Information
Cable trays are part of the power system. What should you pay attention to when using cable trays?
 
1. The surface of the cable tray should be treated with cold plastic coating computer gray paint.
 
2. The distance between the hangers installed horizontally of the cable tray is not more than 1.6m, the spacing of the vertically mounted brackets is not more than 1.6m, and one bracket bracket is added at each column position;
 
3. The manufacturing process of the bridge frame is reasonable. The surface of the finished bridge frame is smooth and smooth without burr. The gap of the docking error is less than 1.5mm. The bridge cover is butted, there is no warping phenomenon, the buckle is welded firmly, the weld is flat, and each bridge is between Must be equipotential bonding;
 
4. During the construction of the electric house, there should be monitoring of the personnel of the power distribution room, and the construction work can only be carried out after the safety of the power distribution room personnel has been checked and confirmed;
 
5. The corners of the cable trays need to be protected by rubber; the installation should be straight and straight, firm and reliable, and meet the standards and requirements for the installation of bridges in the power industry;
 
6. Cable vertical mounting section requires the addition of cable bundling fixtures for vertical cable installation and cable section support;
 
7. The bending radius of the bridge bend shall not be less than the minimum allowable bending radius of the cable inside the bridge.
 
8. The bolts between the bridge frame and the bracket and the bolts of the bridge connecting plate are fixed and fastened, and the nut is located outside the bridge frame;
 
9. The horizontal height of the cable tray installation is 4.0m from the ground. The height of the original replacement section bridge is unchanged, but the connection should be reasonably tidy;
 
10. The outdoor bridge frame enters the opening of the room, and the cutting size is appropriate. After the project is completed, it should be sealed tightly.
 
The above is the handling of the cable tray during construction. It is known that the handling of the cable tray is also convenient for the maintenance and maintenance of the cable tray in the future.
