1, The cabinet adopts the form of general cabinet and the frame is formed by partial welding and assembly of 8MF cold-bending section steel, the parts of the general cabinet are designed according to the principle of modules, and there are 20 die mounting holes, In the design of the cabinet, the heat dissipation problem in the cabinet operation is fully considered.The upper and lower ends of the cabinet body all have different Numbers of heat sink holes, when the electrical components in the cabinet heat, heat rise, through the upper end slot discharge, and the cold wind constantly from the lower end control supplement into the cabinet, so that the sealed cabinet body from bottom to top to form a natural ventilation duct, to achieve the purpose of heat dissipation.
2, This cabinet according to the modern industry product modelling design request, USES the environment to divide the method which the ratio designs the cabinet body contour and each part divides the size, causes the entire cabinet to be beautiful natural, the face is new
3, The instrument door with electrical components is connected with the frame with soft copper wire and the mounting parts in the cabinet and the frame with knurled screws. The whole cabinet constitutes a complete grounding protection circuit
4, After the surface treatment of the cabinet and the panel, the internal components such as epoxy powder electrostatic spraying coating, uniform adhesion, strong corrosion resistance mounting bracket, etc. are galvanized
5, The top cover of the cabinet can be removed when necessary for the convenience of assembly and adjustment of the main busbar on site. The four corners of the cabinet top are equipped with lifting rings for lifting and loading
