Knee to the classification and procurement points of cable trays?

The cable tray mainly includes the surface part, wall thickness, welding, etc.

The cable tray is available in ladder and trough type, and attention is paid to length and load bearing in procurement and design.

There are four main classifications of cable trays: cascade cable tray, tray cable tray, trough cable tray, and long-span cable tray.

The matters that need to be paid attention to when specific procurement are roughly as follows:

According to the building to determine the direction and length, load calculation, determine the width of the bridge, protection, etc.

Selection of cable tray type and variety:

1. When the cable network that needs to be shielded from electrical interference or has the requirement of protecting the external (such as corrosive liquid, combustible dust and other environments), the (FB) trough composite anti-corrosion shielded cable tray (with cover) should be selected

2.In highly corrosive environments, (F) composite epoxy resin anti-corrosion and flame-retardant cable trays should be used. The same material should be used for the bracket and bracket to improve the service life of the tray and accessories, and the cable tray. In the environment or outdoor places that are prone to dust accumulation and other needs to be covered, it is advisable to add a cover.

3. In addition to the above conditions, tray type, trough type, stepped type, glass anti-corrosion flame retardant cable tray or steel ordinary cable tray can be selected according to the environmental and technical requirements of the site. In the environment or outdoor places that are prone to dust accumulation and other needs to be covered, it is advisable to add a cover.

4. In the public passage or outdoor crossing road section, the bottom of the bottom step should be added with a backing plate or a tray should be used in the section. When the large span spans the public passage, the load capacity of the bridge can be increased according to the user's requirements or the row frame can be selected.

5. Composite bridge (FB) should be selected for large span (>3m).

6. Composite epoxy resin bridge (F) should be used outdoors.

The type of cable tray mainly depends on the weight of the cable and the use environment and other factors, and the following provides us with some commonly used cable tray types on the market as a reference:

Trough cable tray: A trough cable tray is a hermetically sealed cable tray, box-like shape, used to lay cables.

Ladder cable tray: It looks like a ladder shape together, and the center is welded with a crossbar to reinforce the support, which makes it light weight, low cost, extremely strong bearing capacity and good air permeability.

Tray cable tray: Traybed cable tray is a semi-sealed cable tray, which is very similar to the posture of trough cable tray, and it has a hole in the bottom for heat dissipation.

The following is a guide to the commonly used standards in the market

The standard is suitable for: trough tray (C), ladder tray (T), tray tray (P) (special standards can be customized by contact).

The advantages and disadvantages of cascade, tray and trough cable trays: the cascade type merge tray has good ventilation performance, and is not dustproof and interference-proof. Trough and tray cable tray have dustproof and anti-interference performance.

4. Large-span cable tray.

At present, the large-span cable tray is generally assembled from pultruded FRP profiles, which is suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, it has the advantages of long service life (the general design life is 20 years), easy installation and low cost (the specific gravity is only 1 4 of carbon steel, no fire is required during construction, and the length of a single bridge can reach 8 meters, or even longer), easy cutting, no maintenance and so on.

5. Combined cable tray.

Combined cable tray is a new type of cable tray and is the second generation product in the cable tray series. It is suitable for the laying of various projects, various units and various cables, and it has the characteristics of simple structure, flexible configuration, convenient installation and novel form.

As long as the combined cable tray adopts three base types of width mm, it can form the cable tray of the size you need, and it does not need to produce bends, tees and other accessories can be arbitrarily steered, widened, and led up and down according to the on-site installation. In any part, no need to punch holes, welding can be used to lead out with a tube. It can not only facilitate engineering design, but also facilitate production and transportation, and more convenient installation and construction, and is the most ideal product for cable tray at present.

Generally, there are these types:

1. Tray cable tray, it has the advantages of light weight, large load, beautiful appearance, simple structure, convenient installation, etc., it is not only suitable for the installation of power cables, but also suitable for the laying of control cables. It is the most widely used in petroleum, chemical industry, electric power, light industry, television, telecommunications, etc. 2. Cascade cable tray, ladder cable tray has the advantages of light weight, low cost, unique shape, easy installation, heat dissipation, good air permeability, etc., it is suitable for the laying of general straight and light large cables, especially for the laying of high and low power cables.

The cable tray should be protected by the protective cover plate when crossing the area that is susceptible to external mechanical damage and in the open air. When the cable tray or ladder frame is branched, it can be connected with various bends. 3. Trough cable tray is a fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables and other high-sensitivity systems of control cables, and the protection of cables in heavy corrosion environments has a good effect.

4. FRP, aluminum alloy and long-span cable tray. There are also cable trunking, wire screens, trough bends, tees, crosses and straights, as well as brackets and hangers. 5. According to the different surface treatments, it is divided into:

Hot-dip galvanized tray, hot-dip galvanized sheet tray, electro-hot-dip galvanized tray, electrostatic spraying tray, fireproof paint (coating) tray, anti-rust paint tray, fireproof flame retardant tray, etc.

Shanghai Changpeng Metal Products **** tells you that first determine the environmental conditions: there are generally three kinds of environmental conditions: corrosive environment, normal environment, and special environment.

According to the cable load and the environment of the installation place of the bridge, the load curve of the bridge is used as the basis to determine the type and specification of the bridge, the spacing of the columns, the length of the supporting arm, the level of the bridge, the length of the column, etc.

The trough cable tray is a fully enclosed cable tray, which is suitable for laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems for shielding interference and protection of cables in heavy corrosive environments.

The tray cable tray has the advantages of light weight, large load, beautiful shape, simple structure and convenient installation, which is not only suitable for the installation of power cables, but also suitable for the laying of control cables.

The cascade cable tray is suitable for the laying of large diameter cables, especially for the laying of high and low voltage power cables.

The combined cable tray can be combined at will according to the actual situation of the installation site, which is suitable for occasions where the installation environment is more complex and there are more requirements for the space change of the cable tray tray.

The large-span cable tray is limited by the conditions of the installation site, and can not be provided with more supporting arms and hangers, and the bridge must have a large support and crane span.

The material of the cable tray is a common problem in the engineering design of the cable tray. According to the division of materials, cable trays are mainly made of steel, glass fiber reinforced plastic and aluminum alloy. FRP cable tray is characterized by light weight, and the weight is only 1 4 of carbon steelIt has good water resistance and corrosion resistance, and is suitable for chemical plants.
