  • SF6 circuit breaker maintenance - Siemens USA

    SF6 gas leakage - SF6 breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be

    2015-4-15The 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.
