Cable tray can be divided into trough type, tray type and ladder type, network format and so on. It is composed of bracket, bracket and device accessories. What are the types of cable tray? What should be paid attention to in the device? The following is to clarify the classification and device requirements of cable tray.

電纜橋架的分類：

Classification of cable tray:

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(nèi)及國外的相關(guān)資料，改善規(guī)劃的，這種橋架運用起來本錢比較低，搬起來重量輕，造型比較非常，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 information at home and abroad. This kind of bridge has the advantages of low cost, light weight, special shape, good heat dissipation and good air permeability. It is usually used in cables with large diameter, which is more suitable for high or low voltage power cables.

2、托盤式電纜橋架

2. Tray type cable tray

長處是重量很輕，負(fù)重量很大，造型漂亮并且結(jié)構(gòu)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。

It has the advantages of light weight, heavy load, beautiful shape and simple structure. It is usually used in petroleum, chemical industry, light industry, telecommunication, etc., which is suitable for power cable and can also be used for controlling cable.

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，更適合有高活絡(luò)系統(tǒng)的操控電纜，像是計算機電纜，通信電纜等等，它能夠很有效的屏蔽操控電纜的干擾，與環(huán)境中的重腐蝕，有超級好的保護效果。

This is a completely enclosed cable tray, which is most suitable for the control cable with high active system, such as computer cable, communication cable, etc. it can effectively shield the interference of control cable and heavy corrosion in the environment, and has 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，是不需要維護，運用起來非常的便利，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。

The utility model has the advantages of long service life, simple device, low cost and simple cutting. The key point is that it does not need maintenance. It is specially convenient to use. It is assembled by 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(xiàn)場的裝置隨意轉(zhuǎn)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，它是屬于一種新型的橋架，是電纜橋架中的第二代新產(chǎn)品，運用于各項工程，各個單位，便利工程中的規(guī)劃，也便利生產(chǎn)時的運輸，是一個很的產(chǎn)品。

It is a new type of cable tray, which is the second generation of new products in cable tray. It is used in various projects and units to facilitate the planning of the project and the transportation during production. It is an excellent product.

電纜橋架的裝置要求：

Installation requirements of cable tray:

1、電纜橋架跟要用電的設(shè)備遇到時，間距要大于0.5公尺。

1. When the cable tray meets with the equipment to be powered, the distance shall be greater than 0.5 m.

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 two groups of cables are parallel at the same height, the spacing should be greater than 0.6 M.

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 inside the trunking should be straight.

4、在吊頂里邊設(shè)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 inside the ceiling, the vertical clearance of 80 mm should be maintained on the open side of the slot cover, and the utilization rate of the trunking 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，這樣才能夠迅速的完成工程。

The above summary is the cable tray classification and device requirements, installation must pay attention to, so as to quickly complete the project.
