VGB series medium seal type vaccum circuit breaker is a kind of indoor three-phase medium-voltage AC switchgear with rated voltage of 12KV and rated frequency of 50Hz mainly used for breaking current, closing load current, overload current and short-circuit current in distribution network, which is applicable to the protection and control over the operation of substation, mines & other enterprises, and urban & rural power network, especially applicable to location with frequent operation requirement and automatization distribution of urban & rural power network.

It uses the latest insulation solid closure technology in the world. It is widely used by completely remove the incompatibility between miniaturization of vacuum interrupter and insulation requirement.

Moreover, it has many advantages such as small size, light weight, beautiful appearance, stable isolating property, long endurance,free of maintenance and sturdy construction.
