High-speed rail Gas-insulated

2018/7/19Europe: An International High Speed Network The next country to make high speed rail available to the public was France in 1981, with service at 200 km/h (124 mph) between Paris and Lyon. Today, the French high speed rail network comprises over 2,800 km of Lignes à grande vitesse (LGV), which allows speeds of up to 320 km/h or 200 mph, on which its TGVs (Trains à grande vitesse) run.

high voltage Sulfur Hexafluoride Load Development

high voltage Sulfur Hexafluoride Load DevelopmentGreenhouse 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.govDevelopment Status of High Voltage Insulation Technology researchgate.net/publication/342558392_Development...Sulfur hexafluoride is a gas ge nerated by the reaction of fluorine and sulfur.
