Why are SF6 gas handling requirements increasing?

SF6 gas handling requirements have increased over the years because of environmental and governmental concerns. “How do you prepare in advance for possible changing regulations?” We need to plan for the future – NOW!

Can SF6 be used in switchgear?

A brief history of the use of SF6 in switchgear is given. The effects of SF6 on the environment are discussed. Guidance is given for working with SF6 gas and SF6 filled equipment under normal and abnormal conditions of service.

What happened to SF6?

Goodbye SF6! Clean Air technology from Berlin Take a glimpse inside the Switchgear Plant Berlin, an icon of industrial history, where Siemens Energy is creating a revolution with high-voltage switchgear and systems entirely free of SF6 and other potent greenhouse gases.

What is SF6 used for?

More recently, SF6 has been adopted for use in MV switches, ring main units, contactors and circuit-breakers, GIS, covering all the needs of the elecrical distribution industry. fig. 1 : process of SF6 production by direct combination. The purification chain is necessary to obtain high purity gas.

What drives SF6 emissions in medium voltage switchgear?

This relates to a banked volume of 8600 t SF6 or an equivalent of 196 million tons of C02. Three main drivers define the development of SF6 emissions in medium voltage switchgear: network extensions, operation emissions, and end-of-life handling. The end-of-life handling has the key role. Network extension effects are also significant.

Will SF6 emissions rise exponentially?

SF6 emissions will rise exponentially alongside expanding electrified energy infrastructure using equipment containing this gas. This, together with repeated SF6 leaks, perpetuates the worryingly steep upward trend in atmospheric content of SF6 shown above.
