Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (sf 6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on Sulfr hexafluoride in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, insulating gas is 22,800 times more effective at trapping infrared rSee more on epa.govMissing:TurkeyMust include:TurkeyWholesale Sf6 Circuit Breaker - Sf6 Circuit Breaker Manufacturers, ec21/ec-market/sf6-circuit-breaker.htmlCompetitive sf6 circuit breaker products from various sf6 circuit breaker manufacturers and sf6 circuit breaker suppliers are listed above, please select quality and cheap items for you.

Properties of sf 6 (Sulfur Hexafuoride) GasHandling Nonfaulted sf 6Handling Faulted insulating gasDisposal of Wastea) ToxicitySulfr hexafluoride 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 PropertiesSulfr hexafluoride is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. Sulfr hexafluoride 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.
