Electrical cabinets are divided into electrical distribution cabinets and electrical control cabinets. PCL control cabinet refers to a programmable control cabinet that generally has protection functions such as overload, short circuit, and phase loss protection. Electrical control box or electrical control cabinet is a commonly used series of distribution control boxes in the low-voltage electrical industry. Electrical control cabinet refers to the assembly of switchgear, measuring instruments, protective electrical and auxiliary equipment in enclosed or semi enclosed metal cabinets according to electrical wiring requirements.


The electrical control cabinet should meet the normal operation of the power system, and at the same time, ensure easy placement for maintenance and not endanger the safety of personnel and other equipment. Normal operation requires the use of manual or automatic switches to connect and segment circuits. In case of malfunction, the circuit can be cut off.


The electrical control cabinet should choose a cabinet type suitable for installing PLC, usually using a fixed cabinet with a whole door panel. Cabinet types such as 90 fold cabinets, 16 fold cabinets, etc. should not be selected with GGD cabinets or cabinet door partitions, as they are not convenient for installation and debugging. Shenzhen Yifu has been specializing in the production of cabinets for more than 30 years, and takes every cabinet product seriously with the spirit of craftsmanship and professional attitude. Yifu's electrical control cabinets provide customers with a wide range of choices and can be purchased according to the different needs of the enterprise. At the same time, the product quality is superior, safe and reliable. The cabinet adopts a welded structure with a static load bearing capacity of over 1500KGS, and the cabinet is sturdy enough to meet the installation requirements of the equipment. Its seismic resistance has passed the domestic seismic tests of intensity 8 and intensity 9. Yifu's electrical control cabinet adopts a unique design framework and has applied for an exclusive patent. It is connected by double tube profiles and corner connectors, and can be welded or assembled in two structures. The overall structure is sturdy.

Secondly, the ventilation of the cabinet should adopt the form of air inlet from the bottom of the front door and air outlet from the top. The rear door should not be equipped with entry and exit risk control. It is best to install one ventilation filter at each air inlet and outlet to prevent dust. The external dimensions are mostly 320mm * 320mm. Due to the fact that the components inside the PLC cabinet generally emit less heat, natural convection is often used for heat dissipation and ventilation.


There are many specifications for the wiring ducts of the electrical cabinet, and the principle is to choose the specifications based on the sum of the volumes passing through this duct and about 80% of the capacity of my duct, because it is necessary to ensure a certain amount of heat dissipation space for the cables. The front door of the Yifu PT-S distribution control cabinet is a steel plate door with a thickness of 2.0mm, and the lower edge of the door is 25mm above the ground; The inner side of the door panel has reinforcing ribs with small circular holes spaced 25mm apart, which not only increases the strength of the door panel, but also can be used to install cable harnesses and electrical components; The opening method of the front door can be left or right according to needs; Profile glass doors can be selected. Moreover, Yifu also has numerous cabinets for enterprises to choose from according to their needs, and can customize non-standard products according to their needs.
