随着社会的发展，电缆桥架的应用越来越广泛，但是你知道电缆桥架布线的规则有哪些吗，今天小编就一起来和大家了解一下。
With the development of society, the application of cable tray is more and more widely, but do you know the rules of cable tray wiring? Today, let's get to know.
电缆桥架的布线规则是什么？
What are the routing rules of cable tray?
1.在室内采用电缆桥架布线时，电缆不应有黄麻或其他易燃材料作为外护套。
1. When the cable tray is used for indoor wiring, the cable shall not have jute or other flammable materials as the outer sheath.
2.电缆桥架水平安装时，应根据支撑荷载曲线选择合适的跨度，跨度一般为1.5 ~ 3m。垂直敷设时，固定点间距不大于2m。
2. When the cable tray is installed horizontally, the appropriate span should be selected according to the support load curve, and the span is generally 1.5 ~ 3M. When laying vertically, the distance between fixed points shall not be more than 2m.
3.在有腐蚀或特别潮湿的地方采用电缆桥架布线时，应根据不同的腐蚀介质采取相应的防护措施，并适当选择塑料护套电缆。
3. When cable tray is used for wiring in places with corrosion or special humidity, corresponding protective measures shall be taken according to different corrosive media, and plastic sheathed cables shall be selected appropriately.
4.当几组电缆桥机架平行安装在同一高度时，应考虑相邻电缆桥机架之间的维护和检修距离。
4. When several groups of cable bridge frames are installed in parallel at the same height, the maintenance and overhaul distance between adjacent cable bridge frames should be considered.
5.电缆可以无间距地敷设在电缆桥机架上。桥架横截面电缆填充率：电力电缆不应超过百分之40;控制电缆不应大于50。
5. The cable can be laid on the cable bridge frame without space. Cable filling rate of bridge cross section: power cable shall not exceed 40%; The control cable shall not be greater than 50.
6.电缆桥架(托盘)水平安装高度一般不应小于2.50米，垂直安装距离地面1.80米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。
6. The horizontal installation height of cable tray (tray) shall not be less than 2.50M, and the vertical installation distance below 1.80m from the ground shall be protected by metal cover plate, except when it is laid in the special electrical room (such as distribution room, electrical shaft, technical floor, etc.).
7.电缆桥架不应安装在腐蚀性气体管道和热力管道上方和腐蚀性液体管道下方，否则应采取防腐和隔热措施。
7. The cable tray shall not be installed above the corrosive gas pipeline and heat pipeline and below the corrosive liquid pipeline, otherwise, the anti-corrosion and heat insulation measures shall be taken.
8.下列不同电压、不同用途的电缆不应敷设在同一层桥架上：
8. The following cables with different voltages and different uses shall not be laid on the same layer of cable tray:
1)应急照明和其他照明用电缆。
1) Cables for emergency lighting and other lighting.
2)lkV以上和1kV以下的电缆。
2) Cables above 1kV and below 1KV.
3)双向电力电缆，用于向同一路径的主负载供电。
3) Two way power cable is used to supply power to the main load in the same path.
4)强弱电电缆。如果因情况需要安装在同一层桥机架上，应使用隔板隔开。
4) Strong and weak current cables. If it needs to be installed on the same floor of the bridge frame due to the situation, it should be separated by partition.
9.电缆桥架与各种管道平行或交叉时，净距应符合表DQ4-1的规定。
9. When the cable tray is parallel or crossed with various pipelines, the clear distance shall meet the requirements of table dq4-1.
10.电缆桥框架穿过防火墙和防火楼层时，应采取防火隔离措施。
10. When the cable bridge frame passes through the fire wall and fire floor, fire isolation measures shall be taken.
11.电缆桥架中的电缆应在头端、尾端、转弯处，每隔50m，无编号、型号、起止点等。
11. The cables in the cable tray shall be at the head end, tail end and turning point, with no number, model, starting and ending point, etc. every 50m.
12.电缆桥架电缆应固定在下列部位。垂直敷设时，电缆的上端和每隔1.50 ~ 2m。水平敷设时电缆的首、尾两端、转弯及每隔5～10m处。
12. The cable tray cable shall be fixed at the following parts. When laying vertically, the upper end of the cable and every 1.50 ~ 2m. When the cable is laid horizontally, the two ends of the head and tail, the turn and every 5-10m.
