SF6 gas in medium-voltage switchgear | T&D Guardian ... scale production began about 1953. By the 1960s, a number of designs of high-voltage SF6 circuit breakers were available. Predominantly, these were so-called "two-pressure" designs, in which a relatively low-pressure was used for insulation purposes, and a high-pressure system was used to interrupt the current.
