Advantages of SF6 decomposition Transfer

Advantages of SF6 decomposition Transfer

SF6 not only possesses a high dielectric strength, but also, its molecu1es. when dissociated due to spark overs, recombine rapidly after the source. energizing the spark is removed and the gas recovers its strength. SF6 is approximately 100 times as effective as air in quenching arcs.
