220kv sf6 vacuum deivces

Vacuum switch is a type of electrical switch where the flow of electricity is interrupted inside of sealed vacuum bottles. The vacuum allows the resulting arc to be extinguished quickly. Vacuum switches require less space than air or oil switches and can be applied at higher voltages. Vacuum switches are featured in Eaton's ISG-SD switchgear.
