What issues should be considered when selecting a polymer cable tray?

    Polymer cable trays have become a part of our lives. Lack of tools to support electrical safety, then what should you pay attention to when purchasing cable trays?
    1. Use environmental factors to choose: air corrosive, aesthetic requirements.
    The polymer cable tray is used in a complex environment and its performance is unstable. Therefore, the material of the Wuhan cable tray should be considered first. Under normal circumstances, the cable trays made of the superior steel plates are most suitable. The surface of such bridges is treated with anti-corrosion treatment such as electroplating or spraying, and the anti-corrosion performance is enhanced, which is more suitable for the working environment and longer in use.
    If the environment used in the polymer cable tray is relatively corrosive, we recommend that you choose a cable tray made of aluminum alloy. The polymer cable tray can also be applied to places with high requirements for fire prevention. When applying, it is better to add materials such as fire-resistant or flame-retardant plates to the bridge to improve the fire resistance of the polymer cable tray. Finally, anti-electromagnetic interference performance is also a consideration when choosing a polymer cable tray. Semi-enclosed or closed cable trays can reduce electromagnetic interference, such as trough cable trays, suitable for applications. In places where there is a corresponding requirement. 2. Wire and cable requirements: Closed cable trays are suitable for laying computer cables, communication cables, thermocouple cables and other control cables for highly sensitive systems; ladder bridges are suitable for high and low voltages. The laying of the power cable.
    3. Specification selection, size and number of loading cables.
    4, load performance.
    5. Installation options: horizontal installation, vertical installation, turning (available for bending), confluence (three-way, four-way available). . .
    6. Costs    Finally, the polymer cable bridge factory reminds: there are more cable bridge manufacturers on the market, the market is not competitive, when Party A does not When specifying the brand, in selecting the cable tray manufacturer, it is necessary to pay attention to whether the manufacturer has the production capacity, whether the qualification is complete, the quality of the product, and so on. . . There should be no distortion, black spots, rust, etc. on the surface of the bridge.
