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.

There are three kinds of cable trays: ladder type, tray type and trough type, each of which is suitable for different installation environments, and various cable tray materials are also different.

The ladder cable tray is suitable for cables below 10kV, which can be used for indoor and outdoor cable overhead laying or cable trenches and tunnels in industrial and mining enterprises and buildings such as electric power, metallurgy, petrochemical, textile, electromechanical and other industrial and mining enterprises.

The tray cable tray is suitable for installation in the workshop or other public places, with a beautiful appearance, and is divided into two forms: empty tray and perforated tray.

The trough cable tray is made of galvanized steel plate or cold-rolled steel plate stamping and folding forming, and can form a fully enclosed bridge after the cover plate, which can prevent dust, fire, smoke pollution and mechanical damage, and has anti-interference function for telecommunication computer and control wires and cables.

Usually the models of cable tray are divided into: trough type, tray type, ladder type.

The different materials of the cable tray are divided into: galvanized tray, stainless steel 304 tray, aluminum alloy 1060 tray.

The surface treatment process is divided into: fireproof baking paint, electrostatic spraying, hot-dip galvanizing (hot-dip galvanizing) Common specifications are: (width * height * thickness is: national standard thickness).

300mm*100mm*

400mm*100mm*

500mm*100mm*

600mm*200mm*

800mm*200mm*

1000mm*150mm*

1200mm*200mm*, etc.

It is petroleum, generally divided into these types: 1. Tray cable tray, it has the advantages of light weight, large load, beautiful appearance, simple structure, convenient installation, etc., it is suitable for the installation of power cables, and is 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 bridge, hot-dip galvanized sheet bridge, electro-hot galvanized bridge, electrostatic spraying bridge, fireproof paint (coating) bridge, anti-rust paint bridge, fireproof and flame retardant bridge, etc.

Specifications and models of cable trays.

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).

Thickness: non-standard) national standard).

Are you a sign of rust soon after the bridge is installed? How to choose the material of the bridge? If you don't choose well, it will rust soon when you install it, and the bridge materials on the market are:

Galvanized, sprayed, fireproof, stainless steel, aluminum alloy, hot-dip galvanized, FRP and so on. The above is also our most common material Having said so much is it not a little dizzy, remember the following points 1, in general, in an ordinary indoor environment, galvanizing or electrostatic spraying is used, and electrostatic spraying is a little better than galvanizing. 2, places with strong corrosive environment, hot-dip galvanizing, stainless steel, FRP, hot-dip galvanizing are widely used, recommended 3, places with fire protection requirements, directly choose fireproof bridge 4, need anti-electromagnetic interference, anti-shielding interference places, such as network computer room, the first choice of aluminum alloy bridge 5, ** dangerous places, construction can not be fired, FRP bridge is your best choice, or do not understand?

To sum it up, look at this picture.

The cable tray is divided into trough type, tray type, ladder type, grid type and other structures, which are composed of brackets, brackets and installation accessories. The bridge frame in the building can be erected independently, and can also be attached to various buildings (structures) and pipe gallery self-support, which should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance, and all parts need to be galvanized. If the bridge installed in the open air outside the building is known to be near the sea or belongs to the corrosion area, the material must have the physical characteristics of anti-corrosion, moisture resistance, good adhesion and high impact strength.

The types and models of cable trays are mainly divided into: trough type, ladder type, and tray type.

1. Trough cable tray: The shape of the trough cable tray is fully sealed, like a box, and the whole is sealed.

2. Ladder cable tray: the appearance is like a ladder shape, and the middle is manually welded to fix the crossbar reinforcement, and the bearing capacity is better than that of the trough type and tray type, so it is mainly used for laying large-span power cables, because the large-diameter power cable emits a large amount of heat at the same time in the transmission spring, and the ladder cable tray is more suitable and has good air permeability.

3. Land car tray cable tray: The shape of the tray tray is semi-sealed, although it is the same as the trough tray as a whole, the only difference is that the bottom of the tray is perforated, which is conducive to heat dissipation, so it is called a tray cable tray.

People in the industry know that the size and thickness of the cable tray are mainly determined by the weight and quantity of the cable.
