  • Products - SF6-gas Gasbanor (Switzerland) GmbH, Micafluid

    SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2 ).

  • Air insulated switchgear | SF₆-free | Eaton

    The EU comission decided against a ban of SF 6 in switchgear, claiming that there were no widespread cost-effective, technically feasible, energy-efficient and reliable alternatives. Even with the ban for all other applications, scientific studies show that the concentration of SF₆ gas in the atmosphere continues to rise - a trend that is likely to accelerate due to the ever increasing demand for energy.

  • Electricity Transmission and Distribution Greenhouse Gas

    Sulfur hexafluoride is a commonly used insulator in electricity transmission and distribution equipment. Because of its high global warming potential (GWP), CARB adopted the Regulation for Reducing Sulfur Hexafluoride Emissions from Gas Insulated Switchgear in 2010. As new technologies using lower or zero GWP insulators emerge, CARB staff are proposing to amend the current regulation to further reduce greenhouse gas emissions and to increase flexibility in complying with the standards.
