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

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資料，改善規劃的，這種橋架運用起來本錢比較低，搬起來重量輕，造型比較特別，散熱好且透氣佳，通常用在直徑比較大的電纜，較為適合高或是低壓動力電纜。

The ladder type cable tray is improved and planned according to the relevant data at home and abroad. This kind of cable tray has the advantages of low cost, light weight, special shape, good heat dissipation and good ventilation. It is usually used in larger diameter cables, and is more suitable for high or low pressure power cables.

2、托盤式電纜橋架

2. Tray type cable tray

長處是重量很輕，負重量很大，造型漂亮并且結構很簡潔，裝置也不大困難，通常用在石油，化工，輕工，電訊等，適合動力電纜的裝置，也能夠用于操控電纜。

The advantages are light weight, heavy load, beautiful shape, simple structure, and easy installation. It is usually used in petroleum, chemical, light industry, telecommunications, etc. it is suitable for power cable installation and can also be used to control cables.

3、槽式電纜橋架

3. Trough cable tray

這是一種完全封閉的電纜橋架，適合有高活絡系統的操控電纜，像是計算機電纜，通信電纜等等，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 級好的保護效果。

This is a completely enclosed cable tray, suitable for control cables with high flexibility system, such as computer cables, communication cables, etc. it can effectively shield the interference of control cables and heavy corrosion in the environment, with super good protection effect.

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 installation, low cost and easy cutting. The key point is that it does not need maintenance. It is very convenient to use. It is assembled by pultruded FRP profiles and can be used in power cables, control cables, lighting cables or other accessories.

裝置要求

Device requirements

1、電纜橋架跟要用電的設備遇到時，間距要大于0.5公尺。

1. When the cable tray meets the equipment that needs electricity, the distance between them should be more than 0.5m.

2、兩組電纜在同一個高度平行時，間距要大于0.6公尺。

2. When the two groups of cables are parallel at the same height, the distance between them should 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 should be straight.

4、在吊頂里邊設置的時候，槽蓋敞開的那一面要堅持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 setting in the ceiling, the open side of the slot cover should adhere to the vertical clearance of 80mm, and the utilization rate of the slot section should 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，這樣才能夠高能率又安 全的完成工程。

The above summary is the classification of cable tray and the requirements of the device, so we must pay attention to the device, so that we can complete the project with high energy rate and safety.
