The design and installation of cable trays requires that the cable tray design and selection process should be based on the type and number of cables in each system of the weak current, and reasonable and practical bridges should be selected. (1) Affirm the width of the bridge: According to the number of cables laid, the diameter of the cable and the distance between the cables, confirm the type and specifications of the cable bridge, the length of the support arm, the length and the spacing of the pillars, the trough cable bridge is made of a whole steel The conceptual difference between the trough-shaped component and the tray is that the height and width ratio are different. The tray is shallow and wide. The trough-type cable tray has a certain depth and closeness. The width and number of layers of the bridge. (2) Affirmative installation method: According to the setting premise of the occasion, affirm the fixing method of the bridge frame. When laying the cascade cable bridge horizontally, it is advisable to select the best span to support according to the load curve. When laying vertically, the fixed distance should not be greater than 2m. Choose suspension type, upright type, side wall type or confusing type. The connecting parts and fasteners are usually supplied as supporting equipment. Others, according to the structure of the bridge, choose the cover plate that responds to the folding. (3) Draw a flat and cross-sectional view of the cable tray, and a space map should be drawn in some parts, and a material table should be listed. (4) Affirmation bias: According to the building layout plan, combined with the air conditioner pipeline and electrical pipeline installation settings, convenient maintenance, and the density of cable routing to affirm the best route of cable tray. Indoors, the FRP cable bridge has both the rigidity of the metal bridge and the toughness of the FRP bridge, with good corrosion resistance and strong aging resistance. It can be widely used in petroleum, chemical industry, electric power, light industry, television, telecommunications, etc. As far as possible, it should be erected along the walls, columns, beams and floors of the building.If an integrated pipe corridor is used, it should be erected in parallel on one side or above the pipeline. If you borrow other pipe racks, you need to set up (support) columns by yourself. (5) Load calculation: Calculate the weight of the cable per unit length on the longitudinal section of the cable bridge backbone.
