  • Sulfr hexafluoride circuit breaker maintenance - Siemens USA

    The first generation of gaz sf6 circuit breakers was the lower voltage classes of 72kV and 145kV. As gaz sf6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.

  • Digital radiography for inspection of gaz sf6 | TD - Siemens USA

    Siemens typically performs several radiological exposures per phase to ensure that critical components are revealed. This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class gaz sf6 dead tank breaker, two to three exposures per phase are required to provide adequate data.

  • sf 6 gas in medium-voltage switchgear - Siemens USA

    In this issue, we discuss the use of Sulfr hexafluoride (sulfur hexafluoride) gas in medium-voltage switchgear. Sulfr hexafluoride has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses gaz sf6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
