Structural Design
- This cable tray is mainly assembled with two longitudinal side rails - commonly made of C-channel, U-channel or customized profiles - and evenly spaced rungs. The connection between components is completed via full-length welding or high-strength mechanical fasteners.
- The side rails ensure longitudinal bending rigidity, while the rungs form a sturdy ladder-shaped framework. Thanks to this open structural design, the tray weighs far less while retaining high load-bearing capacity, which makes it ideal for long-span overhead installation scenarios.
- Common manufacturing materials include hot-dip galvanized steel, electro-galvanized steel, stainless steel and aluminum alloy. To adapt to indoor, outdoor and harsh corrosive environments, optional surface treatments such as powder coating and secondary hot-dip galvanizing are available to enhance corrosion resistance.
Key Advantages
Excellent Heat Dissipation Performance
The open grid structure enables unobstructed air flow around installed cables. It can quickly dissipate the heat generated during cable operation, effectively reducing conductor temperature, slowing down the aging speed of cable insulation layers, and prolonging the overall service life of cables. It is the preferred tray type for high-current and high-heat cables such as power cables and VFD cables, as it greatly avoids heat accumulation inside the cable layout system.
Reliable Load-Bearing Capacity
The truss-style combination of side rails and rungs endows the product with superior mechanical properties. It can stably bear the static load of heavy cables and resist short-term dynamic impact forces. By adjusting the side rail size, rung spacing and material thickness, products that meet different load grade requirements can be customized, with no risk of structural deformation or collapse during use.
Simple Installation and Convenient Maintenance
The large open gaps between rungs allow staff to directly observe each installed cable. Inspectors can easily check cable sheath conditions, connector temperature and the overall layout of cable lines. Adding, removing or replacing cables can be done without dismantling the entire tray section, and cable ties and supporting accessories can be installed effortlessly. In addition, the lightweight structure and standardized connecting parts facilitate on-site cutting, assembly and suspension construction, effectively shortening the overall project construction cycle.
Typical Application Scenarios
