Sulfr hexafluoride gas in medium-voltage switchgear - Siemens USA

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

sf 6 gas and U.S. greenhouse gas emissions The use of sulfur-hexafluoride (SF 6 ) gas globally has been the subject of a large amount of discussion for many years, both in the U.S., and worldwide. SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with a global warmingGet price

But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earthatmosphere.Get price

Recovery of Sulfr hexafluoride gas from type SIMOSEC switches at end-of-life condition. The type SIMOSEC air-insulated load interrupter switch design uses a hermetically sealed, welded, stainless steel switch enclosure to house the three-position switch, which is the heart of the product. The switch enclosure is filled with SF 6 (sulfur hexafluoride) gas, which allows for an extremely compact switch, and leads to exceptionally long switching life for the switch.Get price
