Precautions for erecting polymer cable trays

    When laying polymer cable bridges in fully enclosed bridges, pay attention to these issues:
     1, clean and clean. A good working environment is whether the work can be carried out in an orderly and effective manner. Therefore, we must clean the line pipe in advance and clean the dirt and water in the pipe.
    2, orderly and not chaotic. When laying cables or wires inside a fully enclosed bridge, we must first make sure that the cables or wires are aligned, and if they can be bundled, it is better. In this process, it should be noted that the cable must not be twisted, jointed, flattened, broken, and severely scratched.
    3. Basic insulation work is to be done well, and work such as sealing and waterproofing cannot be ignored.
    4, we can have a clear identification on a variety of cable lines, which can be more convenient for our subsequent maintenance and maintenance.
    When the tray trunking bridge is under construction, there are sometimes some problems. If these problems cannot be solved, it will have a very serious impact on our use, for example. It can't be laid parallel with some pipes during construction. If it can't be avoided, then the following protective measures should be taken.
    1. If it is laid in parallel with a corrosive liquid pipe, the tray trough bridge needs to be laid above the corrosive liquid pipe.
    2. The bridge should be laid under the heat pipe.
    3. If the flammable and explosive gas in the pipeline is heavier than air, then we must install the bridge above the pipeline.
    4. If the flammable and explosive gas in the pipeline is lighter than air, then we must install the bridge below the pipeline.
    These are the problems that should be paid attention to when the polymer cable tray is laid in parallel with the pipeline, so that in the subsequent use, the impact on us will not be too large.
