The vacuum contactor has the advantages of strong quenching ability, good pressure resistance performance, high operating frequency, long service life, no arc external spraying, small volume, light weight, long maintenance period and no noise.
The installation form of the 10KV high-voltage vacuum contactor in the switchgear can be either fixed or withdrawable, and can also be mounted on the frame.
