5、 On stainless steel cable trays, cables can be laid without spacing, and the filling rate of the cable in the cross-section of the tray should not exceed 40% for power cables; Control cables should not exceed 50%.

六、不锈钢桥架(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。

6、 When stainless steel cable trays are installed horizontally, the height from the ground should generally not be less than 2.50m. When installed vertically, metal cover plates should be added to protect the parts below 1.80m from the ground, except when laid in electrical dedicated rooms (such as distribution rooms, electrical shafts, technical floors, etc.).

七、不锈钢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。

7、 Stainless steel cable trays should not be installed above corrosive gas and heat pipelines, or below corrosive liquid pipelines. Otherwise, anti-corrosion and insulation measures should be taken.

八、下列不同电压，不同用途的电缆，不宜敷设在同一层桥架上：

8、 The following cables with different voltages and purposes should not be laid on the same layer of cable tray:

1)应急照明和其他照明的电缆。

1) Emergency lighting and other lighting cables.

2)lkV以上和1kV以下的电缆。

2) Cables above 1kV and below 1kV.

3)同一路径向负荷供电的双路电源电缆。

3) A dual power cable that supplies power to the load along the same path.

4)强电和弱电电缆。如受条件限制需安装在同一层桥架上时，应用隔板隔开。

4) Strong and weak current cables. If it is required to be installed on the same level of bridge due to limitations, partitions should be used to separate it.

九、不锈钢桥架与各种管道平行或交叉时，其净距应符合表DQ4-1的规定。

9、 When stainless steel cable trays are parallel or cross with various pipelines, their clear distance should comply with the provisions of Table DQ4-1.

十、不锈钢桥架在穿过防火墙及防火楼板时，应采取防火隔离措施。

10、 When stainless steel cable trays pass through firewalls and fire-resistant floors, fire isolation measures should be taken.

十一、不锈钢桥架内的电缆应在首端、尾端、转弯及每隔50m处，没有编号、型号及起、止点等标记。

11、 The cables inside the stainless steel cable tray should be marked at the beginning, end, turns, and every 50m without numbers, models, and starting and ending points.

十二、不锈钢桥架内的电缆应在下列部位进行固定。垂直敷设时，电缆的上端及每隔1.50～2m处。水平敷设时，电缆的首、尾两端、转弯及每隔5～10m处。

12、 The cables inside the stainless steel cable tray should be fixed at the following locations. When laying vertically, the upper end of the cable and every 1.50-2m. When laying horizontally, the first and last ends of the cable, as well as at turns and every 5-10 meters.
