Shandong cable bridge is widely used in electrical equipment and power engineering. Cable tray is divided into trough type, tray type and ladder type. In social life, we often see that let's look at the metal wiring problem of cable bridge.

　　(1)電纜橋架金屬線槽布線適合在房間正常環境下干燥，不易被機械設備損壞，但不適合現場金屬線槽腐蝕嚴重。

　　(1) Cable tray metal trunking wiring is suitable for drying in normal room environment, not easy to be damaged by mechanical equipment, but not suitable for serious corrosion of metal trunking on site.

　　(2)同一控制電路的所有相線和中性線應敷設在同一電纜橋架的金屬線槽內。行相同的相對路徑可以被放置在同一金屬線槽,電纜在橋或總截面的電纜(包括外保護層)不超過20%的橋的橫截面,負載電流傳輸線不適合超過30?？刂?、信號或其相位相似的線路，電纜或電纜的截割量應超過橋梁橫截面的50%，電纜或電纜的根數下限。

　　(2) All phase and neutral wires of the same control circuit shall be laid in the metal trunking of the same cable tray. The same relative path can be placed in the same metal trunking, the cable cross-section of the bridge or the total section of the cable (including the outer protective layer) is not more than 20%, and the load current transmission line is not suitable for more than 30. For lines with similar control, signal or phase, the cutting amount of cables or cables shall exceed 50% of the bridge cross section, and the lower limit of the number of cables or cables.

　　(3)山東電纜橋架金屬槽垂直或傾斜安裝時，應采取有效措施防止電纜或電纜線路槽移動。

　　(3) Effective measures should be taken to prevent the cable or cable route from moving when the metal tray of Shandong cable tray is installed vertically or obliquely.

　　(4)對于電纜橋架線槽處發現的線路，可采用金屬軟管、硬塑料軟管、半硬塑料軟管、金屬軟管或電纜。電纜或發現部分的電纜不得損壞。

　　(4) For lines found in cable tray trunking, metal hose, hard plastic hose, semi hard plastic hose, metal hose or cable can be used. The cable or part of the cable found shall not be damaged.

　　(5)電纜橋渣應平整不變形，內腔應光滑、清潔無毛刺。

　　(5) The cable bridge slag shall be flat without deformation, and the inner cavity shall be smooth, clean without burr.

　　以上是山東電纜橋架布線標準的介紹，希望您能理解。通常有很多電纜時，我們使用電纜橋架。電纜橋架的主要設備沿橋頂布置。臥式臥式矯直設備沿墻、沿軸設備、沿地設備。

　　The above is the introduction of Shandong cable bridge cabling standards, I hope you can understand. We usually use cable bridge when there are many cables. The main equipment of cable tray is arranged along the top of the bridge. Horizontal Horizontal Straightening equipment along the wall, along the axis equipment, along the ground equipment.
