電纜橋架能夠對電纜線起到一個非常好的保護效果，是電纜安裝所必不可少的工具，但是在進行安裝的時候也要注意一些事項，才能夠起到更好的保護效果，使電纜線正常工作，那么山東電纜橋架內可以放多少電纜線呢？

Cable bridge can play a very good protective effect on cable and is an indispensable tool for cable installation. But when installing, we should also pay attention to some matters to achieve better protection effect and make the cable work normally. How many cable lines can be placed in Shandong cable bridge?

不同的電纜線能夠放置的數量是有著很大的差別的，同時電纜橋架內可以放置多少電纜線是有著規定的，按照截面積的大小進行計算，如果是動力電纜，那么橋架內可以放置的容量為其截面積的20%，如果是控制電纜的話，那么橋架內可以放置電纜線的截面積為其50%。

The number of cables that can be placed in different cable trays is very different. At the same time, there are regulations on how many cables can be placed in the cable tray, which are calculated according to the size of the cross-sectional area. If it is a power cable, the capacity that can be placed in the tray is 20% of its cross-sectional area. If it is a control cable, the cross-sectional area that can be placed in the tray is 50%.

電纜橋架內可以放多少電纜線的依據，主要是電纜橋架的允許載荷，例如300*100電纜托盤，其支持點間距分別為2、2.5、3、4米時，其允許載荷分別為160、99、66、34Kg/m。

The basis for how many cables can be placed in the cable tray is mainly the allowable load of the cable tray. For example, the allowable load of the 300 * 100 cable tray is 160, 99, 66 and 34Kg/m when the spacing of its support points is 2, 2.5, 3 and 4 meters respectively.

此外橋架安裝選擇需屏蔽電氣干擾的電纜回路，有腐蝕的場所、易燃粉塵場所，應選用無蓋無孔封閉型托盤，當需要因地制宜的場所，宜選用組裝式托盤或有孔托盤及梯架；在容易積灰和其它需遮蓋的環境或戶外場所，宜帶有蓋板。

In addition, the cable circuit that needs to be shielded from electrical interference shall be selected for bridge installation. In places with corrosion and flammable dust, the closed tray without cover and hole shall be selected. In places where local conditions are required, the assembled tray or perforated tray and ladder shall be selected; Cover plates should be provided in the environment or outdoor places that are easy to accumulate dust and need to be covered.

低壓電力電纜與控制電纜共用同一托盤或梯架時，應選用中間有隔板的托盤或梯架；在托盤、梯架分支、引上、引下處應設適當的彎通；因受空間條件限制不便裝設彎通或有特殊要求時，可選用軟連接板，鉸接板；伸縮縫應設置伸縮板；連接兩段不同寬度或高度的托盤、梯架可配置變寬或變高板。但在施工中，支、吊架和橋架的選擇應依設計或工程布置條件選擇。

When low-voltage power cable and control cable share the same tray or ladder, the tray or ladder with partition in the middle shall be selected; Appropriate bends shall be set at the tray, ladder branch, lead up and lead down; If it is not convenient to install the elbow due to space conditions or there are special requirements, the flexible connecting plate and hinge plate can be selected; Expansion joints shall be provided with expansion plates; The pallets and ladders connecting two sections of different width or height can be configured with widening or heightening plates. However, during construction, the selection of supports, hangers and bridges shall be based on the design or engineering layout conditions.

所以大家在進行選擇電纜橋架的時候，要注意橋架內所放置的線不能夠超標，在規定的數量范圍內放置才能夠更好安全使用。有什么疑惑或者需求就來我們網站http://www.pembertonchristian.com咨詢吧！
