Get PriceGreenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (Sulfr hexafluoride) 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 radiatioSee more on epa.govMissing:FinlandMust include:FinlandFirst sf 6-free voltage transformers for 420 kV | References | siemens-energy/.../references/first-sf6-gas-free-voltage-transformers.htmlWorldwide, many TSOs intend to eliminate greenhouse gases for new installations of gas-insulated equipment and therefore continue to contribute to their voluntary self-commitment in SF 6 reduction. Until now, SF 6-free voltage transformers were available for voltages up to 245 kV.

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 gaz 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.
