Tray Type Aluminum Alloy Bridge
A tray-type cable tray, also referred to as a perforated cable tray, is a trough-shaped structure consisting of a base plate and side plates with heat dissipation holes. It is a common type of cable tray system.
Key Functions and Features:
Support and Protection:
It provides reliable mechanical support for cables, shielding them from physical damage and environmental factors during operation.Effective Heat Dissipation:
The perforated design promotes airflow, allowing heat generated by cables to dissipate efficiently. This helps lower operating temperatures and extends cable service life.Broad Applicability:
Suitable for both power and control cable installations, it is widely used across industries such as petroleum, chemical, power generation, light industry, broadcasting, and telecommunications.Ease of Installation:
With a clean aesthetic, straightforward structure, and user-friendly design, it simplifies the installation process and improves construction efficiency.
Thanks to these advantages, tray-type cable trays have become an essential component in modern cable laying systems.
Introduction of the product：
Tray-type cable trays, characterized by their heat dissipation holes, are primarily categorized based on structural features. The following are the main types:
Perforated Tray:
Featuring a perforated base, this design facilitates effective cable heat dissipation. It is particularly suitable for applications where thermal management is critical, such as installations involving large-diameter cables or high-temperature environments.
Additionally, tray-type cable trays can be further classified by material and anti-corrosion coating, including galvanized steel, stainless steel, aluminum alloy, as well as treatments like color steel composite coating and hot-dip galvanizing. These material and coating options enhance the trays' adaptability to various environmental conditions, ensuring long-term structural stability and durability.
In summary, tray-type cable trays have gained widespread adoption in the field of cable laying due to their distinctive structural design and functional advantages.
Production process：
Application:
Tray-type cable trays are widely employed in power engineering, communication systems, construction projects, and industrial facilities, offering an efficient and reliable cable management solution for various applications. Specifically, they are suitable for cable laying in general environmental conditions, particularly in scenarios where power cables require effective heat dissipation—such as indoor, low-humidity, and low-pollution areas. The open design ensures adequate natural ventilation, helping to prevent accelerated cable aging caused by overheating. These trays are also extensively used across industries including petroleum, chemical, power generation, light industry, broadcasting, and telecommunications, where they provide secure support and lasting protection for cables.
In addition, tray-type cable trays support flexible system expansion. They can be easily extended with additional branches or connected to other types of cable trays as project requirements evolve, accommodating diverse installation layouts and future modifications.
In summary, thanks to their functional advantages and broad applicability, tray-type cable trays have become an essential component in modern cable management systems.
