1. Cascade cable tray.

CQ1-T cascade cable tray is designed according to relevant data at home and abroad. It has the advantages of light weight, low cost, unique shape, easy installation, heat dissipation and good ventilation. It is suitable for the laying of cables with large diameters, and is suitable for the laying of high and low voltage power cables.

2. Trough cable tray.

A trough cable tray is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables, and other control cables for 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 cascade and trough cable trays: the cascade assembly cable tray has good ventilation performance, and is not dustproof and interference-proof. Trough and tray cable tray have dustproof and anti-interference performance.

The difference between ladder cable tray and trough cable tray is that ladder cable tray is attributed to open tray, while trough tray is attributed to fully enclosed tray. Their advantages and their application are not the same in the natural environment. Therefore, in the case of selecting a cable tray, it is necessary to choose a cable tray that is suitable for today's natural environment.

The cascade bridge is light in weight, low in cost, unique in shape, easy to install, good in heat dissipation and air permeability, and is suitable for laying cables with large diameters, especially for the laying of high and low voltage power cables. Trough cable tray is a kind of fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems, etc., which has a good effect on the shielding interference of control cables and the protection of cables in heavy corrosive environments. The shield of Changpeng trough cable tray is supplied with the trough, and other accessories are common with cascade and tray tray.

1.The appearance difference between trough tray and tray cable tray: trough tray refers to the non-perforated tray structure type cable tray, and tray tray refers to the perforated tray structure type cable tray.

2.The performance difference between trough tray and pallet tray: trough tray is fully enclosed, and its main function is to shield interference and resist corrosion. It has a good effect on the protection of cables in the shielding interference and heavy corrosion environment of control cables.

The surface treatment of the pallet tray can be divided into three types: electrostatic spraying, galvanizing and hot-dip galvanizing according to user needs. In the heavy corrosive environment, it can be treated with special anti-corrosion, and there are many waist-shaped holes at the bottom of the pallet tray to facilitate heat dissipation.

3.The application difference between trough cable tray and tray cable tray: trough tray: suitable for laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems.

Tray cable tray is one of the most widely used in petroleum, chemical industry, electric power, light industry, television, telecommunications, etc. It has the advantages of light weight, large load, beautiful appearance, simple structure, easy installation, etc., it is suitable for the installation of power cables, and also suitable for the laying of control cables.

1. Non-perforated cable tray tray (trough cable tray):

The trough cable tray is a fully enclosed type of tray, and its appearance design is the same as that of the closed box, because of its sealed characteristics, its anti-interference effect is very strong, especially suitable for laying calibration machine cables, telecommunication network cables, thermal resistance cables and even other high-sensitivity system software frequency conversion cables to shield off noise and heavy erosion of cable maintenance in the natural environment.

2. Perforated cable tray tray (tray cable tray):

The tray tray is a semi-sealed type, which is very similar to the appearance of the trough bridge, which has the advantages of light weight, large load, beautiful shape, simple structure and convenient installation. It is suitable for both the installation of power cables and the laying of control cables.

The difference between trough tray and ladder is that:

The product weight of the ladder bridge is lighter, it is more convenient and fast to install in the construction process, and the transportation and loading and unloading process will be faster, so in the construction, if the quality is relatively light, it can make the construction of the construction unit more convenient.

For construction, easy installation is also necessary. It is also necessary to ensure that the shape of the product is good, and only in this way can the construction effect be good.

The trough tray is a fully enclosed cable tray with no openings, so it is poor in heat dissipation, while the bottom of the trough of the ladder tray has many waist-shaped holes, and the heat dissipation performance will be relatively better. It can shield cable interference and protect cables in heavily corrosive environments, but ladder bridges cannot.

The advantages of trough bridge are light structure, low cost, simple construction, flexible wiring, installation standard, beautiful appearance, generally can be erected independently in the building, can also be attached to various buildings and pipe gallery supports, so according to the geographical environment or the different installation environment, the selection of cable tray is also targeted.

The main function of the ladder bridge is also good ventilation and heat dissipation, which is most suitable for those large-diameter cables, which is conducive to improving the cable operating environment.

There are heat dissipation holes at the bottom of the tray tray tray, but there is no trough type! Due to the opening of the heat dissipation hole, the thickness of the tray tray plate should be thicker!
