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.

电缆桥架的分类：

Classification of cable tray:

1、梯阶式电缆桥架

1. Ladder type cable tray

梯级式电缆桥架是依照着国内及国外的相关资料，改善规划的，这种桥架运用起来本钱比较低，搬起来重量轻，造型比较特别，散热好且透气佳，通常用在直径比较大的电缆，较为适合高或是低压动力电缆。

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、托盘式电缆桥架

2. Tray type cable tray

长处是重量很轻，负重量很大，造型漂亮并且结构很简洁，装置也不大困难，通常用在石油，化工，轻工，电讯等，适合动力电缆的装置，也能够用于操控电缆。

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、槽式电缆桥架

3. Trough type cable tray

这是一种完全封闭的电缆桥架，更适合有高活络系统的操控电缆，像是计算机电缆，通信电缆等等，它能够很有效的屏蔽操控电缆的干扰，与环境中的重腐蚀，有超级好的保护效果。

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、大跨距电缆桥架

4. Long span cable tray

运用寿命长，且装置比较简单，本钱比较低，切开简单，是不需要维护，运用起来特别的便利，它是由拉挤玻璃钢型材组装起来的，能够用在电力电缆，操控电缆，照明电缆或是其他配件上。

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、组合式电缆桥架

5. Combined cable tray

照着现场的装置随意转向，能够变宽，分引上，引下，在随意的部位不必打孔，不必焊接就把可用管引出，它是属于一种新型的桥架，是电缆桥架中的第二代新产品，运用于各项工程，各个单位，便利工程中的规划，也便利生产时的运输，是一个很的产品。

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.

电缆桥架的装置要求：

Installation requirements of cable tray:

1、电缆桥架跟要用电的设备遇到时，间距要大于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、两组电缆在同一个高度平行时，间距要大于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、布放在线槽的缆线时，线槽里边的缆线要顺直。

3. When laying the cables in the trunking, the cables inside the trunking should be straight.

4、在吊顶里边设置的时候，槽盖敞开的那一面要坚持80毫米的垂直净空，线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%.

以上概括是电缆桥架的分类跟装置要求，装置时千万要注意，这样才能够迅速的完成工程。

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