    Nov 01, 2018Preve et al. tested the C 4 F 7 N/dry air gas mixture and found that its insulation performance is better than that of SF 6 at the impulse voltage, but slightly inferior to that of SF 6 at the AC voltage (Preve et al., 2016). These studies confirm that the C 4 F 7 N gas mixture has excellent insulation properties. However, aging occurs in

  • Sulfur Hexafluoride (SF6) Emission Estimates for China: An

    Sulfur hexafluoride (SF6) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, SF6 emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest SF6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector

  • Separation and Concentration of SF6 from N2/SF6 Gas Mixtures

    For example, pure SF6 gas is used in gas insulated switchgears (GIS), gas insulated lines (GIL), and gas circuit breakers (GCB). One of practical solutions of controlling the emission rates of SF6 is to reuse by separation and recovery of SF6 of low concentration from the gases mixtures with nitrogen or air in the electric power industry.

  • Silicon etch using SF6/C4F8/Ar gas mixtures: Journal of

    May 30, 2014While plasmas using mixtures of SF 6, C 4 F 8, and Ar are widely used in deep silicon etching, very few studies have linked the discharge parameters to etching results. The authors form such linkages in this report. The authors measured the optical emission intensities of lines from Ar, F, S, SF x, CF 2, C 2, C 3, and CS as a function of the percentage C 4 F 8 in the gas flow, the total gas
