电缆桥架能够对电缆线起到一个非常好的保护效果，是电缆安装所必不可少的工具，但是在进行安装的时候也要注意一些事项，才能够起到更好的保护效果，使电缆线正常工作，那么 山东电缆桥架内可以放多少电缆线呢？

Cable bridge can play a very good protective effect on cable and is an indispensable tool for cable installation. But when installing, we should also pay attention to some matters to achieve better protection effect and make the cable work normally. How many cable lines can be placed in Shandong cable bridge?

不同的电缆线能够放置的数量是有着很大的差别的，同时电缆桥架内可以放置多少电缆线是有着规定的，按照截面积的大小进行计算，如果是动力电缆，那么桥架内可以放置的容量为其截面积的20%，如果是控制电缆的话，那么桥架内可以放置电缆线的截面积为其50%。

The number of cables that can be placed in different cable trays is very different. At the same time, there are regulations on how many cables can be placed in the cable tray, which are calculated according to the size of the cross-sectional area. If it is a power cable, the capacity that can be placed in the tray is 20% of its cross-sectional area. If it is a control cable, the cross-sectional area that can be placed in the tray is 50%.

电缆桥架内可以放多少电缆线的依据，主要是电缆桥架的允许载荷，例如300*100电缆托盘，其支持点间距分别为2、2.5、3、4米时，其允许载荷分别为160、99、66、34Kg/m。

The basis for how many cables can be placed in the cable tray is mainly the allowable load of the cable tray. For example, the allowable load of the 300 * 100 cable tray is 160, 99, 66 and 34Kg/m when the spacing of its support points is 2, 2.5, 3 and 4 meters respectively.

此外桥架安装选择需屏蔽电气干扰的电缆回路，有腐蚀的场所、易燃粉尘场所，应选用无盖无孔封闭型托盘，当需要因地制宜的场所，宜选用组装式托盘或有孔托盘及梯架；在容易积灰和其它需遮盖的环境或户外场所，宜带有盖板。

In addition, the cable circuit that needs to be shielded from electrical interference shall be selected for bridge installation. In places with corrosion and flammable dust, the closed tray without cover and hole shall be selected. In places where local conditions are required, the assembled tray or perforated tray and ladder shall be selected; Cover plates should be provided in the environment or outdoor places that are easy to accumulate dust and need to be covered.

低压电力电缆与控制电缆共用同一托盘或梯架时，应选用中间有隔板的托盘或梯架；在托盘、梯架分支、引上、引下处应设适当的弯通；因受空间条件限制不便装设弯通或有特殊要求时，可选用软连接板，铰接板；伸缩缝应设置伸缩板；连接两段不同宽度或高度的托盘、梯架可配置变宽或变高板。但在施工中，支、吊架和桥架的选择应依设计或工程布置条件选择。

When low-voltage power cable and control cable share the same tray or ladder, the tray or ladder with partition in the middle shall be selected; Appropriate bends shall be set at the tray, ladder branch, lead up and lead down; If it is not convenient to install the elbow due to space conditions or there are special requirements, the flexible connecting plate and hinge plate can be selected; Expansion joints shall be provided with expansion plates; The pallets and ladders connecting two sections of different width or height can be configured with widening or heightening plates. However, during construction, the selection of supports, hangers and bridges shall be based on the design or engineering layout conditions.

所以大家在进行选择电缆桥架的时候，要注意桥架内所放置的线不能够超标，在规定的数量范围内放置才能够更好安全使用。有什么疑惑或者需求就来我们网站 //www.comprepyme.com咨询吧！
