The network cabinet should have good technical performance. The structure of the cabinet should be designed physically and chemically according to the electrical and mechanical properties of the equipment and the requirements of the operating environment, to ensure that the structure of the cabinet has good stiffness and strength, as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation performance. In addition, the network cabinet should have performance such as vibration resistance, impact resistance, corrosion resistance, dust prevention, waterproofing, and radiation protection to ensure stable and reliable operation of the equipment. The network cabinet should have good usability and safety protection facilities, which are easy to operate, install, and maintain, and can ensure the safety of operators. The network cabinet should be easy to produce, assemble, debug, and package for transportation. The network cabinet should meet the requirements of standardization, standardization, and serialization. The cabinet design is beautiful, applicable, and color coordinated.
