What effect has the tray type bridge achieved

Tray type cable trays have achieved various practical effects in the field of cable laying through their design and material technology.

The tray type bridge adopts an open tray structure, with a large width between the bottom and side plates, which can accommodate multiple cables to be laid in parallel. Its load-bearing capacity is significantly higher than that of traditional trough type bridge. Its material can be selected from stainless steel, aluminum alloy, or galvanized steel, which ensures strength and reduces weight, making it suitable for centralized deployment of large capacity cables.

Through plug-in design, fast installation is achieved, and in 2025, its splicing structure is enhanced with positioning plates and bolt limit plates to improve stability and construction efficiency. The open structure facilitates cable layering and avoids clutter, especially suitable for clean wiring of short distance communication lines, while supporting flexible expansion. The bottom and side plates are evenly equipped with heat dissipation holes to dissipate the heat generated during cable operation, avoiding the accumulation of hot air such as the high temperature problem of power cables. The heat dissipation performance is better than that of fully enclosed trough type cable trays. Part of the perforated bridge frames add flexible film at the holes to balance heat dissipation and dust prevention requirements. The semi enclosed structure provides dust and falling object protection. Although it is not as fully enclosed and shielded as the trough bridge, the protection level can be further improved by adding a cover plate.

Suitable for laying high current cables, such as substations and power plants, carrying high power demands. The layout of communication lines in data centers and telecommunications rooms, utilizing their heat dissipation properties to protect data cables. Stainless steel material or hot-dip galvanizing process can be used for cable trays in heavy corrosive environments such as chemical and petroleum industries to extend their service life. By layered installation and reasonable wiring, electromagnetic interference between cables can be reduced, and the reliability of communication lines can be improved. Quick installation modular design supports plug-in splicing, reducing traditional welding steps and lowering construction complexity.

The open structure facilitates cable maintenance and replacement, with high efficiency in troubleshooting, especially suitable for communication lines that require frequent adjustments. Compared to fully enclosed trough type cable trays, tray type cable trays have lower material and construction costs, making them suitable for general-purpose projects with limited budgets. The tray design with simple lines meets the requirements of modern industrial aesthetics and is commonly used in commercial and office buildings.

The tray type bridge achieves a balance between load-bearing, heat dissipation, protection, and construction efficiency through an open structure, perforated heat dissipation technology, and modular design, becoming a universal solution in the fields of power, communication, and industry. The core of its effectiveness lies in its flexible adaptation to different needs. For example, the punched type focuses on heat dissipation, while the non perforated type strengthens protection. Users can choose the configuration according to their specific environment. In the future, with the upgrading of material technology, its performance boundaries will be further expanded.
