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.Get price

Switchgear - Wikipedia

Switchgear for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.Get price
