我们生活中很多地方都用电，所以电缆越来越多，电缆桥架也越来越多。据了解，在安装电缆桥架的过程中，经常会遇到一些场地需要加装盖板的情况，但具体情况如何呢？

Many places in our life use electricity, so there are more and more cables and more cable trays. It is understood that in the process of installing cable tray, we often encounter the situation that some sites need to install cover plates, but what is the specific situation?

如果电缆桥架安装在室外，则必须在顶层或每层安装保护罩。如果安装地点容易受到机械损坏或多尘环境，或有特殊要求的地方，必须安装防护罩电缆桥架安装在带孔的铁板或类似装置的下方，上面的桥架必须加装防护罩；如果上托盘的宽度小于下托盘的宽度，下托盘必须配备保护盖；当电缆桥架垂直安装时，必须在距地面两米范围内安装防护罩。

If the cable tray is installed outdoors, the protective cover must be installed on the top layer or each layer. If the installation site is vulnerable to mechanical damage or dusty environment, or where there are special requirements, a protective cover must be installed. The cable bridge must be installed under the iron plate with holes or similar devices, and the upper bridge must be equipped with a protective cover; If the width of the upper tray is less than that of the lower tray, the lower tray must be equipped with a protective cover; When the cable tray is installed vertically, the protective cover must be installed within two meters from the ground.

桥盖应在容易积尘的地方使用。用于敷设控制电缆和信号电缆的槽式桥架和无孔托盘桥架应加盖板，盖板可起到屏蔽作用。并且为了美观效果。电缆桥架罩是电缆桥架外侧的屏蔽罩，用于保护电力或其他通信电缆敷设人员。

The bridge cover should be used where dust is easy to accumulate. The tray tray and non perforated tray tray used for laying control cables and signal cables shall be provided with cover plates, which can play a shielding role. And for aesthetic effect. The cable tray cover is the shielding cover outside the cable tray, which is used to protect the laying personnel of power or other communication cables.

此外安装桥架注意事项也要了解到:

In addition, the precautions for installing the bridge should also be understood:

在桥架运输到施工现场的时候，就要提交产品的出厂合格证、省市级质监报告，还有技术鉴定文件等一些相关资料。

When the bridge is transported to the construction site, it is necessary to submit the factory certificate, provincial and municipal quality supervision report, technical appraisal documents and other relevant materials.

山东电缆桥架是一个无人员指导的布线工程，在产品的规格下，很多厂家的生产方式都是不同的，缺乏通用性是一个大劣势，在设计选型中，需要根据工程的要求，合理的选定所要使用的配件。

Shandong cable bridge is a wiring project without the guidance of professionals. Under the product specifications, the production methods of many manufacturers are different, and the lack of universality is a major disadvantage. In the design and selection, it is necessary to reasonably select the accessories to be used according to the requirements of the project.

在电缆桥架和电力电缆桥架合用时,需要把电力电缆和弱电电缆分开安装，中间还需要用隔板分隔。

When the cable tray and power cable tray are used together, the power cable and weak current cable need to be installed separately, and the middle needs to be separated by a partition.

在弱电电缆和低电压电缆合用的时候，应该做到选择那种有屏蔽功能的弱电电缆.

When the weak current cable and low voltage cable are used together, the weak current cable with shielding function should be selected

如果是由室外的电缆桥架进入建筑内是，它的坡度不能小于1/100，而与用电设备交越时，不能小于0.5m的净距。

If the outdoor cable tray enters the building, its slope shall not be less than 1 / 100, and when crossing with electrical equipment, it shall not be less than 0.5m clear distance.

需要在在平行图上画成桥架的起点、拐弯点、分支点、升降点以及终点。坐标的点位、尺寸都要进行精准的标识。画出桥架的敷设轴侧图,，可以使得材料的预算统计更加的精准。

The starting point, turning point, branch point, lifting point and end point of the bridge frame shall be drawn on the parallel diagram. Coordinate points and dimensions shall be accurately identified. Draw the laying shaft side diagram of the bridge, which can make the budget statistics of materials more accurate.
