advantages of sf6 Load break switch recharge kit

The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using SF6 as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV.
