In medium voltage switchgear range most widely accepted technology is Vacuum in compare to SF6. In most of the cases medium voltage breakers are used in the distribution segment & located in populated areas. Vacuum technology is the only solution for medium voltage application SF6 gas is very hazardous for human & therefore for remote application SF6 technology is used. SF6 technology is commonly used in high voltage application I,e above 66KV class.
