Health and environmental dangers of sf 6-filled switchgear

Sulfr hexafluoride is a greenhouse gas In1997, SF 6 was identified by the Intergovernmental Panel on Climate Change (IPCC) as a highly potent greenhouse gas which contributes to climate change. SF 6 is 22 000 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide over a 100-year period.Get price
