一、在室內采用不銹鋼橋架布線時,其電纜不應有黃麻或其他易延燃材料外護層。

1、 When using stainless steel cable trays for indoor wiring, the cables should not have an outer protective layer of jute or other flammable materials.

二、不銹鋼橋架水平安裝時,宜按荷載曲線選取合適跨距進行支撐,跨距一般為1.5~3m。垂直敷設時,其固定點間距不宜大于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、在有腐蝕或特別潮濕的場所采用不銹鋼橋架布線時,應根據腐蝕介質的不同采取相應的防護措施,并宜選用塑料護套電纜。

3、 When using stainless steel cable trays for wiring in corrosive or particularly humid areas, corresponding protective measures should be taken according to the different corrosive media, and plastic sheathed cables should be selected.

四、幾組不銹鋼橋架在同一高度平行安裝時,各相鄰不銹鋼橋架間應考慮維護、檢修距離。

4、 When several sets of stainless steel cable trays are installed parallel at the same height, maintenance and repair distances should be considered between adjacent stainless steel cable trays.

五、在不銹鋼橋架上可以無間距敷設電纜,電纜在橋架內橫斷面的填充率:電力電纜不應大于40%;控制電纜不應大于50%。

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、不銹鋼橋架(托盤)水平安裝時的距地高度一般不宜低于2.50m,垂直安裝時距地1.80m以下部分應加金屬蓋板保護,但敷設在電氣專用房間(如配電室,電氣豎井、技術層等)內時除外。

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、不銹鋼橋架不宜安裝在腐蝕性氣體管道和熱力管道的上方及腐蝕性液體管道的下方,否則應采取防腐、隔熱措施。

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、下列不同電壓,不同用途的電纜,不宜敷設在同一層橋架上:

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

1)應急照明和其他照明的電纜。

1) Emergency lighting and other lighting cables.

2)lkV以上和1kV以下的電纜。

2) Cables above 1kV and below 1kV.

3)同一路徑向負荷供電的雙路電源電纜。

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

4)強電和弱電電纜。如受條件限制需安裝在同一層橋架上時,應用隔板隔開。

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、不銹鋼橋架與各種管道平行或交叉時,其凈距應符合表DQ4-1的規定。

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、不銹鋼橋架在穿過防火墻及防火樓板時,應采取防火隔離措施。

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

十一、不銹鋼橋架內的電纜應在首端、尾端、轉彎及每隔50m處,沒有編號、型號及起、止點等標記。

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、不銹鋼橋架內的電纜應在下列部位進行固定。垂直敷設時,電纜的上端及每隔1.50~2m處。水平敷設時,電纜的首、尾兩端、轉彎及每隔5~10m處。

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.
