How much is the price of cable tray and how to choose.

How much is a meter of bridge is not calculated, but the seller has a ** for different specifications and materials of bridge. What you have to consider is whether the bridge he gives you meets your requirements, such as thickness, material, whether it has a cover plate, whether it meets the fire protection requirements, whether it is equipped with screws, ground wire braided copper belt, support and hanger and other issues. Finally, I can say **.

The specifications are different, of course, they are not the same, and some depend on what materials are used.

1. Determine environmental conditionsThere are generally three kinds of environmental conditions: corrosive environment, normal environment, and special environment.

2. According to the direction of most cables, you can walk along the columns, beams and floors indoors, and along the process pipeline as much as possible outdoors.

3. Calculate the load: calculate the weight q and the total load g of the cable per unit length on the cable tray cross-section

g total = n1q1 + n2q2......nnqn

where: q1, q2, q3......qn is the unit weight of each cable (kg m).

n1·n2·n3……nn indicates the number of cables of the same type.

g total 4, select the tray according to the cable load and the environment of the bridge installation, based on the load curve of the bridge, to determine the type and specification of the bridge and the spacing of the column, the length of the supporting arm, the level of the bridge, the length of the column, etc.

5. Determine the fixing mode of the bridge according to the cable direction and the installation environment; Suspension, upright, (both forms can be fixed on one side or both sides), wall side, etc.

6. The hierarchical arrangement and interlayer distance of various cables on the cable tray.

The arrangement of the cable tray level is: the weak current control cable is at the top layer, and then the general control cable, low-voltage power cable, and high-voltage power cable are arranged in the following order: as shown in the following table: this arrangement is conducive to shielding interference, ventilation, heat dissipation, etc.

First determine how many cables there are, whether to consider the increment in the future, what model to choose according to the use environment, and then determine the length and corner, and send an inquiry letter to the manufacturer. Praise for it!

It's about 150 yuan.

If you help, give it a good review.

There are many types, depending on what kind of cable you want to use, and what kind of cable you want to make.

3. All ordinary cable trays are divided into trough cable trays, tray cable trays, cascade cable trays, grid trays and other structures, which are composed of brackets, brackets and installation accessories. Can be erected independently, can also be laid on a variety of buildings (structures) and pipe gallery supports, reflecting the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance, all parts need to be galvanized, installed in the open air outside the building bridge, if it is near the sea or belongs to the corrosion area, the material must have anti-corrosion, moisture resistance, good adhesion, high impact strength physical characteristics:

trough cable tray; Thickness; Yuan meters.

trough cable tray; Thickness; Yuan meters.

trough cable tray; Thickness; Yuan meters.

1) Thickness - plate area = weight * unit price + processing loss - waste residual value + coating cost = main material cost, 2) labor costs, machinery costs, taxes and facilities (plant rent) office financial costs, logistics.

Because the ** of the plate often fluctuates, the ** of the bridge will also change, but it will change according to the ** of the bridge market.

Stainless steel cable tray:

Stainless steel Minzhao cable tray is made of stainless steel plate, not bridge rust steel material model is divided into: 201 304 316 stainless steel, as we all know, stainless steel has anti-corrosion, anti-rust, anti-wear and other characteristics, and stainless steel is one of the stronger metal materials used in construction projects, so stainless steel cable tray also directly shows its perfect performance, not only anti-corrosion, fireproof, heat insulation, moisture-proof, etc., but also has a long service life.

Stainless steel cable tray model types: stainless steel trough type, sprocket stainless steel ladder type, stainless steel tray type, stainless steel large span, stainless steel mesh format, etc., the above tray models can be made of stainless steel materials.

Stainless steel tray specifications:

Width 60 * Height 40 * Thickness; 1 meter

Width 60 * height 60 * thickness; 1 meter 80

Width 80 * height 80 * thickness; 1 meter

Width 100 * height 80 * thickness; 1 meter 118

Width 150 * height 80 * thickness; 1 meter

Note: Due to the large number of specifications, not all of them are listed, the above are some commonly used specifications unit price, according to the requirements of special sizes can be made.

It depends on what material and what specifications to serve, to know what the price of the bridge you want. Pure noisy galvanized material bridge ** is not expensive.

200*100*yuan.

300*100*yuan meter.

400*100*yuan meter.

400*150*yuan.

The cable tray should be laughed at according to the specifications of the copper bar installed inside, and there are three-phase three-wire and three-phase four-wire, which is not the same. Because the price of copper is relatively expensive, the ** of the bridge is also more expensive.
