Low-voltage fixed switchgear


Product series: Low-voltage fixed switchgear



● The cabinet of GGD type AC low-voltage distribution switchgear adopts the form of a general cabinet. The frame is welded by 8MF cold-formed steel. The frame parts and special supporting parts are produced and supplied by our company to ensure the accuracy and high-quality of the cabinet. The components of the universal cabinet are designed according to the principle of the module, and there are 20 module mounting holes, and the universal coefficient is high. Can enable the company to achieve pre-production. Not only shorten the production cycle, but also improve work efficiency.

● The design of the GGD cabinet fully considers the heat dissipation during the operation of the cabinet. There are different numbers of heat dissipation slots on the upper and lower ends of the cabinet. When the electrical components in the cabinet heat up, the heat rises and is discharged through the upper slot, and the cold wind is continuously added into the cabinet from the lower slot to make the sealed cabinet self A natural ventilation channel is formed from the bottom up to achieve the purpose of heat dissipation.

● The cabinet door is connected to the cabinet frame with a rotating hinge, easy to install and disassemble. A mountain-shaped sealing strip is embedded at the folding edge of the door. The sealing strip between the door and the frame has a certain compression stroke when the door is closed.

● The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper wire. The installation parts in the cabinet are connected with the frame by the knurled washer, and the whole cabinet forms a complete grounding protection system.

● The cabinet surface is treated with high-voltage electrostatic spraying process. With strong adhesion and good texture.

● The top cover of the cabinet can be removed when needed to facilitate the assembly and adjustment of the main busbar on site. The four corners of the cabinet top are equipped with lifting rings for lifting and shipping.

● The protection level of the cabinet is IP30, users can also choose between IP20 ~ IP40 according to the requirements of the use environment
