How to wiring the cable bridge? Here are seven wiring rules of the cable bridge summarized by Jinan Cable Bridge Company. I hope you can read them carefully and really help us all!

一、几组电缆桥架在同一高度平行安装时，各相邻电缆桥架间应考虑维护、检修距离。

1. When several groups of cable bridges are installed in parallel at the same height, the maintenance and repair distances between adjacent cable bridges should be considered.

二、在电缆桥架布线时，其电缆不应有黄麻或其他易延燃材料外护层。

2. When cables are cabled indoors, jute or other flammable materials shall not be used as external protective layer for cables.

三、电缆桥架水平安装时，宜按荷载曲线选取佳跨距进行支撑，跨距一般为1.5～3m。垂直敷设时，其固定点间距不宜大于2m。

3. When the cable bridge is installed horizontally, the optimum span should be selected according to the load curve, and the span is generally 1.5-3 M. When laying vertically, the distance between fixed points should not be more than 2m.

四、在有腐蚀或特别潮湿的场所采用电缆桥架布线时，应根据腐蚀介质的不同采取相应的防护措施，并宜选用塑料护套电缆。

4. When cables are used in corrosive or especially humid places, corresponding protective measures should be taken according to different corrosive media, and plastic sheathed cables should be selected.

五、电缆桥架不宜安装在腐蚀性气体管道和热力管道的上方及腐蚀性液体管道的下方，否则应采取防腐、隔热措施。

5. Cable bridge should not be installed above corrosive gas pipeline and thermal pipeline and below corrosive liquid pipeline, otherwise anti-corrosion and heat insulation measures should be taken.

六、在电缆桥架上可以无间距敷设电缆，电缆在桥架内横断面的填充率：电力电缆不应大于40％；控制电缆不应大于50％。

6. Cables can be laid on the cable bridge without spacing. The filling rate of the cross section of the cable in the bridge frame should not be greater than 40% for power cables and 50% for control cables.

七、电缆桥架（托盘）水平安装时的距地高度一般不宜低于2.50m，垂直安装时距地1.80m以下部分应加金属盖板保护，但敷设在电气专用房间（如配电室，电气竖井、技术层等）内时除外。

7. The height of cable tray should not be lower than 2.50M when it is installed horizontally, and the metal cover should be used to protect the part below 1.80m when it is installed vertically, except when it is laid in the special electrical room (such as distribution room, electric shaft, technical layer, etc.).
