Properties of gaz sf6 (Sulfur Hexafuoride) GasHandling Nonfaulted Sulfr hexafluorideHandling Faulted sf 6Disposal of Wastea) Toxicitysf 6 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. Therefore, circuit breaker tanks shob) Toxicity Of Arc ProductsToxic decomposition products are formed when sf 6 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 not breathe the vapors remaining ic) Physical Propertiesinsulating gas is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. insulating gas shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically than air.

insulating gas Switchgear. Power Systems has the only CSA approval in Canada for sf6 gas switching technology (US as well) using the Arc-Whipper© three position switch. This design allows for an extremely small footprint and decreases maintenance cost and decreases the need for large electrical rooms which decreases costs and increases ROI.

High-performance vacuum pumps. Models GFU08-E and GFU08-C of the Sulfr hexafluoride gas cart series are fitted with vacuum pumps. With these, the air is extracted from the SF₆ gas compartments so that, afterwards, a professional filling can be made with SF₆ gas. The basic version of the vacuum pump (model GVP-10) already has a suction throughput of 10 m³
