GGD low voltage switchgear

GGD low voltage fixed switchgear assembly can be widely used in power plants, substations, mines factories and other electricity users in AC 50HZ, rated voltage 400V, rated current 3150A distribution system. As use of power conversion, distribution and control on power equipment, lighting and power distribution equipment.
GGD type with low voltage distribution cabinet has a high breaking capacity, dynamic and thermal stability, novel structure, reasonable, realistic electrical program, series, applicability and higher protection class characteristics that can be used as replacement products.
This product complies with of IEC60439 <<Low-voltage switchgear and control equipment>>, standard GB7251 •1 <<Low-voltage switchgear and control equipment: the type test and partial type test equipment>> etc.

II. Features
1?GGD AC low voltage power distribution switchgear equipment cabinet takes the general purpose type. Its frame made by 8MF cold-formed steel and partially welded together, frame parts and special supporting parts manufactured by the company that supporting supplier to ensure the accuracy of the cabinet and quality. The parts of the universal cabinet follow module schematic design and have 20 modulus mounting holes, well universal coefficient. Allow the company to achieve the pre-production. Not only shorten the manufacturing cycle and also improve the work efficiency.
2?The design of GGD cabinet fully considers the heat dissipation problem in the cabinet run. There have different quantity cooling slots in the cabinet both ends from top to bottom. When the electrical components heating and the temperature rise, the heat will be discharged through the top slot while the cold wind constantly added into the cabinet from the bottom slot, so that makes sealed cabinet formed on a natural air duct from bottom to top that meets cooling purpose.
3?GGD cabinet in accordance with the requirements of modern industrial product design using the golden ratio designed cabinet shape and the various parts of the partition size, so that the whole cabinet is nice
4?The door use shaft-type hinge connect the frame that activities to the installation and easy removal. At the hem of the door has embedded a mountain-type seal which between the door and the frame when the door closed, produce a compression stroke that to prevent the direct collision of the door and the cabinet and also increased the level of protection the door.
5?The instrument door of the electrical components is equipped with multi-strand soft copper wire which connect with the framework. With knurled washer connection between the cabinet mounting framework make the entire cabinet to form a complete ground protection system.
6?The cabinet surface takes the high pressure electrostatic spray treatment process. With strong adhesion and good texture the entire cabinet is matt colors that avoid the glare effect to the duty officer and create a more comfortable visual environment.
7? If needs, the cabinet top cover can be removed in order to facilitate site assembly and adjustment of the main bus. And the roof of the four corners is equipped with rings for lifting and shipment.
8?The cabinet protection level is IP30, users can based on the use of environmental requirements to choose class between IP20 ~ IP40 .

III?Normal use of the environment and conditions
1.An ambient air temperature is not higher than +40? and lower than -5?; the average temperature is not higher than +35? within 24h
2.Weather conditions, clean air, relative humidity does not exceed 50% in the maximum temperature +40 ? over but at lower temperatures allow higher relative humidity.
3.This product is applicable to the transportation and storage of the following temperature: the range between -25? to +55? will be up to +70? in a short time (less than 24H) , the device should not get any irreversible damage in these extreme temperatures; and under normal conditions should be able to work properly.
4.If the above conditions can not meet, users should rise to factory side during the order stage to discuss the settlement.
