Shandong cable bridge is more and more widely used in power engineering or construction engineering, so installation is a problem that needs our attention. The stability of the bridge is also a problem that we need to pay attention to in installation. The quality of a bridge is related to many factors. Similarly, the stability of the bridge is also affected by many factors, Today, let's solve how to keep the cable tray stable.

1、山東橋架安裝前應注意定位放線，根據(jù)施工圖固定好位置，同時劃好水平垂直的線。接下來固定配件，轉備好螺絲和膨脹絲，固定橋架。之后就是調整橋架，使得橋架穩(wěn)定在設計好的位置上，固定完全。

1. Pay attention to positioning and setting out before installation of Shandong bridge, fix the position according to the construction drawing, and draw horizontal and vertical lines at the same time. Next, fix the accessories, prepare the screws and expansion wires, and fix the bridge. Then adjust the bridge to make it stable in the designed position and completely fixed.

2、在對橋架無源電纜線進行設計的時候，需要提供不同走向的布線，其中，弱電系統(tǒng)的各種纜線分類應該布放在橋架內，對于它較佳的路由選擇和安裝方式都是要依據(jù)走向的要求并且結合實際的建筑結構以及空調等等管線的位置來確定

2. When designing the passive cable of the bridge, it is necessary to provide wiring with different directions. Among them, various cable classifications of the weak current system should be arranged in the bridge. The better routing and installation methods should be determined according to the requirements of the direction and in combination with the actual building structure and the location of air conditioning and other pipelines

3、橋架之所以備受關注，主要是設計結構簡單，安裝門檻較低，同時橋架的維護性非常高，進行清潔和檢查比較方便，還可以應對多種復雜的嚴酷環(huán)境，所以在市場上廣受關注。在選擇橋架時應該選擇適合自己的橋架，同時注意安裝步驟。

3. The reason why the bridge has attracted much attention is that the design structure is simple, the installation threshold is low, the maintainability of the bridge is very high, it is convenient to clean and check, and it can also deal with a variety of complex and harsh environments, so it has attracted much attention in the market. When selecting the bridge, you should select the bridge suitable for yourself, and pay attention to the installation steps.

4、無源纜線不能與有源電纜并排鋪設，受條件所限，如果鋪放在同一橋架內，那么他的中間就須采用金屬隔板分設，這樣引出的纜線盡量避免平面交叉，橋架如果要穿越樓板或者伸縮縫的時候，應該在建筑圖上標出并留出相應的位置，避免在施工時臨時鉆空，因為這樣會破壞土建結構，在設計橋架中，為了防止電磁輻射的干擾，應考慮橋架的封閉性。

4. Passive cables cannot be laid side by side with active cables. Limited by conditions, if they are laid in the same bridge, metal partitions must be used in the middle, so that the outgoing cables can avoid plane crossing as far as possible. If the bridge wants to pass through the floor slab or expansion joint, it should be marked on the architectural drawing and leave corresponding positions to avoid temporary drilling during construction, Because this will damage the civil structure, in the design of the bridge, in order to prevent the interference of electromagnetic radiation, the sealing of the bridge should be considered.
