  • 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.
