SF6 (GIS) gas insulated substation Manufacturer in China ... initial ionization potential of the SF6 gas is the same to nitrogen. The size of the sf6 molecule is much higher than a nitrogen. That practicality denotes that the free path for an electron impact in SF6 gas is at least a third of the path which it is in nitrogen. What's more: Kinetic energy is considered a function of the velocity squared.
Alternatives for SF6 | 2020 | Siemens Energy Global 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 earth's atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to ...
