Structural characteristics and functions

1. The cabinet body of GGD AC low-voltage switchboard adopts the form of general cabinet. The frame is partially welded or assembled with 8MF cold-formed steel. The cabinet frame parts and special supporting parts are produced and supplied by our company to ensure the accuracy and quality of the cabinet body. The parts of the general cabinet are designed according to the module principle, and there are 20 mold mounting holes, and the general coefficient is high. Can bring the factory into production. Not only shorten the production period, but also improve the work efficiency.

2. GGD cabinet design fully takes into account the cooling problem in the operation of the cabinet. There are different number of heat dissipation slots at both ends of the cabinet. When the electrical components in the cabinet are hot, the heat rises and is discharged through the upper slot, and the cold air is constantly supplemented into the cabinet by the lower slot, so that the sealed cabinet forms a natural ventilation channel from the bottom up to achieve the purpose of heat dissipation.

3. GGD cabinet in accordance with the requirements of modern industrial product modeling design, using the golden ratio method to design the shape of the cabinet and part of the size of the partition, so that the whole cabinet beautiful and generous.

4. Cabinet door with rotary shaft type activity chain connected with the frame, installation, disassembly convenient. There is a mountain rubber and plastic strip embedded in the hem of the door. When closing the door, the strip between the frame has a certain compression stroke, which can prevent the direct collision between the door and the cabinet, and also improve the protection level of the door.

5. The instrument door with electrical components is connected to the frame with multiple strands of flexible copper wire. Knurled washers are used to connect the installation parts in the cabinet to the frame. The whole cabinet sample is a complete grounding protection system.

6. Cabinet surface paint can choose polyester orange baking paint, can also choose to spray plastic powder process. All have strong adhesion and good texture. The whole cabinet is matte tone, avoid glare effect, to create a more comfortable visual environment for the staff on duty.

7. The top cover of the cabinet can be removed when needed, so as to facilitate the assembly and adjustment of the main bus line on site. The four corners of the cabinet top are equipped with hanging rings for lifting and loading conditions

8. The protection level of the cabinet is IP30. Users can choose the protection level from IP20 to IP40 based on the requirements of the environment.

Conditions of use

1. The ambient air temperature shall not be higher than +40C and not lower than -5C; The average temperature within 24 hours is not higher than +35C;

2. For indoor installation and use, the altitude of the site shall not exceed 2000M;

3. The relative humidity of the surrounding air is not more than 50% when the highest temperature is +40, and it is allowed to have a larger relative humidity at a lower temperature; (e.g. 90% at +20C) The effect of occasional condensation due to temperature changes should be taken into account;

4. The inclination plane of the vertical plane shall not exceed 5 degrees when the equipment is installed;

5. The equipment shall be installed in the place without violent vibration and impact, and in the place where the electrical components are corroded.
