Professional Cable Tray Manufacturer

When the cable bridge is installed on the ground level of the building, the support needs to be installed first. according to the standard, the bridge can not touch the ground directly, which is easy to cause leakage accident or vibration damage. 
The commonly used bridge specifications are 100*50mm, 100*100mm, 200*50mm, etc., the common width of the bridge is 100mm, 200mm, 300mm, 400mm, etc., and the commonly used height is 50mm, 100mm, 150mm and so on. 
The following is a description of the relevant content for your reference. 
1. Bridge bracket when the wires in the cable tray are laid vertically, the cable wires should be fixed on the bracket of the bridge tray at an interval of 1.5 meters. 
When laying horizontally, it should be fixed at the beginning and end of the cable, at turns and at intervals of 3 to 5 meters. 
The cable tray bracket and bracket can be laid on the process pipe rack, under the floor, on the wall, in the cable ditch, and the installation forms of the cable tray bracket and bracket include suspension type, vertical type, sidewall type and so on. 
2. The national standards of cable tray include "JB/T 10216-2000 cable tray for electronically controlled distribution" (abbreviated as 2000 national standard) and "JB/T 10216-2013 cable tray for electronically controlled distribution" (abbreviated as 2013 national standard). 
The 2000 national standard includes the calculation method of strength and stability of bridge structure, uniformly distributed load and conductivity experiment. 
The 2013 national standard includes the number of ex-factory inspection samples and the determination array and the classification of unqualified type inspection. 
3. for the cable tray with the same specification and different structure, the price of the trough cable tray is more expensive than that of the ladder cable tray, and the price of the tray cable tray is higher than that of the trough cable tray. 
The inside and outside of the cable tray should be smooth and smooth, without edges, and there should be no distortion, warping and other deformations. the specifications and models of the insulated conductors used must meet the design requirements and carry a certificate. 
4. Tray width the commonly used widths of cable tray are 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, 800mm, 1000mm and so on. 
The widths of 200mm, 300mm and 400mm are the most common. 
The customer chooses which material to use according to the need of bearing capacity. 
Generally, the flat steel outer bracket is selected below the cable tray width 400mm, and the angle steel outer bracket is selected when the cable tray width is above 400mm. 
5. Bridge height Cable Bridge should fill in: name + model + arm length + arm height when compiling the pick-up list of the horizontal arm of the wall. 
For example: "arm (5) JY-TB105,L=200,H=50", (indicates the length of the arm 200mm, the distance between the arm and the wall is 50mm. 
Cable tray hanger should fill in: name + height H + cross pole length L, for example: suspension frame, DK-101-50mm 25 represents the suspension frame suitable for 50x 25 bridge (excluding through wire). 
6. The tray bracket can be directly installed on the wall, or the suspension bracket can be installed on the floor first, and then the cable tray bracket can be installed on the suspension bracket. 
The above are the standard requirements of the cable tray bracket and the common specifications, width and height of the cable tray compiled by Beijing Weiye. If you have any questions about the relevant knowledge, you can call the consultation hotline.
