提起电缆桥架的安装，想必大部分电气人员都非常清楚了，但是如果说到电缆桥架的质量通病及防治措施，可能不少电气人员都是只知其一就不知其二的。我们都知道电缆桥架是一种新型的电缆敷设装置，随着高度发展的电气化与自动化，特别是配电力式由多级配电发展到集中配电，从而使电缆的数量急聚增加以及自动控制技术的迅速发展而出现的。之前的地沟直埋式和支架式敷设电缆已满足不了大企业，大工业的使用要求，而电缆桥架则以造价低，施工快，配线灵活，便于装卸更换，不受位置限制，造型美观等诸多特点受到施工部门和使用单位的欢迎，从而使它迅速取代了旧的焊接支架敷设电缆形式。

　　When it comes to the installation of cable trays, most electrical personnel are probably very familiar with it. However, when it comes to the common quality problems and prevention measures of cable trays, many electrical personnel may only know one thing and not know the other. We all know that cable tray is a new type of cable laying device. With the highly developed electrification and automation, especially the development of power distribution from multi-level distribution to centralized distribution, the number of cables has increased rapidly, and the rapid development of automatic control technology has emerged. The previous trench buried and bracket type cable laying methods can no longer meet the requirements of large enterprises and industries. Cable trays, on the other hand, are popular among construction departments and users due to their low cost, fast construction, flexible wiring, easy loading and unloading, no location restrictions, and beautiful appearance. As a result, they quickly replace the old welding bracket cable laying form.

　　在电气工程施工过程中都会存在安装母线、敷设电缆、电缆桥架以及其他等质量通病。电气工程施工过程是安装工程重要组成部分，针对电气工程施工的质量通病，一定要引起足够重视，采取有效控制措施进行控制。安装母线之前，需要进行母线矫正，桥架电缆需要根据不同环境选择不同的桥架手段，对于敷设电缆的方式不同，合理规划施工技术。下面本文就来探讨一下电缆桥架安装常见质量问题及防治措施。以供广大电气人员参考学习。

　　During the construction process of electrical engineering, there are common quality issues such as installing busbars, laying cables, cable trays, and others. The construction process of electrical engineering is an important component of installation engineering. In response to common quality problems in electrical engineering construction, sufficient attention must be paid and effective control measures must be taken to control them. Before installing the busbar, it is necessary to perform busbar correction, and different cable tray methods need to be selected according to different environments. For different cable laying methods, reasonable construction techniques should be planned. The following article will explore common quality issues and prevention measures in cable tray installation. For the reference and learning of electrical personnel.

　　根据建筑物结构的不同，采用合理的固定1、方法。砖墙上固定托臂，应润水宜用于硬性灰面捻注螺栓，或用干硬性细石混凝土捣注螺栓或支架，待有了一定强度后才能固定

　　According to the different structures of buildings, adopt reasonable fixing methods. Fixed support arms on brick walls should be moistened and used for twisting bolts on hard gray surfaces, or for pounding bolts or brackets with dry and hard fine aggregate concrete. They can only be fixed after a certain strength has been achieved

　　但固定吊、支架螺栓的数量，要与吊、支架固定孔的数量相同，全部安装使用，且应紧固有效。

　　But the number of fixed suspension and bracket bolts should be the same as the number of suspension and bracket fixing holes, all installed and used, and should be tightened effectively.

　　2、操作应认真，接头处应平齐，通过变形缝时，可采取断开的措施，断开距离以100mm左右为宜，用此种方法解决沉降变形对桥架的破坏。

　　10、桥架污染严重，出现锈蚀现象，安装应加强保护，锈蚀出现应进行处理，采取与桥架防腐相同材料油漆进行喷涂。

　　10. The bridge frame is severely polluted and corroded. Installation should be strengthened for protection. If corrosion occurs, it should be treated by spraying the same material as the bridge frame anti-corrosion paint.

　　11、跨接接地导线应符合规范要求或设计要求;但截面不得小于4mm2铜芯导线。电缆排列素乱有交叉;在安装前应绘制排列图，以保证不交叉，安装时应按顺序施放电缆，以保证电缆排列有序、整齐。
