The polymer bridge partition, directly speaking, is to add a partition in the middle of the bridge It can be added in trough, ladder and tray type. (Premise not to process on site by hand, because some precautions are not clear, it is recommended to let the manufacturer carry out professional processing)
    Use: When the engineer designs the cable of different models On the same bridge, they can be isolated by a partition to avoid signal collisions.
    Separating power cables and low voltage instrumentation signal cables in the same cable tray. For example, if the 300*150 cable tray needs to be partitioned, then its representation method is generally: (200+100)*150, which means that the 300mm wide cable tray is divided into two areas of 200mm wide and 100mm wide. .
    The fire circuit and the ordinary circuit, the same load of the two-way cable should be laid separately, and the partition should be added when laying in the same bridge. Fire lines have fire protection requirements and must be laid in refractory tanks. If the ordinary cable and the fire-fighting cable are laid in the same tank, the load flow rate is reduced a lot (minimum 0.38), which will increase the investment of the ordinary distribution circuit cable. Therefore, it is more reasonable to lay the ordinary cable separately in the cable frame. If fire-fighting uses mineral insulated cables, fire and non-fire can be laid in the ladder frame, then there is no such problem, just set the partition.
    According to different needs, there are generally two types of partitions, and the installation method is different:
    1. Fixed partition, that is, in the trough , weld the partition according to the position or size requested by the customer. Disadvantages: Poor flexibility, no change in design if there is a change in construction. Advantages: The construction side saves time and labor; 2 Active partition:
    2. Separate the partitions, machine the screw holes at the bottom of the partitions, and use bolts to connect with the tray body. Disadvantages: Time-consuming, labor-intensive, screw-eye processing of the required position of the tank during construction. Advantages: High flexibility, changing design at any time. Before using the partition, first determine the size and type of the bridge according to the number of cables, diameter, and separation distance. Note:
    1 When selecting the width of the cable tray, there should be some spare space to reserve for the future addition of cables and partitions.
    2. When there are fewer power cables and control cables, they can be installed on the same cable tray, but the power cable and control cable should be separated by a partition.
    Cable trays are divided into trough, tray and ladder type, net format and other structures, consisting of brackets, support arms and mounting accessories. There are also different separator models for different cable trays. The bridges in the building can be erected independently or attached to various building (construction) structures and pipe rack supports. The structure should be simple, beautiful in appearance, flexible in configuration and convenient in maintenance. All parts must be galvanized. , installed in the open-air bridge outside the building.
