The cable tray in the computer room is a standardized cable laying management system specifically designed for data centers, server rooms, weak current rooms, and communication rooms. It is designed for high-density wiring and continuous operation of equipment in the computer room, and is the core supporting facility for modern intelligent computer room weak current, communication, and power line layout. The product can be made of various high-quality materials such as galvanized, aluminum alloy, electrostatic spraying, etc., combined with refined processing technology to create a regular and stable structure, suitable for the constant temperature and humidity operating environment of the computer room, and can resist the problem of line loss caused by slight indoor humidity and dust accumulation. In response to the characteristics of long-term operation of equipment in the computer room and concentrated heating of cables, the product has optimized the ventilation and heat dissipation structure, which can improve the efficiency of air circulation, timely dissipate the heat generated by cable work, avoid line aging caused by local heat accumulation, and ensure the continuous and stable operation of supporting lines for servers, switches and other equipment. At the same time, the product has good electromagnetic shielding performance, which can effectively weaken external electromagnetic signal interference, ensure the purity and stability of data transmission and signal communication in the computer room, and adapt to the operating standards of precision electronic equipment. There are no sharp burrs overall, and the wiring is neat and orderly, which can avoid hidden dangers such as cable wear and short circuits. It is fully compatible with standardized construction and upgrading projects of various data centers, communication centers, and intelligent centers at home and abroad.
