sf6 insulated switchgear check for leaks for 220kv

This loss of conducting electrons in the arc quickly builds up enough insulation strength to extinguish the arc. Comparing to other circuit breaker types, the SF6 circuit breakers have been found to be very effective for high power and high voltage service. SF6 CBs are used in substations for all voltages ranging from 144 to 765
