What is the installation process of aluminum alloy cable tray?

The installation process of aluminum alloy bridge is not so complicated. Friends who don't know how to install it can take a look at this article. 

The following is a detailed introduction to you, including the inspection of the appearance, the location of the reinstallation and so on. 

The appearance Cable tray supplier shall be carried out before the installation of the cable tray, and there shall be no defects such as missing welding, cracks, burning through, etc., and there shall be no defects such as uneven galvanizing and ash hanging on the surface of the coating. 

When entering the construction site, the bridge shall also submit the factory certificate, inspection report and technical appraisal documents to meet the pre-installation acceptance requirements. 

1.The height from the ground of the bridge laid horizontally in the installation position should be more than 2.5m. In order to protect the heat dissipation of the bridge, a certain distance should be maintained between the bridges laid on multiple layers, and the bridges laid in parallel should also have a clear distance according to the requirements. 

2.Installation of supports and hangers when the cable tray supports and hangers that meet the current technical standards are laid horizontally, the support span is generally 1.5-3 meters. 

When the vertical laying distance of the fixed bridge is not more than 2m, the horizontal height difference between the adjacent bridge supports should be less than 10 mm, and the distance between the two adjacent bridge supports from the vertical centerline should be less than 20 mm. 

Cable tray is an auxiliary project in wiring engineering. 

At present, there is no corresponding specification guidance, and there is no common specification between different manufacturers. 

Therefore, in the design and selection, the appropriate bridge should be reasonably selected according to the type and number of cables in each weak current system. 

Installation position of aluminum alloy bridge and installation items of support and hanger

1.The direction is determined according to the arrangement of electrical pipes and air-conditioning pipes, the reasonable route of cable tray is determined to facilitate maintenance. 

If laid indoors, it should be erected along walls, columns, beams and floors. 

If a pipe corridor can be used, it should be erected in parallel on one side of the pipe to avoid crossing with other pipes. 

If there are no other channels to borrow, you must build your own pillar. 

2.The calculation load mainly calculates the weight of the cable per unit length on the longitudinal section of the trunk. 

3.The width of the bridge is determined according to the number, diameter and spacing of the cable, determine its model and specification, as well as the length and spacing of the bracket and strut, as well as the number and width of the bridge. 

4.The fixing mode of the installation mode Cable tray supplier should be determined according to the actual situation of the site and the setting conditions, including suspended type, vertical type, sidewall type and mixed type. 

In addition, the corresponding cover plate, connector and fastener should be selected according to the bridge structure, and there is no need to choose. 

The above is the summary of the installation of the bracket and hanger in the installation process of aluminum alloy bridge, as well as the determination of direction, load, bridge width and installation mode. I hope this article can help you!
