66KV sf6 gas system Official website
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.govGas insulated switchgear | Portfolio | Siemens Energy Global siemens energy/.../gas insulated switchgear.htmlGas insulated switchgear. The Siemens Energy range of gas insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept. Since its introduction back in 1968, Siemens Energy has installed switch fields in all climatic zones of the earth, recording over 420,000 years of operation since.

245kV Sulfur Hexafluoride Leak Cost-effective
Feb 21, 2019Fixing a single SF 6 leak has an average cost of US$25,000. Ten percent of the installed dead tank circuit breakers (DTCBs) were leaking SF 6 in excess of the manufacturer certified leak rate and the probability of leakage was increasing with the aging of the DTCBs. Operating costs were forecasted to increase as a result of future increased SF 6 leaks.

High-speed rail sf6 gas Inspection Prospect
High-speed rail sf6 gas Inspection ProspectAug 24, 20173. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas tight compartments, greatly minimising leakage.
