We know that the cable tray in the building can be erected independently or laid on various buildings (structures) and pipe rack supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance. As power equipment, the construction and installation of cable tray in Shandong Province is a very important work and the focus of quality monitoring. How can we do better? Pay attention to these six points when installing cable tray!
1. Cable tray is a wiring project without the guidance of professionals. Under the product specifications, many manufacturers have different production methods. The lack of universality is a major disadvantage. In the design and selection, it is necessary to reasonably select the accessories to be used according to the requirements of the project.
2. When cable tray and power cable tray are used together, power cable and weak current cable need to be installed separately, and the middle needs to be separated by a partition.
3. When using weak current cables and low voltage cables together, it should be ensured to choose the type of weak current cable with shielding function
4. If it enters the building from an outdoor cable tray, its slope shall not be less than 1/100, and when it crosses with electrical equipment, its clear distance shall not be less than 0.5m.
5. When the cable tray crosses the electrical equipment, the clear distance between them shall not be less than 0.5m.
6. It is necessary to draw the starting point, turning point, branch point, lifting point, and endpoint of the bridge frame on a parallel diagram. The coordinate points and dimensions must be accurately identified. Draw a lateral diagram of the cable tray laying axis, which can make the budget statistics of materials more accurate.
The above is the little knowledge explained by the cable tray manufacturer. Welcome to pay more attention to our website http://www.yeeones.com ！ I will explain new content points to you every day!
