托盘式桥架具有重量轻、载荷大、造型美观、结构简单、安装方便等优点。托盘式电缆桥架即适用于动力电缆的安装，也适合于控制电缆的敷设。下面 山东桥架厂家来浅谈桥架在安装中要知道的事情。

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.桥架、电缆跨越变形缝无补偿措施。

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

2.桥架内电缆无标志(出入口和转角处和分支处)。

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

3.桥架内电缆固定不牢,有的无固定(特别是垂直桥架内)。

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

4.桥架和其它管道，特别是暖气、空调管净距过近，不符合要求；一般管道0.4m（平行），0.3m（交叉）；保温热力管道0.5m(平行),0.3m(交叉);非保温热力管道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.非镀锌钢板桥架连接接头处无跨接,或跨接不良、观感差。

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.桥架和配电箱、盘、柜等无跨接接地,桥架支架接地数量不足2处。

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

7.桥架板连接处,镀锌钢板没有两螺栓为防松螺帽或垫圈,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.桥架板防腐处理不良,有锈蚀,观感不良.

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

9.桥架板连接处螺栓螺母在内侧。

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

10.桥架内高压电缆和弱电电缆共用一个桥架。

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

此外还要注意，桥架内电缆排列无序,且有绞接现象。桥架内电缆过多，超过净面的40%一电力电缆,50%一控制电缆。桥架支架距离长，有变形、吊筋多，少固定支架，不能承受水平力。等等，更多事项就来我们网站 //www.comprepyme.com咨询吧！

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.
