In order to minimize the occurrence of cable damage, ensure the normal laying of cables, and ensure the normal operation of cables, it is necessary to adjust the specifications of cable trays according to different cables and geographical environments. The purpose is to do a good job in cable laying. So what does the specification of Jinan cable tray mean? What factors should we consider when selecting specifications?
Generally speaking, the selection of specifications refers to the selection of the width and height of the bridge. At this point, the diameter of the laid cable and the specifications of the cable itself must be considered as the selection criteria for laying, which is also a point to consider when laying.
During the cable laying process, the laying plan can be adjusted according to the actual installation needs, starting from reality and reserving space for future practical applications is also very important.
There are many types of cable trays, and currently there are five common ones in the market. Each type has advantages such as light weight, low cost, and comfortable installation. Some of them still look beautiful on the surface. Of course, each type of cable tray has similar positions and its own advantages.
From the perspective of production materials, there are metal cable trays and fiberglass cable trays, which must be selected according to the actual situation.
In addition, it should be noted during installation that when the bridge is laid horizontally, the height from the ground should generally not be less than 2.5m. When the cable tray is laid in double layers, in order to meet the requirements of heat removal, maintenance, and impact prevention, a certain distance should be left between the fixed layers of the cable tray. When the cable tray is laid parallel to various pipelines, its spacing must comply with relevant regulations.
The seismic support quality of cable trays must comply with the current relevant standards and specifications. When laying cable trays horizontally, the span of the support point is generally 1.5~3m. When laying vertically, the fixed fixed spacing should not exceed 2 meters. The difference in height between the two adjacent cable tray trailing arms should not exceed 10 mm, and the vertical error of the vertical centerline of the two adjacent cable tray trailing arms should not exceed 20 mm.
That's all for the factors that should be considered when selecting cable tray specifications. We hope you can prepare well and avoid most of the problems. For more information on cable trays, please visit our website Consult and take a look!
