Professional Cable Tray Manufacturer

Based on the characteristics of its own structural foundation, the Cable tray supplier connects the cables to buildings that can be supported and fixed, or to independent supporting cables, sometimes in caves, in the air or on the ground, and the supporting cables are its main function. 
Let's take a look at the installation steps of the cable tray. 
Let's take a look. 
1.When the slotted long-span cable tray enters the building from the outside, the outward slope of the bridge shall not be less than 1Comp100. 
2.When the bridge frame crosses with the electrical equipment, the net distance between it is not less than 0.5m. 
3.When two groups of cable bridges are laid in parallel at the same height, the net distance between them is not less than 0.6m. 
4.when drawing the route of the bridge on the parallel diagram, it is necessary to indicate the coordinates or positioning dimensions and elevations of the starting point, the end point, the turning point, the branch point and the lifting point of the bridge. if the axial side diagram of the laying of the bridge can be drawn, the material statistics will be more accurate. 
Straight line section: indicate the full length, the number of layers of the bridge, elevation, model and specification. 
Turning point and branch point: indicate the type and specification of the turning plate used. 
Rise and fall section: indicate the elevation change, or it can be expressed by local large sample drawing or section view. 
5.Bridge support point. 
Such as post, bracket or non-standard support, spacing of frame, installation mode, model specification, elevation, may agree to be listed on the plane, or can be marked by different sections, single lines or large sample drawings. 
6.the location and mode of cable lead-down. Generally speaking, a large number of cables can be guided by vertical bending plate and vertical lead-up, and a small number of cable can be guided by guide plate or guide pipe, indicating the lead-down mode. 
7.The cable tray should be more than 2.2 meters above the ground, the top of the bridge should not be less than 0.3 meters from the ceiling or other obstacles, the width of the bridge should not be less than 0.1 meters, and the filling rate of the cross section in the bridge should not exceed 50%. 
8.When the cable is vertically laid in the cable tray, it should be fixed on the bracket of the bridge at the upper end of the cable and at an interval of 1.5 meters, and when laid horizontally. 
Fix the cable at the beginning, tail, turn and at intervals of 3 to 5 meters. 
9.When set up in the ceiling, the opening surface of the slot cover should maintain a vertical clearance of 80 mm, and the utilization rate of the wire slot section should not exceed 50%. 
10.The cable placed in the slot can not be tied, the Cable tray supplier in the slot should be straight, the cable in the slot should be straight and should not cross as far as possible, the cable should not overflow the slot, where the cable goes in and out of the slot. 
The turn should be tied and fixed. 
The vertical slotted cable should be fixed on the cable bracket at intervals of 1.5 meters. 
11. When laying wires in horizontal and vertical bridges and vertical slots, the cables should be tied up. 
4.24 pairs of pairs of cables shall be used as bundles, and 25 or more pairs of trunk cables, optical cables and other signal cables shall be divided and tied according to the type, diameter and number of cables. 
The binding spacing should not be more than 1.5 meters, the buckle spacing should be uniform and the tightness should be moderate. 
12. When the cable tray is laid horizontally, the support spacing is generally 1.5-3m, and the distance fixed on the building structure should be less than 2m in vertical laying. 
The above are the installation steps of the Cable tray supplier. In the project construction, the bridge should determine the construction plan according to the factors such as economic rationality, technical feasibility and operation safety, so as to fully meet the requirements of construction installation, maintenance and cable laying.
