Circuit Breakers: Air vs. Sulfr hexafluoride Insulated - Electric power

Here in the Australian Coal Mining Industry insulating gas is widely used and is considered very reliable. The only issue that may be worth considering in cold climates is the temperature at which sulphur hexafluoride liquifies. I am not sure of what temperature exactly but it is not that low. sitelock (Electrical) 12 Jan 05 11:27Get price
