With the increasing number of construction projects such as large office buildings, financial malls, hotels, and stadiums in China, the reasonable layout of the weak current system is undoubtedly a key consideration for architects in the entire project. The emergence of cable trays has played a reasonable, stable, and safe role in the layout of weak current systems. Therefore, the purchase of cable trays cannot be ignored.

A cable tray is a support for supporting and laying cables. Trough-type cable trays are widely used in engineering. Whenever cables need to be laid, cable trays are required. As a supporting project of wiring engineering, there is currently no special standard for guidance, and the specifications and schemes of several manufacturers lack versatility. Therefore, in the design and selection process, the appropriate cable tray should be reasonably selected according to the type and quantity of cables in the weak current system. Cable trays have the characteristics of various types, wide applications, high strength, light structure, low cost, simple construction, flexible wiring, standardized installation, and beautiful appearance.

Trough-Type Cable Trays

Cable trays are divided into trough-type, tray-type, ladder-type and other structures, consisting of supports, arms, and installation accessories. When selecting, attention should be paid to whether all parts of the cable tray meet the requirements of serialization, generalization, and standardization. Cable trays in buildings can be erected independently or attached to various buildings (structures) and pipe gallery supports, and should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. For cable trays installed outdoors in buildings, if they are near the seaside or in a corrosive area, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion, and high impact strength.
