SF6 gas Mixtures process equipments

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.

    SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Thus, it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas due to its properties. Unfortunately, the same properties that make SF 6 an excellent insulating gas for GIE also make it a potent greenhouse gas.

    The key difference between g3 and SF6 is that g3 is a gas mixture while SF6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.
