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.

分类

classification

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材料，改善规划的，这种桥架运用起来本钱比较低，搬起来分量轻，造型比较特别，散热好且透气佳，一般用在直径比较大的电缆，较为合适高或是低压动力电缆。

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、托盘式电缆桥架

2. Tray type cable tray

优点是分量很轻，负分量很大，造型美观而且结构很简洁，装置也不大困难，一般用在石油，化工，轻工，电讯等，合适动力电缆的装置，也能够用于操控电缆。

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、槽式电缆桥架

3. Trough type cable tray

这是一种完全封闭的电缆桥架，合适有高灵敏体系的操控电缆，像是计算机电缆，通讯电缆等等，它能够很有用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，重 点是不需要维护，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。

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、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，它是归于一种新型的桥架，是电缆桥架中的二代新产品，运用于各项工程，各个单位，便利工程中的规划，也便利生产时的运送，是一个很优异的产品。

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.

装置要求

Device requirements

1、电缆桥架跟要用电的设备遇届时，距离要大于0.5公尺。

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

2、两组电缆在同一个高度平行时，距离要大于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 in the trunking shall be smooth and straight.

4、在吊顶里边设置的时候，槽盖开启的那一面要保持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 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，这样才能够高 效率又安 全的完结工程。

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.
