Qinghao Electric is developing and producing a variety series LV MV and HV switchgears including below: KYN, XGN, HXGN, XGW, DFW, GGD, GCK, GBD, PGL MNS and so on.
GGD Low Voltage Fixed Switchgear is one kind of AC low-voltage fixed power distribution cabinet. It is suitable for three-phase AC 50Hz, rated working voltage 400V, rated working current 4000A indoor complete set of power distribution device.
Main Characteristics
Qinghao switchgear meets the requirements of GB7251, JB/T9661, IEC60439 related standards.
1. High breaking capacity.
2. Good dynamic and thermal stability.
3. Flexible electrical scheme.
4. Convenient combination, strong practicality.
5. Novel structure and high protection level.
Advantages
1. Cabinet frame is assembled by local welding of 8MF cold-formed steel, and has 20 molds of mounting holes, and the general coefficient is high.
2. Fully consider the heat dissipation problem in the operation of the cabinet, and there are different numbers of heat dissipation grooves at the upper and lower ends of the cabinet, so that the sealed cabinet forms a natural ventilation channel from bottom to top to achieve the purpose of heat dissipation.
3. The instrument door equipped with electrical components is connected to the frame with multi-stranded copper flexible wires, and the installation parts in the cabinet are connected with knurled screws between the frame, and the whole cabinet constitutes a complete grounding protection circuit.
4. The surface of the cabinet adopts electrostatic spraying process, which has strong adhesion and good texture, and the whole cabinet is matte color, avoiding the dazzling effect.
5. The door panels and sealing plates around the switchgear are made of 2mm cold-rolled steel plate, and the protection level of the cabinet body is IP3X.
Applications
Mainly used in power plants, substations, industrial and mining enterprises, institutions and other power systems as power, lighting and distribution equipment for power conversion, distribution and control.
Service Environment
1. Ambient temperature: -30°C to +45°C
2. Altitude: ≤1000 meters.
3. Max. air relative humidity90%(±25ºC);
4. Max. Ground ramp degree 3°;
5. The earthquake: the horizontal acceleration≤0.3m/s2 , the vertical acceleration≤0.15m/s2
6. The installation site shall be free from explosion danger, fire, filthy material, chemical corrosion and violent vibration;
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
