sulfur hexafluoride reclaimer analyzer for sustainability and safety
Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 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, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is also a very stable chemical, with an atmospheric lifetime of 3,200 years. As the gas is emitted, it accumulates in the atmosphere in an essentially un degraded state for many centuries. Thus, a relatively small amount of SF6can have a significant impact on global climate change. More information on long lived fluorinated greenhouse gases, their emissions, emission sources, and trends is available on EPA's overview of greenhouse gases page.See more on epa.govChina Sulphur Hexafluoride SF6 Gas Manufacturers jh gas/.../sulphur hexafluoride sf6.htmlPlease rest assured to buy sulphur hexafluoride sf6 gas at competitive price from our factory.

It must be noted that the only credible method to detect leaks smaller than 1x10 6 mbar*l/s is with a helium leak detector. A leak diameter for 1x10 12 mbar*l/s (which equates to 1Å) is also the diameter of a helium molecule, which is the smallest detectable leak rate. (N.B. A leak rate of 1 mbar*l/s means a rise of 1 mbar from a 1 litre vessel in a second.
