1. Cascade cable tray
CQ1-T type stepped cable tray is improved and designed according to relevant domestic and foreign materials. It has the advantages of light weight, low cost, unique shape, convenient installation, good heat dissipation and good ventilation. It is suitable for laying cables with larger diameters in general, and for laying high and low voltage power cables.
2. Tray-type cable tray
Tray-type cable tray is the most widely used in petroleum, chemical, light industry, telecommunications and other fields. It has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation. It is suitable for both the installation of power cables and the laying of control cables.
3. Trough cable tray
The trough cable tray is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has a good effect on the shielding interference of control cables and the protection of environmental cables in heavy corrosion.
The advantages and disadvantages of the stepped cable tray, the tray type and the grooved cable tray: the stepped bus cable tray has good ventilation performance, and is not dust-proof or interference-proof. The slot-type and tray-type wire bridges have dust-proof and anti-interference performance.
4. Large-span cable tray
At present, long-span cable trays are generally assembled from pultruded FRP profiles, which are suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, it has a long service life (general design life is 20 years), convenient installation and low cost (the specific gravity is only 1/4 of carbon steel, no hot work is required during construction, and the length of a single bridge can reach 8 meters, or even longer), convenient cutting, no maintenance and other advantages.
5. Combined cable tray
The combined cable tray is a new type of cable tray, which is the second generation of the cable tray series. It is suitable for the laying of various projects, various units and various cables. It has the characteristics of simple structure, flexible configuration, convenient installation and novel form.
