sf6 gas gas in medium-voltage switchgear - Siemens USA

In this issue, we discuss the use of sf6 gas (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.

Digital radiography for inspection of insulating gas | TD - Siemens USA

Based on the quantity and criticality of sf 6 breakers, Siemens determined that this would be the most applicable medium and circuit breaker to inspect utilizing DR. 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 sf 6 dead tank breaker, two to three exposures per phase are required to provide adequate data.
