二、不锈钢桥架水平安装时,宜按荷载曲线选取合适跨距进行支撑,跨距一般为1.5~3m。垂直敷设时,其固定点间距不宜大于2m。

2、 When installing stainless steel cable trays horizontally, it is advisable to select appropriate spans for support according to the load curve, with spans generally ranging from 1.5 to 3 meters. When laying vertically, the spacing between fixed points should not exceed 2m.

三、在有腐蚀或特别潮湿的场所采用不锈钢桥架布线时,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。

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.
