Installation of polymer cable trays
Edit:Shan Dongfang Kai Polymer Materials Co., Ltd.   PublicDate:2019-07-29

     Compared with the windy and sandy spring, hot and rainy summer and cold winter, there is no wind and sand in autumn, more sunny days and more pleasant temperatures. Whether it is indoor work or outdoor work, it is more appropriate. Don't worry about the weather and temperature, this is one of the main reasons why polymer cable tray manufacturers recommend that you install the bridge in the fall.
    In winter, the temperature is low and foggy weather often occurs. Bridges installed outside should have good rust and corrosion resistance, which requires bridges installed in autumn to have corresponding protective properties.
    Polymer Cable Tray Installation Process:
    Positioning and Discharging→Pre-embedded Iron or Expansion Bolt→Support, Hanging, Bracket Installation→Terrace Installation →Protective grounding installation
    The length of the steel cable tray of the straight section is more than 30m. The length of the aluminum or glass steel cable tray exceeds 15m. The expansion joint should be provided. The compensation device is arranged across the expansion joint. The bridge with the expansion joint can be used.
    2. The bolts between the bridge frame and the bracket and the bolts of the bridge connecting plate are not leaked. The nut is located outside the bridge. When the aluminum alloy bridge is fixed with the steel bracket, there are corrosion measures against each other to prevent electrical corrosion. Generally, the asbestos pad can be placed.     3. The bridges laid in the shaft and crossing different fire zones shall be in accordance with the design requirements and have fire isolation measures. The cable bridges may be laid in the electrical shafts and fixed by angle steel.     4. When the cable tray passes through the firewall and the fireproof floor slab, fire isolation measures shall be taken to prevent the fire from igniting along the line; the fire barrier wall and board shall be reserved with the reserved hole for civil construction, and the retaining angle steel shall be pre-buried at the hole. According to the number of layers and the number of cables laid, L50×50×5 angle steel is used as the fixing frame, and the fixed cabinet is welded on the retaining angle steel. It is also possible to first make the frame to be installed in the wall when the masonry or concrete is poured in the civil construction. In the board.
