For cable tray, its carrying capacity and working load distribution are two important indicators. The carrying capacity of the cable is mainly reflected by the thickness of the material, so the main way to improve its carrying capacity is to increase the thickness of the material. As for the working load distribution, the more uniform the better, so that the load sharing of each part improves the overall carrying capacity of the bridge and also improves its service life. Of course, different materials are used in different environments. If in a severely corrosive environment, generally choose FRP or aluminum alloy as the main raw material for bridge production, which can improve its corrosion resistance, and can also be achieved by different surface treatment. According to the different grades, it can be divided into hot-dip galvanizing, thermosetting powder electrostatic spraying, spraying, galvanizing and other treatments.

What are the problems in the installation process of cable tray?

Cable tray as a powerful tool for easy operation and use, has been widely used in the construction industry However, the quality of the products produced by individual manufacturers is poor, and the construction personnel did not explain how to use them correctly, which caused great losses. Langfang Dongda Metal Products Co. In order to avoid unnecessary casualties and property losses, some matters should be noted when installing cable bridges.

Cable bridge

First of all, to determine the direction of Anhui cable bridge, you must determine the better route of the cable bridge according to the drawings designed for you by the construction engineer, combined with the air conditioning piping and gas piping setup for easy subsequent maintenance, as well as the density of cable routing. In rooms, they should be framed as parallel as possible along the walls, columns, beams and floors of the building to one side or above the ducts, and consideration should be given to branching the ducts downwards as far as possible to avoid crossovers. If there are no other pipe frames to borrow, they must be erected.

Next, load calculations are carried out to calculate the mass of the trunking of the Anhui cable bridge and the larger range it can withstand so that losses are small. Later, the width of the bridge is determined. According to the number of discharged cables, cable diameter and cable spacing, the type of cable bridge, the specification of the arm length, the length and spacing of the struts, the width of the bridge and the number of layers are determined.
