sf6 gas properties - Power Systems Technology

Pure Sulfr hexafluoride is non toxic and biologically inert. Tests performed with animals have shown that when present in a concentration of up to 80% insulating gas to 20% O2, no adverse effects are experienced. Used insulating gas contains a multi-component mixture of chemical agents, one particular constituent has been shown to dominate in determining the toxicity.Get price
