Cubicle Fixed AC Metal-clad RMU Switchgear HXGN1-12

Cubicle Fixed AC Metal-clad RMU Switchgear HXGN1-12

HXGN1-12 Cubicle Fixed AC Metal-clad RMU Switchgear (hereafter refer to as "Ring Main Unit") is a new generation of high voltage electric products which are applied to the projects for upgrading urban power grids, by introduction of advanced technology from home and abroad.. By type test and long-term commissioning test, this product is up to IEC 298 standard [Alternative Current Metal-clad Switchgear and control-gear from 1kV to 52kV, including 52kV] and At the same time, we have made reliable false-protected measure which makes the protection level by IP2X . It is small in size£¬light in weight, easily operated, less in space, safe in use, easily maintained, stable quality, free of fire disaster or explosion disaster and can be installed against the wall. Comparing and analyzing relevant foreign documents, and through some experts evaluation, main technical data of this product comes up to the same level as that of similar products abroad.
      RMU is suitable for distribution system with three phases, 10kV rated voltage, 50HZ rated frequency in places such as factory or mining enterprise, residential district, high rise building, school, park, etc. It could also be used in ring net or terminal power supply.

Product feature :
       a.The enclosure of ring main unit has two structures: One is composed of basic frame, roof plate, faceplates and side plates. And the basic frame is made of bent and weld cold rolled sheets. The roof plate, faceplates and side plates are made of steel sheets.
Another structure is made up of left side plate, bottom plate, ceiling plate and columns. The frame is made of imported bent zinc plate coated with aluminum.

      b. There are busbar compartment on the ceiling of the ring main unit, in front of which is instrument compartment isolated by steel plate or epoxy resin plate, load switch compartment on its top, cable outgoing line on the down-central and others electric element compartments.
      c. The main components include load switch, earthing switch, fuse, current transformer, and voltage transformer lightning arrestor, capacitor and HV electricity indicator etc.
      d. Voltmeter, current meter, light switch, indicator and operation elements can be fitted in the instrument compartment. The group terminal block and backup circuit  breaker of secondary circuit can be fitted on the terminal board at the bottom of the instrument compartment. Watt meter, var meter,  peak to valley meter, and batch meter can be added to the instrument compartment of the Measurement cubicle.
