SF6 reducing system

SF6 reducing system

SF6 is used extensively worldwide for low switching capacity switches. In these applications, SF6 allows for extremely compact switching devices, sealed-for-life construction, and very low maintenance. Environmental issues In recent years, SF6 has been widely discussed in the environmental arena. SF6 is recognized as a very potent greenhouse gas.

  • SF6 Recycling: Guaranteed SF6 Recycling/Reconditioning

    SF6 (Sulphur hexafluoride) is a colorless, odorless, and non-flammable gas with very low reaction chemistry. It is used as an insulator for high-voltage circuit breakers, switchgear, and other electrical equipment. SF6 gas has high dielectric strength that allows for a significant reduction in the size of electrical equipment.

  • SF6 circuit breaker maintenance | TD Guardian Articles | USA

    In the 1970s, both domestic and foreign breaker manufacturers looked for ways to improve breaker interrupting technology based on the unique properties of SF6 while also reducing costs. This improvement was the implementation of puffer interrupters that snuff out the arc versus the earlier design of dual pressure breakers that utilized a two stage (pressure) system.

  • PGE Phases Out SF6 Greenhouse Gas | TD World

    Feb 21, 2019Like carbon dioxide, SF 6 is a greenhouse gas. While CO 2 has a global warming potential (GWP) of one, SF 6 has a GWP of 23,500. Although PGE reduced its SF 6 leak rate to nearly 1%, this came with an extreme operating cost. Eliminating the use of SF 6 would eliminate future leaks and result in reduced operating cost.
