Sulfr hexafluoride (GIS) gas insulated substation Manufacturer in China

The initial ionization potential of the Sulfr hexafluoride 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 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.Get price
