Capacity of power cable tray

    Our life is inseparable from electricity, so the bridge where the cable is placed is The necessities of the project. So what is the carrying capacity of the power cable tray? Cable tray manufacturers give you an analysis.
    Power cable trays are used as cables to support cables and have limited load-carrying capacity. Therefore, the use of power cable bridges must not be overloaded, otherwise it will cause serious deformation and affect not only It is beautiful in appearance and affects the safety of the cable and may even cause a safety accident.
    When the power cable tray is installed indoors, in order to ensure the straight and beautiful appearance of the bridge, the horizontal load deformation is generally controlled within 4 mm, we can Select the width of the cable tray and the required deformation of the horizontal load of the bridge, and find the load characteristic curve of the bridge in the corresponding structure. If the deformation requirements are not met, you can increase the height of the bridge side or reduce the support spacing. Thereby meeting the requirements.
    The power cable tray is stamped from thin steel plate, with limited load capacity, which will be deformed due to overload of the bridge, which not only affects the aesthetics of the bridge, but also affects the safe operation of the cable. Normally, the load carrying capacity of the cable tray is represented by the load characteristic curve of the cable tray. As can be seen from the load curve, the load capacity is related to the bridge size and support distance, corresponding to the same support distance and bending deformation. the amount. The side height is large and the bearing capacity is large. When the load capacity is the same, the bending distance of the cable tray of the same specification is small and the bending deformation is small.
    When using the power cable tray, be sure to pay attention to his carrying capacity and not cause a safety accident.
