installed and used in-house.


The ambient air temperature is not higher than 40 degrees C, not less than -5 degrees C, and the average temperature within 24h is not higher than .35 degrees C.


The air is clean and the relative humidity does not exceed 50 at a maximum temperature of 40 degrees C. Higher relative humidity is allowed at lower temperatures. For example, the relative humidity is 90 at 20 degrees C, but it should be taken into account that due to temperature changes, it is possible to occasionally produce moderate condensation.


The altitude is not more than 2000m.


The pollution rating is 3.


The tilt of the installation and vertical face of the unit shall not exceed 5 degrees.


The transport and storage temperature is -25 degrees C to 55 degrees C, and in a short period of time (no more than 24h) can reach 70 degrees C.


Users may negotiate with the manufacturer if they have special requirements.


  • Overview
  • Features
  • Use environment

GGD low voltage set switching equipment (hereinafter referred to as device) is suitable for power plant, substation, plant and mining enterprises and other power users of the EXCHANGE 50Hz, rated operating voltage 400V, rated operating current to 3200A distribution system, as power conversion, distribution and control of power, lighting and distribution equipment.


The device conforms to GB7251.1 standard and is certified as 'CCC'.

The device has the characteristics of high breaking ability, flexible electrical scheme, convenient combination, series, practicality, novel structure and high protection level.


1, GGD-type AC low-voltage distribution cabinet body using the form of a universal cabinet, the structure with 8MF cold-bending steel bureau welding assembly, frame parts and special supporting parts by the type of steel fixed-point production plant supporting supply, to ensure the accuracy and quality of the cabinet body. The components of the general cabinet are designed according to the principle of the module, and the general coefficient is high by the 20-mode mounting hole. Pre-production can be achieved in the plant. It shortens the production cycle and increases the efficiency.


2, GGD cabinet design fully take into account the cooling problems when the cabinet is running. There are different numbers of cooling slots at both ends of the cabinet


Holes, when the electrical components in the cabinet heat, heat rise, through the upper slot hole discharge, and the cold air is constantly replenished by the lower end slot hole into the cabinet, so that the sealed cabinet body from the bottom up from the formation of a natural ventilation channel, to achieve the purpose of cooling ground.


3, according to the modern industrial product design requirements, the use of gold division method design cabinet shape and the split dimensions of various parts, so that the overall beauty and generous, new face.


4, the door with the rotary shaft-type active hinges and the frame connected, installation. Easy to remove. There is a mountain-shaped rubber strip at the edge of the door, and the inlay between the door and the frame has a certain compressed stroke when closing, which can prevent the door from colliding directly with the cabinet, and also improve the protection level of the door.


5, equipped with electrical components of the instrument door Oh that multi-stranded soft copper wire and the structure connected. The mounting slot in the cabinet is connected to the frame by rolling screws, and the entire cabinet forms a complete ground protection circuit.


6, cabinet decent paint selection polyester orange-shaped paint. Strong adhesion, good texture. The whole cabinet is matte, avoiding the dazzling effect, creating a more comfortable visual environment for the duty personnel.


7, the top cover of the cabinet can be removed when needed, easy to the site main bus assembly and adjustment, the top of the cabinet is equipped with a hanging ring, for lifting and shipping.


8, cabinet body protection level IP30, users can also be based on the requirements of the use of the environment between IP20IP40.
