SF6 Breakers pipes for pinggao

SF6 Breakers pipes for pinggao

Much evidence has shown that air gas-blast circuit breakers have far inferior interruption capability than SF6 breakers. However, no clear explanation has so far been given regarding why an air switching arc has much larger time constant than an SF6 arc, and thus exhibiting far inferior interruption capability than the latter.
