Porous cable tray is a core supporting product for modern weak current, precision electrical, and high-density wiring engineering. With a structure design with uniform openings on the board, it breaks through the heat dissipation limitations of traditional enclosed cable trays and has good ventilation and air permeability conditions, making it very suitable for cable laying scenarios that operate continuously for a long time. The product is made of high-quality steel plate as the base material, processed through multiple processes such as precision stamping, integrated bending, and leveling and shaping. The overall structure is stable, the surface is smooth and flat, without sharp burrs, which can effectively protect the cable sheath and avoid wear and damage during laying and use. The uniformly arranged porous structure can accelerate air circulation, timely dissipate the heat generated by cable operation, reduce the hidden heat hazards of power lines, ensure long-term stable operation of power, communication, and control cables, and effectively extend the service life of cables. The product can be equipped with various anti-corrosion surface treatment processes such as galvanizing and spraying, and is suitable for various scenarios such as indoor computer rooms, office buildings, intelligent buildings, and light industrial workshops. Standardized specification design is suitable for various conventional wiring schemes, with complete supporting accessories, easy installation, and simple operation and maintenance. It meets the construction standards of various civil buildings and industrial engineering at home and abroad, and is the preferred product for high-density wiring projects.
