电缆桥架是用于保护电缆的常用工具和设备。在许多项目中,由于缺乏对使用规范和相关知识的理解,设备的效果往往会降低。那么,使用电缆桥架的预防措施是什么?下面跟电缆桥架厂家一起来了解一下吧!
Cable tray is a common tool and equipment used to protect cables. In many projects, due to the lack of understanding of the use of specifications and related knowledge, the effect of equipment is often reduced. So, what are the precautions for using cable tray? Now with the cable tray manufacturers to understand it!
1、XQJ型电缆桥架装置的较大荷载支撑间距应小于允许荷载和支撑跨度。
1. The larger load support spacing of XQJ cable tray device should be less than the allowable load and support span.
2、在选择桥架的宽度时,应预留一定的备用空间,以便将来添加电缆。
2. When selecting the width of the bridge, a certain amount of spare space should be reserved for adding cables in the future.
3、当电源电缆和控制电缆较少时,它们可以安装在同一个电缆桥架上,但是电源电缆和控制电缆应该分开,中间用隔板隔开。
3. When there are few power cables and control cables, they can be installed on the same cable tray, but the power cables and control cables should be separated and separated by partitions.
4、当电缆桥架水平放置时,桥架之间的连接头应尽可能设置在跨度的1/4左右。水平敷设的电缆每隔2米左右固定一次,垂直敷设的电缆每隔1.5米左右固定一次。
4. When the cable tray is placed horizontally, the connector between the trays should be set at about 1 / 4 of the span as far as possible. The cables laid horizontally are fixed every 2 meters or so, and the cables laid vertically are fixed every 1.5 meters or so.

5、电缆桥架装置应可靠接地。如果用桥架作为接地干线,每层桥架的两端用16mm2软铜线(并联)连接,与总接地干线连通,长距离电缆桥架每隔30-50米接地一次。
5. The cable tray device shall be reliably grounded. If the cable tray is used as the grounding main line, both ends of each layer of cable tray are connected with 16mm2 soft copper wire (in parallel) to connect with the main grounding main line, and the long-distance cable tray is grounded every 30-50m.
6、桥架装置除需要防护罩外,在室外安装时应安装在防护罩的顶部,以防日晒雨淋,对于需要焊接安装的,焊件周围的焊缝厚度不得小于母材的厚度,接头需要进行防腐处理。桥架断面电缆填充率:电力电缆不应超过40%;控制电缆不应大于50%,弱电线路可达60%。
6. In addition to the protective cover, the bridge device shall be installed on the top of the protective cover when it is installed outdoors to prevent the sun and rain. For the need of welding and installation, the thickness of the weld around the weldment shall not be less than the thickness of the base metal, and the joint shall be treated with anti-corrosion. Cable filling rate of bridge section: power cable shall not exceed 40%; The control cable should not be more than 50%, and the weak current line can reach 60%.
以上是电缆桥架在施工过程中需要采取的预防措施,此外,在选择电缆桥架的宽度时,应预留一定的备用空间,电缆桥架装置应可靠接地,电缆桥架装置在安装在室外时,除了保护罩外,还应在其顶层安装保护罩。
The above are the preventive measures to be taken in the construction process of cable tray. In addition, when selecting the width of cable tray, a certain spare space should be reserved. The cable tray device should be reliably grounded. When the cable tray device is installed outdoors, in addition to the protective cover, the protective cover should also be installed on the top layer.
