托盤式橋架具有重量輕、載荷大、造型美觀、結構簡單、安裝方便等優點。托盤式電纜橋架即適用于動力電纜的安裝，也適合于控制電纜的敷設。下面山東橋架廠家來淺談橋架在安裝中要知道的事情。

Tray type bridge has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation. Tray type cable tray is suitable for both power cable installation and control cable laying. Next, Shandong bridge manufacturers will talk about what to know in the installation of bridge.

1.橋架、電纜跨越變形縫無補償措施。

1. There are no compensation measures for bridge and cable crossing deformation joints.

2.橋架內電纜無標志(出入口和轉角處和分支處)。

2. There is no sign for the cable in the bridge (entrance, exit, corner and branch).

3.橋架內電纜固定不牢,有的無固定(特別是垂直橋架內)。

3. The cables in the bridge are not firmly fixed, and some are not fixed (especially in the vertical bridge).

4.橋架和其它管道，特別是暖氣、空調管凈距過近，不符合要求；一般管道0.4m（平行），0.3m（交叉）；保溫熱力管道0.5m(平行),0.3m(交叉);非保溫熱力管道1.0m(平行),0.5m(交叉)。

4. The clear distance between the bridge and other pipes, especially the heating and air conditioning pipes, is too close to meet the requirements; General pipeline 0.4m (parallel) and 0.3m (cross); Thermal insulation pipeline 0.5m (parallel) and 0.3m (cross); Non insulated thermal pipes are 1.0m (parallel) and 0.5m (cross).

5.非鍍鋅鋼板橋架連接接頭處無跨接,或跨接不良、觀感差。

5. There is no bridging at the connection joint of the non galvanized steel bridge, or the bridging is poor and the appearance is poor.

6.橋架和配電箱、盤、柜等無跨接接地,橋架支架接地數量不足2處。

6. Bridge and distribution box, panel, cabinet, etc. have no jumper grounding, and the number of bridge support grounding is less than 2.

7.橋架板連接處,鍍鋅鋼板沒有兩螺栓為防松螺帽或墊圈,不符要求。

7. At the connection of bridge plate, no two bolts of galvanized steel plate are locking nuts or washers, which is not in conformity with the requirements.

8.橋架板防腐處理不良,有銹蝕,觀感不良.

8. The anti-corrosion treatment of bridge plate is poor, with corrosion and poor appearance

9.橋架板連接處螺栓螺母在內側。

9. The bolts and nuts at the connection of bridge plate are inside.

10.橋架內高壓電纜和弱電電纜共用一個橋架。

10. High voltage cables and weak current cables in the bridge share the same bridge.

此外還要注意，橋架內電纜排列無序,且有絞接現象。橋架內電纜過多，超過凈面的40%一電力電纜,50%一控制電纜。橋架支架距離長，有變形、吊筋多，少固定支架，不能承受水平力。等等，更多事項就來我們網站http://www.yeeones.com咨詢吧！

In addition, it should be noted that the cables in the bridge are disorderly arranged and twisted. There are too many cables in the bridge, 40% of which are power cables and 50% of which are control cables. The bridge support has long distance, deformation, many hanging bars, few fixed supports, and can not bear horizontal force.
