Main purposes of cable tray

In our daily life, we often come into contact with the purpose of cable tray mainly in three aspects: supporting cables; Protective cable; And management cables.

(1) Support cables

Cable tray supports cable attachment and support on buildings (structures) through its own structural characteristics, or independently supports cables through tunnels or caves, underground, air, etc., mainly for supporting cables. It plays the role of cable skeleton, and the cable connection is completed on the cable tray. Because most cables are flexible structures, they cannot be laid independently, and the characteristics of rigid structures are that cable trays can be used to support cables.

(2)Protect cables

The cable is like blood. The main function is to carry out various power transmission, information transmission, information control, etc. The cable tray is like a blood vessel wall, which separates the cable from the outside, wraps it, lifts it, and effectively aligns it. Cable protection.

For example, large span cable trays can be used when laying power cables. It can effectively prevent the cable from sagging due to its own weight, prevent the cable from being directly exposed to the atmosphere, directly isolate the sun, fog, rain, snow, wind and other factors to the cable, and effectively extend the service life of the cable. Cable.

Slotted cable tray is used to arrange computer cables, communication cables, thermocouple cables and other control cables of high sensitivity systems. They have good effects in shielding interference from control cables and cable protection in severely corrosive environments.

When the fire-resistant cable tray encounters 700 ° high temperature, it can ensure the effective operation of the cable within 30 minutes to 1 hour. It can be used in high-temperature workshop or building environment with high fire rating requirements. Fire engineering cables.

HDG cable tray has high corrosion resistance and moisture resistance. It adopts a closed structure. When used in coastal areas and severely corroded factories and mines, it can protect cables from corrosion and moisture.

Cable trays of different materials and structures have different functions, and cable protection is diversified. Suitable cable tray can be selected according to local conditions, and cable protection requirements under different conditions and environments can be fulfilled.

(3) Manage cables

By using the function of cable bridge to manage cables, various electric energy (mainly electric power) engineering and intelligent engineering cables can be scientifically arranged in the construction project, building space can be reasonably used, reasonable structural design can be achieved, and simple construction is convenient. Space saving and beautiful layout are conducive to maintenance and replacement.

The role of cable tray in cable management is mainly reflected in the following points:

It is conducive to cable layout. The characteristics of the cable tray itself, cable management is different from the traditional cable buried, wall to wall, overhead, etc., single beam multi beam or even tens of thousands of bundles of cables, which can centralize cable management and have more cable management levels. According to the functional requirements of different building facilities, standard cable control can be carried out, which is less affected by space and construction equipment. It can be arranged along the corner of the ceiling, such as columns and columns, to make space use more reasonable and cable layout more free. The cable design is more convenient.

It is conducive to cable maintenance and replacement. The cable tray is easy to install and remove. It is easy to operate when cables need to be repaired and maintained. For the cable to be replaced, only the main part of the cable tray needs to be removed, and the installation can be resumed, and the building structure can be easily damaged.

It is helpful to organize and manage different cables. The development of science and technology has accelerated the updating of building equipment, promoted the improvement of building intelligent system, and put forward higher requirements for cable engineering. Cables also have various characteristics. The density of cables is increasing, and the types of cables are also increasing.Power cables, information control cables, signal transmission cables, etc. can effectively control the organization through scientific cable bridge combination, so that the cables are clear, orderly, efficient and efficient.
