No matter what kind of goods we choose, we have to deal with them carefully.
Next, I would like to introduce to you the relevant content-what are the key points for the selection of perforated cable tray?
Main points of product selection:
1.Cable trays, wire slots and their supports and hangers are used in corrosive environment, they should be made of corrosion-resistant rigid materials, or anti-corrosion treatment should be adopted, and anti-corrosion treatment should meet the requirements of engineering environment and durability.
2.in the section with fire prevention requirements, the cable bridge can add fire-resistant or non-flammable plates, nets and other materials to the cable ladder and tray to form a closed or semi-closed structure, and take measures such as painting fireproof coating on the surface of the bridge and its supports and hangers, its overall fire resistance should meet the requirements of the relevant national codes or standards.
3.When selecting the load grade of the cable ladder, the working uniformly distributed load of the cable tray should not be greater than the rated uniformly distributed load of the selected cable tray. If the actual span of the support and hanger of the cable tray is not equal to 2m, then the working uniformly distributed load should meet the requirements.
4.Under the condition of meeting the corresponding load, the specifications and dimensions of various components and hangers shall match the straight line segment and bend series of pallet and ladder rack. 5.When selecting the bending or leading up and down devices of the perforated cable tray, it should not be less than the minimum allowable bending radius of the cable in the cable tray.
6.The selection of the width and height of the cable ladder should meet the requirements of the filling rate. Under normal circumstances, the filling rate of the cable ladder should be 40% 50% for the power cable and 50% 70% for the control cable, and the engineering development margin of 10% to 25% should be reserved.
