KEPCO Develops Sulfr hexafluoride Recycling Device to Combat Greenhouse Gas

Korea Electric Power Corp. (KEPCO) announced on July 9 that it has developed a sulfur hexafluoride (gaz sf6) refining device which recycles insulating gas emissions from discarded shutters and transformers. Sulfr hexafluoride is a greenhouse gas whose global warming effects are 23,900 times those of carbon dioxide. sf6 gas is used as an insulation material for high voltage power equipment due to its electrical insulation property.Get price
