SF6 gas pressure for the insulating use is preserved below 2.5 bars while SF6 gas pressure for interrupting purpose is ranged from five to seven bar. Also, as vacuum technology isn't accessible for high voltage, so for C-GIS system above 72.5 KV, only SF6 is utilized both for insulation and interruption medium. Gas Insulated Switchgear Types
[email protected]SF 6 or other fluorinated gases, called F-Gases, are replaced by applying dry synthetic air, so called „clean air", as an insulation medium for gas-insulated equipment. Clean air consists of 80% nitrogen and 20% oxygen, natural elements in the surrounding atmosphere. With this new technology, there is no longer an obligation for F-gas reporting.

Get Pricewika sulfur hexafluoride Separating in SpainSulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, SF6 circuit breakers are wid
