Sulfr hexafluoride gas in medium-voltage switchgear | TD - Siemens USA

In this issue, we discuss the use of sf6 gas (sulfur hexafluoride) gas in medium-voltage switchgear. sf 6 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 Sulfr hexafluoride gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.Get price

Digital radiography for inspection of Sulfr hexafluoride | 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.Get price
