siemens Sulfur Hexafluoride leakage and quality

Apr 15, 2015The California Air Resources Board (CARB) has mandated that leakage of sf 6 be reduced to one percent in 2020. The Siemens types 8DA and 8DB medium-voltage, gas-insulated switchgear designs, with a leakage rate of less than 0.1 percent per year, are already below the 2020 limits mandated by CARB.
