The full name of a rigid structural system consisting of tray-type, pallet-type or cascade straight segment, bending-type, three-way and four-way components, as well as bracket (arm-type bracket) and hanger, etc., which is equipped with a tight connection support cable (hereinafter referred to as bridge)
Classification of cable Bridges
1. Cascade cable tray
The design of CQ1-T cascade cable tray is improved according to the related information at home and abroad. It has the advantages of light weight, low cost, unique shape, convenient installation, heat dissipation and good air permeability. It is suitable for laying large diameter cable, high and low voltage power cable.
2. Tray cable tray
Tray cable tray is one of the most widely used in petroleum, chemical industry, light industry and telecommunication. It has light weight, large load and beautiful shape
Cable tray (20 pieces), simple structure, easy installation and other advantages. It is suitable for both power cable installation and control cable laying.
3. Trough cable tray
Trough cable tray is a fully enclosed cable tray. It is most suitable for laying computer cable, communication cable, thermocouple cable and other control cable of high sensitive system. It has good effect on shielding interference of control cable and protecting environment cable in heavy corrosion.
The advantages and disadvantages of cascade type, tray type and trough type cable bridge: cascade type cable bridge has good ventilation, no dust, no interference. Trough - type and tray - type bridge with dust - proof, anti - interference performance.
4. Large-span cable tray
At present, large-span cable tray is generally assembled by pultrusion of FRP profiles, which is suitable for power cables, control cables, lighting cables and accessories. Compared with iron bridge, it has the advantages of long service life (generally designed life of 20 years), convenient installation and low cost (the proportion is only 1/4 of carbon steel, the construction does not need to fire, the single bridge length can reach 8 meters, or even longer), convenient cutting and no maintenance.
5. Composite cable bridge
Composite cable tray is a new kind of tray, which is the second generation of cable tray series. It is suitable for laying all kinds of projects, all kinds of units and all kinds of cables. It has the characteristics of simple structure, flexible configuration, convenient installation and novel form.
As long as the combined cable bridge adopts three types of 100, 150 and 200mm wide, it can form the cable bridge of the size you need. In any place, no holes, welding can be used to pipe out. It is not only convenient for engineering design, production and transportation, but also more convenient for installation and construction
