Ladder-Type Cable Trays

The CQ1-T series ladder-type cable tray is improved and designed based on relevant domestic and foreign data. It features light weight, low cost, a unique structure, convenient installation, and excellent heat dissipation and ventilation. Suitable for laying large-diameter cables as well as high and low-voltage power cables.

Tray-Type Cable Trays

Tray-type cable trays are widely used in industries such as petroleum, petrochemicals, light industry, and telecommunications. They offer advantages including light weight, high load-bearing capacity, an aesthetic appearance, a simple structure, and easy installation. Suitable for both power cable installation and control cable laying.

Long-span cable trays

Currently, long-span cable trays are generally assembled from pultruded FRP profiles. They are suitable for power cables, control cables, lighting cables, and accessories. Compared with steel cable trays, they have the following advantages: long service life (general design life of 20 years), convenient installation, low cost (specific gravity is only 1/4 of carbon steel, no open flame required during construction, and length can reach 8 meters or longer), easy cutting, and maintenance-free operation.

Channel-Type Cable Trays

Channel-type cable trays are fully enclosed cable troughs. Suitable for laying control cables of high-sensitivity systems such as computer cables, communication cables, and thermocouple cables. They provide excellent shielding against interference for control cables and protection for cables in highly corrosive environments.

Advantages and Disadvantages of Ladder-Type, Tray-Type, and Channel-Type Cable Trays

Ladder-Type Cable Trays: Excellent ventilation performance, but not dustproof or anti-interference.

Channel-Type & Tray-Type Cable Trays: Dustproof and anti-interference.

Modular Cable Trays

Modular cable trays are a new type of cable tray, serving as the second-generation product in the cable tray series. They are suitable for cable laying in various projects, units, and scenarios. Featuring a simple structure, flexible configuration, convenient installation, and a novel design.

Modular cable trays can be assembled into the required size using three basic models with widths of 100mm, 150mm, and 200mm. Without the need for prefabricated elbows, tees, or other accessories, they can be freely turned, widened, or branched up/down according to on-site installation requirements. Pipes can be led out at any position without drilling or welding. It not only facilitates engineering design but also simplifies production, transportation, and installation—making it an ideal product among Galvanized cable trays.
