现在人们对于电缆桥架的安装越发重视，不过凡事都要讲究技巧，才能更好的使其发挥效果。下面济南电缆桥架厂家就电缆桥架安装工艺的注意事项为大家详细介绍一下。

Nowadays, people pay more and more attention to the installation of cable trays, but they must pay attention to skills in everything in order to better achieve its effectiveness. Below, Jinan cable tray manufacturer will provide a detailed introduction to the precautions for cable tray installation process.

1、螺母螺栓位置。

1. Nut bolt position.

安装时，电缆桥架连接板的螺栓螺母应位于桥架的外侧。当直线段钢制电缆桥架超过30m时，应有伸缩缝，其连接宜采用伸缩连接板;电缆桥架跨越建筑物伸缩缝处应设置伸缩缝。

During installation, the bolts and nuts of the cable tray connection plate should be located on the outer side of the tray. When the straight section steel cable tray exceeds 30m, there should be Expansion joint, and the expansion connection plate should be used for its connection; Expansion joint shall be set at the place where the cable tray crosses the Expansion joint of the building.

2、转弯半径。

2. Turning radius.

电缆桥架转弯处的转弯半径，不应小于该桥架上的电缆小允许弯曲半径的大者。这里，就要说一下电缆弯曲半径的问题了，在电缆施工过程中，为保证不损伤电缆和投运后的，特别规定了电缆的弯曲半径，电缆的小弯曲半径应符合相关规定的要求。

The turning radius at the turning point of the cable tray should not be less than the larger allowable bending radius of the cable on the tray. Here, we will talk about the issue of cable bending radius. During cable construction, in order to ensure no damage to the cable and safety after operation, the bending radius of the cable is specially specified. The small bending radius of the cable should meet the requirements of relevant regulations.

3、弯曲半径。

3. Bending radius.

电缆桥架在制作的过程中，应充分考虑到电缆的弯曲半径问题。为避免电缆发生故障时，危及人身，电缆桥架全长同电缆支架一样，也应有良好的接地。当电缆桥架全长较长时，应进行多点接地。还应注意一些细节，如：固定电缆桥架连接板的螺栓应由里向外穿，以免划伤电缆。

During the production process of cable trays, the bending radius of the cables should be fully considered. To avoid endangering personal safety in the event of cable failure, the entire length of the cable tray, like the cable support, should also have good grounding. When the total length of the cable tray is long, multi-point grounding should be carried out. Attention should also be paid to some details, such as the bolts that fix the cable tray connection plate should be threaded from the inside out to avoid scratching the cable.
