Precautions for cable tray installation:
1. The general layout of the bridge should be short, economical, reasonable and safe, and should meet the requirements of construction, installation, maintenance and cable laying.
2. The bridge has sufficient bending stiffness and compressive strength to provide safe and reliable support for cables.
3. After cable laying, the deflection of the bridge shall not exceed 1/200 of the span of the bridge. When the span of the bridge is ≥ 6000 mm, the deflection shall not exceed 1/150 of the span of the bridge.
4. The bridge shall be installed on the buildings (such as walls, columns, beams, floors, etc.) under construction, and closely cooperate with the civil engineering discipline.
5. When the bridge is installed together with the manufacturing process pipe support, the bridge should be placed on one side of the pipe support.
6. When the bridge is built parallel to various pipelines, the net spacing shall meet the following requirements:
(1) When the bridge is built parallel to the general manufacturing process pipes (such as compressed air pipes, etc.), it shall not be less than 400mm.
(2) When the bridge is built parallel to the corrosive liquid pipeline, it shall not be less than 500mm.
(3) The bridge is not suitable to be installed in parallel below the pipeline transporting corrosive liquid or above the pipeline transporting corrosive gas. When it cannot be prevented, it shall not be less than 500 mm. And it shall be separated by anti-corrosion partition.
(4) The bridge shall be built parallel to the heat supply pipeline. When the heat supply pipeline has thermal insulation material, it shall not be less than 500mm, and when there is no thermal insulation material, it shall not be less than 1000mm.
(5) The bridge is not suitable for installation on the parallel surface above the heat supply pipe. When it cannot be prevented from being installed on the parallel surface above the heat supply pipe, it should not be less than 1000mm, and effective heat insulation measures should be taken in between.
