Maintenance SF6 handling Vacuum

Aug 29, 2018The most important characteristics of the SF6 gas and vacuum-circuit breakers, i.e., of SF6 gas and vacuum as arc-extinguishing media are summarized in Table-1. In the case of the SF6 circuit-breaker, interrupters which have reached the limiting number of operations can be overhauled and restored to 'as new' condition.
