Porous cable tray is a universal cable support equipment that balances load-bearing performance, heat dissipation effect, and lightweight advantages. It is widely used in data centers, intelligent engineering, municipal weak current systems, factory renovation, and overseas foreign trade infrastructure projects. On the basis of retaining the overall structural strength of the bridge, the product optimizes its own weight through scientific drilling technology, effectively reduces the overall load, reduces the bearing pressure of building ceilings, brackets, and support arms, adapts to construction scenarios such as large-span ceiling installation and high-altitude wiring, and improves the safety and adaptability of engineering construction. The regular hollow hole positions not only optimize ventilation and heat dissipation, but also facilitate construction personnel to quickly locate and fix points, simplify the installation process, and improve on-site construction efficiency. The product has fine workmanship, compliant dimensional tolerances, high splicing fit, and a neat and orderly overall wiring appearance, which can meet the aesthetic construction requirements of modern buildings. At the same time, the porous structure facilitates later line inspection, ventilation, and dehumidification, reducing line faults caused by moisture and dust accumulation, and lowering long-term operation and maintenance costs. The product supports batch supply of standard specifications and can also be adjusted according to project requirements to meet the engineering needs of different wiring densities and installation environments. It has strong universality and practicality and is suitable for various conventional electrical wiring projects at home and abroad.
