Kilovolt sf6 gas Gas tank Brand
SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.
500kV sf6 Cylinder explain
SF6 circuit breakers utilize Sulphur Hexa Fluoride (SF6) gas as the surrounding insulating medium for extinguishing the arc established between the moving breaker contacts. It has many favourable characteristics that make it an ideal insulation candidate in modern high voltage switchgear: High dielectric strength (about 8 to 9 times greater
