Structural characteristics
The cabinet body of GGD intelligent low-voltage switchgear distribution cabinet is in the form of universal cabinet. The frame is assembled by local welding of 8 MF cold-formed section steel. The frame parts and special supporting parts are supplied by the designated section steel manufacturer to ensure the accuracy and quality of the cabinet body.
The parts of the universal cabinet are designed according to the modular principle, and there are 20 mounting holes, so the universal coefficient is high. The factory can realize the pre-production. It not only shortens the production cycle, but also improves the work efficiency.
During the design of GGD intelligent low-voltage switchgear distribution cabinet, the problem of heat dissipation during the operation of the cabinet shall be fully considered. The upper end and the lower end of the cabinet body are provided with different numbers of heat dissipation slotted holes, when the electrical components in the cabinet are heated, the heat rises and is discharged through the slotted holes at the upper end, and the cooling air is continuously supplemented into the cabinet from the slotted holes at the lower end, so that the sealed cabinet body forms a natural ventilation channel from bottom to top to achieve the purpose of heat dissipation.
According to the requirements of modern industrial product design, GGD intelligent low-voltage switchgear distribution cabinet adopts the golden section ratio method to design the cabinet shape and the division size of each part, so that the whole cabinet is beautiful and elegant.
The cabinet door is connected with the frame by a rotating shaft type movable hinge, which is convenient for installation and disassembly. A mountain-shaped plastic strip is embedded outside the folding edge of the door, and the embedding strip between the door and the frame has a certain compression stroke when the door is closed, so that the direct collision between the door and the cabinet body can be prevented, and the protection grade of the door is improved.
Instrument doors equipped with electrical components shall be connected to the frame with multi-strand soft copper wires. The installation parts in the cabinet are connected with the frame by knurled screws, and the whole cabinet forms a complete grounding protection circuit.
Polyester baking varnish is selected as the top coat of the cabinet, which has strong adhesion and good texture. The whole cabinet is in matte tone, which avoids the dazzling effect and creates a more comfortable visual environment for the staff on duty.
The top cover of the cabinet body can be removed when necessary to facilitate the assembly and adjustment of the main bus on site. The four corners of the cabinet top are equipped with lifting rings for lifting and shipping.
The protection grade of the cabinet is IP30, and the user can also choose between IP20 and IP40 according to the requirements of the environment.
Normal service conditions:
Ambient air temperature is not higher than + 40 ºC and not lower than -5 ºC. The average temperature of 24H is not higher than + 35 ºC.
For indoor installation and use, the altitude of the place of use shall not exceed 2000 M.
Relative humidity of ambient air shall not exceed 50% at the maximum temperature of + 40 ºC. Greater relative humidity is allowed at lower temperatures. (E.g. 90% at + 20 ºC) The effect of occasional condensation due to changes in temperature shall be taken into account.
When the equipment is installed, the inclination to the vertical plane shall not exceed 5%.
The equipment shall be installed in a place without severe vibration and impact, and in a place where electrical components are not corroded.
If the user has special requirements, it can be solved through negotiation with our company.

What is switchgear?
Electrical switchgear refers to a centralized collection of circuit breakers, fuses and switches (circuit protection devices) that function to protect, control and isolate electrical equipment. The circuit protection devices are mounted in metal structures. A collection of one or more of these structures is called a switchgear line-up or assembly.
Switchgear is commonly found throughout electric utility transmission and distribution systems as well as in medium to large sized commercial or industrial facilities. Standards for electrical switchgear are defined by IEEE in North America and by IEC in Europe and other parts of the world.
What is low-voltage metal-enclosed switchgear?
Low-voltage metal-enclosed switchgear is a three-phase power distribution product designed to safely, efficiently and reliably supply electric power at voltages up to 1,000 volts and current up to 6,000 amps. Typical ANSI/NEMA (American National Standards Institute, National Electrical Manufacturers Association) switchgear is rated for up to 635 volts with a continuous current main bus rating of up to 10,000 amps (for supplying power from parallel sources).
Low-voltage switchgear is often found on the secondary (low-voltage) side of a power distribution transformer. This transformer and switchgear combination is known as a substation. Low-voltage switchgear is typically used to feed low-voltage motor control centers (LV-MCC), low-voltage switchboards and other branch and feeder circuits. It is used to supply electricity for critical power and critical process applications such as those found in heavy industry, manufacturing, mining and metals, petrochemical, pulp and paper, utility, water treatment as well as datacenter and healthcare.
