Application

The switchgear serves for single bus and bus sectional system of rated voltage of 3-10kV and rated current of 630A-3150A three-phase AC 50Hz to receive and distribute electric power in power plant,substation and insustrial & mineral enterprise.

Main features

●The insolating moving door of primary contact featuring high security can automatically open or close when the trolley moves between the working position and in-and-out position,assuring the personal security during repair when it is electrfied.
●The enough electric insulation strength assures that the air gap between phases and between phase and ground inside the cubicle is above 125mm.
●The long-life vacuum arc chute and operating mechanism greatly reduce the repair work.

Application

The switchgear serves in the ring-network or radiation supply system of 12kV rated voltage,630A rated curent,especially in the pre-as-sembled substation to control and protect power system.

Main features

●The cabinet body is made of the aluminum-zinc-clad steel that can protect the operator once the inner fault occurs.
●The bus enclosed with insulation layer is connected to the terminals of load switch.The three-phase bus arrenges in longitudinal direction,which makes the free expansion of switchgear and the change of layout available.
