electric strength about three times that of air at one atmosphere pressure for a given electrode spacing.

(Types and Operation electrical4u/types-and-operation-of-sf6-circuit...20/03/2013Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical
