Cable tray can be divided into trough type, tray type and ladder type, grid office, etc. it is composed of support, bracket and device accessories. What are the types of cable tray? What should the device pay attention to? Next, we will clarify the classification and device requirements of cable tray.

分類

classification

1、梯階式電纜橋架

1. Ladder type cable tray

梯級式電纜橋架是依照著國內及國外的相關材料，改善規劃的，這種橋架運用起來本錢比較低，搬起來分量輕，造型比較特別，散熱好且透氣佳，一般用在直徑比較大的電纜，較為合適高或是低壓動力電纜。

The stepped cable tray is improved and planned according to the relevant materials at home and abroad. This cable tray has low cost, light weight, special shape, good heat dissipation and good air permeability. It is generally used for cables with large diameter, which is more suitable for high or low pressure power cables.

2、托盤式電纜橋架

2. Tray type cable tray

優點是分量很輕，負分量很大，造型美觀而且結構很簡潔，裝置也不大困難，一般用在石油，化工，輕工，電訊等，合適動力電纜的裝置，也能夠用于操控電纜。

The utility model has the advantages that the weight is very light, the negative weight is very large, the shape is beautiful, the structure is very simple, and the device is not difficult. It is generally used in petroleum, chemical industry, light industry, telecommunications, etc. the device suitable for power cables can also be used to control cables.

3、槽式電纜橋架

3. Trough type cable tray

這是一種完全封閉的電纜橋架，合適有高靈敏體系的操控電纜，像是計算機電纜，通訊電纜等等，它能夠很有用的屏蔽操控電纜的干擾，與環境中的重腐蝕，有超 級好的保護作用。

This is a completely closed cable bridge, which is suitable for control cables with high sensitive system, such as computer cables, communication cables, etc. it can effectively shield the interference of control cables and heavy corrosion in the environment.

4、大跨距電纜橋架

4. Long span cable tray

運用壽命長，且裝置比較簡單，本錢比較低，切開簡單，重 點是不需要維護，運用起來特別的便利，它是由拉擠玻璃鋼型材組裝起來的，能夠用在電力電纜，操控電纜，照明電纜或是其他配件上。

It has long service life, simple device, low cost and simple cutting. The key point is that it does not need maintenance and is particularly convenient to use. It is assembled from pultruded FRP profiles and can be used in power cables, control cables, lighting cables or other accessories.

5、組合式電纜橋架

5. Combined cable tray

照著現場的裝置隨意轉向，能夠變寬，分引上，引下，在隨意的部位不必打孔，不必焊接就把可用管引出，它是歸于一種新型的橋架，是電纜橋架中的二代新產品，運用于各項工程，各個單位，便利工程中的規劃，也便利生產時的運送，是一個很優異的產品。

According to the device on the site, it can be widened, led up and down at random, and the available pipe can be led out without drilling or welding. It belongs to a new type of bridge. It is a second-generation new product in the cable bridge. It is applied to various projects and units to facilitate the planning in the project and the transportation during production. It is a very excellent product.

裝置要求

Device requirements

1、電纜橋架跟要用電的設備遇屆時，距離要大于0.5公尺。

1. The distance between the cable tray and the equipment to be powered shall be greater than 0.5m.

2、兩組電纜在同一個高度平行時，距離要大于0.6公尺。

2. When two groups of cables are parallel at the same height, the distance shall be greater than 0.6m.

3、布放在線槽的纜線時，線槽里邊的纜線要順直。

3. When laying the cables in the trunking, the cables in the trunking shall be smooth and straight.

4、在吊頂里邊設置的時候，槽蓋開啟的那一面要保持80毫米的垂直凈空，線槽截面的利用率要小于百分之五十。

4. When it is set inside the ceiling, the open side of the slot cover shall maintain a vertical clearance of 80mm, and the utilization rate of the trunking section shall be less than 50%.

以上概括是電纜橋架的分類跟裝置要求，裝置時千萬要注意，這樣才能夠高 效率又安 全的完結工程。

The above summary is the classification of cable tray and device requirements. Pay attention to the installation, so that the project can be completed efficiently and safely.
