GGD low-voltage fixed switchgear 380V 600A 1000A 2000A

Description

 

GGD 600A 1000A 2000A Indoor low-voltage fixed switchgear made in China 380V

Introduction of low-voltage fixed switchgear

 GGD AC low-voltage fixed switchgear is applicable to power plants, transformer substations and industrial mine enterprises. It is used in power distribution system at Ac 50hz, related working voltage of 380v and maximum working current of 3150a for power transformation, distribution and control of motor power, motor control and lighting.

GGD AC low voltage power distribution cabinet is a new type low voltage power distribution cabinet manufactured according to the requirements of authority of Ministry of Energy, customer and relevant designing departments in principle of being safe, economic, rational and reliable. Its features include high capacity of breaking, good stability of heating, flexible electric scheme, convenient combination, being systematic, good practicality and novel structure. It can be used to replace low voltage whole-set switchgear.

GGD AC low voltage power distribution cabinet accords with IEC439 low-voltage switchgear and control gear assemblies and GB725117 low voltage switchgear and control gear assemblies -part1:type tested and partially type tested assemblies.

Product structure features:

GGD AC low Voltage Power Distribution Cabinet body is in the form of universal cabinet framework is welded from local parts with 8MF(or amended by 8MF) cold forming sectional steel, structured parts and special parts are supplied by appointed steel manufacturers so as to guarantee the precision and quality. The parts of universal cabinet are designed in the module principle with 20mm installation holes. Its high coefficient of currency can realize pre-production in the factory, shorten production term and heighten work efficiency

B. The design of GGD Cabinet takes full account of the problem of heat extraction in the process of working. There are different amount of heat extraction holes on the top and bottom of the cabinet. When electric components heat, the quantity of heat will rise, but the heat will be ventilated from the top and the holes at the bottom will constantly supplement cool wind and form a natural ventilation path from bottom to top in the sealed cabinet and attain the aim of heat extraction.

C. According to the designing requirements of modern industrial products, the appearance design of GGD Cabinet and cutting size of various parts is in the method of golden section, which makes the whole cabinet beautiful and elegant

D. The door of cabinet is connected to the truss with rotated movable chain for convenient installation and dismantling. There is a Shan-shaped rubber bar at the folding side of the door and there is certain compression distance between the door and the truss when the door closes so as to prevent the door directly bumping with the cabinet and reinforced Protection class of the door

E. The instrument door installed with electric components is connected to the truss with many sections of soft copper wire the installation parts and the truss are connected with knurled thumb screws to form an entire grounding protection circuit

F. The coating paint is polyester orange-shaped paint or epoxy powder, which has strong adhesive strength, good tactile feel. The whole cabinet is in Matt color, which avoids dizzy effect and creates a comfortable visual environment for the on-duty personnel

G. The top of the cabinet can be dismantled if necessary for convenience of assembling and adjusting major bus bar on the spot. The four corners at the top of the cabinet are installed with flying rings for lifting and shipping

The Protection class of the cabinet is IP30 customers can choose between IP20 and IP40 according to the Operating environment.

Environment condition:

 1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
