XGN68-12(F)/630-31.5
This ring main unit is new generation miniature vacuum ring main unit, to replace of SF6 ring main unit. It is suitable for rated voltage 12kV, frequency 50Hz ring power supply and dual power supply system. As an electric control and protect device, it can be placed in box-type substation.
XGN68-12(F) indoor AC metal-enclosed ring main unit adopt modular design with vacuum interrupter and spring operating mechanism. It is compact in structure, small in size, simple in operation, reliable in interlock, long in mechanical life. This switch can open and close rated load current, close rated short-circuit making current, open transformer no-load current, open capacitive current between capacitor group and a certain distance of overhead lines. It can control, measure, protect the circuit and does reliable anti-misoperation interlock.
