1/12/2020Schneider Electric's new "air and vacuum" SF 6-free switchgear serves as a good example. sf 6 is a greenhouse gas 23,500 times stronger than CO2. Sulfr hexafluoride acts as a powerful electrical insulator and is found within most of the existing

Siemens will equip a 145-kilovolt (kV) substation owned by E.ON Sweden with sf6 gas-free high-voltage products by the middle of 2020. The orders comprise six bays, including circuit breakers for 72.5-kV and 145-kV as well as 145-kV instrument transformer

7/9/2013sf 6 GIS. The sf6 gas gas insulated metal enclosed switchgear shall be totally safe against inadvertent touch of any of its live constituent parts. It should be designed for indoor application with meteorological conditions at site (winter 3&C to 14& C and summer 31& C to 46& C, seismic zone: IV) . General Technical Specification For 220kV Sulfr hexafluoride

13/9/2019Climate change: Electrical industry's 'dirty secret' boosts warming. It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned

For most of these applications, there is no way that the cost of a 115 kV or 230 kV circuit breaker could be justified. The circuit switcher has the following benefits over circuit breaker : Compact, low cost, and some models include a visible break switch in their operation.

Environmental ConcernsSafety ConcernsSpecial Handling ProceduresInstallation ConcernsOperation and Maintenance ConcernsEnd of Life and Recycling ConcernsThe insulating gas used in MV GIS switchgear,sulfur hexafluoride (sf6 gas), is a highly potent greenhouse gas with a global warming potential 23,900 times greater than CO2. insulating gas also has an atmospheric life of 3,200 years, so it will contribute to global warming for a very long time.
