不同规格的电线，在负荷方面会有差异。电线桥架则不说负荷，而是说荷载。那么，一般的电缆桥架荷载是多大呢？

Wires of different specifications will vary in load. Wire bridge does not say load, but load. Then, what is the general load of cable tray?

所谓电线桥架荷载，其实是让结构或构件产生内力和变形的外力及其它因素，或者是指施加在工程结构上使工程结构或构件造成效应的直接作用。通常，荷载还有属于自己的单位，是KN/㎡。

The so-called wire bridge load is actually the external force and other factors that make the structure or component produce internal force and deformation, or it refers to the direct effect exerted on the engineering structure to make the engineering structure or component produce effect. Generally, the load has its own unit, kn/ ㎡.

桥架荷载还分为静荷载、动荷载以及附加荷载。其中静荷载是指敷设在电缆桥架内的电缆种类、根数、每根的外径重量或是单位长度；动荷载则是电缆桥架安装和维护过程中施工维修人员的重量附加荷载所指代的范围比较窄，是指冰雪、风和电磁力所形成的荷载。

Bridge load is also divided into static load, dynamic load and additional load. The static load refers to the type, number, outer diameter weight or unit length of cables laid in the cable tray; Dynamic load refers to the weight of construction and maintenance personnel during the installation and maintenance of cable tray. The scope of additional load is relatively narrow, which refers to the load formed by ice and snow, wind and electromagnetic force.

后，桥架的荷载大小并不是固定的，而是需要根据桥架的类型、安装环境以及带电体的性质来决定的。所以，如果想要知道确切的电线桥架的荷载大小，可以通过这几个方面去分析。

After that, the load size of the bridge is not fixed, but needs to be determined according to the type of bridge, installation environment and the nature of electrified body. Therefore, if you want to know the exact load size of the wire bridge, you can analyze it from these aspects.

此外线缆桥架的安装是需要一定的空间的，因此，它对安装环境有很高的要求，需要空旷、开阔的环境，所以，平时我们在家里基本看不到，而在一些公共场所，如写字楼、酒店、广场等地能看到。

In addition, the installation of cable tray requires a certain space. Therefore, it has high requirements for the installation environment, which requires an open and open environment. Therefore, we can't see it at home at ordinary times, but in some public places, such as office buildings, hotels, squares and so on.

要知道 济南电缆桥架主要包括三个部分，分别是支架、安装零件以及托臂，另外，它还有不同的类型，主要按照结构的不同来作区分，具体包括槽式、托盘式和梯架式、网格式等结构。不同结构的桥架所适用的环境不同。

You should know that Jinan cable tray mainly includes three parts, namely, brackets, installation parts and brackets. In addition, it has different types, which are mainly distinguished according to different structures, including trough type, tray type, ladder type, grid format and other structures. Bridges with different structures are suitable for different environments.
