    2018-11-1Research on SF 6 mixture. Since the 1970s, the research on SF 6 gas mixture as an insulating material has gradually expanded. The primary purpose of the research is to solve the issue in extremely cold areas, where SF 6 could easily liquefy. SF 6 is expensive and sensitive to nonuniform electric field and other issues.Cited by: 14
