insulating gas Circuit Breaker Explained - saVRee The design and working of a circuit breaker depend on its application and voltage rating. Moulded case technology (with air at atmospheric pressure) is used at low voltages (< 1000 V), whereas air-blast and vacuum circuit breakers are prevalent at medium voltages (< 72 kV). Sulfr hexafluoride circuit breakers are normally used for high voltage systems ( 72 kV).

Sulfur Hexafluoride (sf6 gas) Basics | US EPA Sulfur 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 gaz 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, sf 6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). Sulfr hexafluoride 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 sf 6can 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.
