山東電纜橋架選擇安裝注意事項：

　　Shandong cable tray selection installation note:

　　1．電纜橋架的大載荷、支撐間距應小于允許載荷和支撐跨距。

　　The maximum load, 1 cable tray support spacing should be less than the allowable load and support span.

　　2．橋架的安裝應以規范為準，目前可參照《電纜橋架安裝圖集86SD169》進行。橋架在安裝過程中嚴禁載人，如現場情況確有必要時，必須有保障設施方可載人，本事項對于不合格或非的操作人員尤為重要。

　　2 bridge should be installed in the national standards, the reference to "86SD169" of cable tray installation atlas. Bridge in the installation process is strictly prohibited manned, such as the scene when necessary, must have the safety protection facilities shall be manned, this for the unqualified or non professional personnel is very important.

　　3．橋架的立柱、托臂等支架可與基礎預埋件焊接固定，也可采用膨脹螺栓固定，對于現場焊接處一定要做好防腐處理，通常由用戶現場涂刷防腐漆。

　　The column, the bracket can be fixed with 3 bridge welding based embedded parts, also can use expansion bolts, the welding place should be well treated, usually by the user site besmear brushs anticorrosive paint.

　　4．電纜橋架水平敷設時，橋架間的對接處距支承點的距離應在跨距的1／4以內，對于大跨距橋架好放在支承架上對接，在有彎通或三通的地方則需單獨增加支承點，垂直方向的托臂每隔1．5m設一固定點。

　　4 cable bridge horizontal laying, the distance of supporting points should be in 1 / 4 span bridge within the joint between the distance, it is better for large span bridge connection on the supporting frame, were individually increases the supporting point in a general or three place, perpendicular to the direction of the bracket is provided with a fixed interval of 1.5m.

　　5．橋架內的電纜應用電纜卡帶、或金屬電纜卡子進行分組固定。對于水平敷設的電纜通常每隔2m左右作一固定點；對于垂直敷設的電纜應每隔1—1．5m固定一次，在改變標高的端部也應予以固定。

　　Cable cable cassette, or metal cable clip 5 group fixed tray. For laying cable level usually every 2m around a fixed point; the cable lifting should be every 1 1.5m fixed time, in the end changes should also be fixed.

　　6．電纜橋架按電力施工規范要求應進行良好接地，對于鍍鋅電纜橋架無須有專門接地裝置，其本體即可作為接地干線；對于表面進行非金屬處理的橋架則必須有專門的接地裝置；橋架的接地線可用VV-16mm2電纜或等截面的銅編織線，該線通常由用戶自備，如由本廠供貨，則應在合同中注明，長距離的電纜橋架每隔30—50m接地一次。

　　6 cable tray should be a good grounding in electric power construction specifications, for galvanized cable tray without special grounding device, which can be used as a grounding line; for the surface of non metal bridge must have ground special equipment; bridge ground be used VV-16mm2 cable or section of the copper braided wire, the line is owned by the user, such as by the factory delivery, it should be noted in the contract, the long distance cable tray every 30 50m grounding once.
