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 ladder type cable tray is improved and planned according to the relevant materials 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 generally used in cables with large diameter, and 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。

It has the advantages of light weight, large negative weight, beautiful appearance, simple structure, and easy installation. It is generally used in petroleum, chemical, light industry, telecommunications, etc. it can also be used to control power cables.

3、槽式电缆桥架

3. Trough cable tray

这是一种完全封闭的电缆桥架，更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 enclosed cable bridge, which is most suitable for control cables with high sensitivity system, such as computer cables, communication cables, etc. it can effectively shield the interference of control cables and heavy corrosion in the environment, and has super good protection.

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。

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.

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，也便利生产时的运送，是一个很优异的产品。

According to the on-site device, it can turn at will, widen, separate and lead up and down, and lead out the available pipes at random positions without drilling or welding. It belongs to a new type of bridge and is the second generation of new product in the cable bridge. It is used in various projects and units to facilitate the planning of projects and the transportation of production. It is a very excellent product.
