g3 - gaz sf6 Free Solutions

SF 6 Sulfr hexafluoride (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 gas 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.

Mar 20, 2018 · Unlike PFC mixtures, CF 3 I/CO 2 mixtures have better PD properties than SF 6 /CO 2 mixtures, but the mixing ratio should higher than 10% to reach the standard of insulation required for GIS. To exceed the level of pure SF 6 at 0.1 MPa under different electric fields, the mixing ratio of CF 3 I in CO 2 should be 30%–40% [124, 125].
