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. If the normal oxygen content of air is reduced from 21 percent to less than 13 percent, suffocation can occur without warning. The…b) Toxicity Of Arc ProductsToxic decomposition products are formed when SF6 gas is subjected to an electric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs. Do n…c) Physical PropertiesSF6 is one of the heaviest known gases with a density about five times the density of air under similar conditions. SF6 shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically tha…See more on electrical-engineering-portalChina Ring Main Unit Switchgear/Switchboard/Gas and SF6 gas regard to extinguish arc and insulation dielectric, it is suitable not only in ring power supply and the double radiation power supply of 10kV medium pressure power supply network, but also can be used by terminal power supply.
