现在电力工程在施工的时候，都会用到电缆桥架，这样是为了保护桥架质量，因此我们在安装的时候，需要掌握正确的安装方法，那么大家知道电缆桥架的安装方法是什么吗?对此了解多少呢?接下来我们一起来看看吧!
Now in the construction of electric power engineering, cable bridge will be used. This is to protect the quality of the bridge. Therefore, we need to master the correct installation method when we install it. Do you know what the installation method of cable bridge in Shandong Province is? How much do you know about it? Next, let's have a look!
在吊顶内设置时，槽盖开口面的垂直间隙应保持在80毫米，槽段的利用率不应超过50%。
When it is set in the ceiling, the vertical clearance of the groove cover opening surface should be kept at 80mm, and the utilization rate of the slot section should not exceed 50%.

2.桥架跨越电气设备时，桥架与电气设备的净距不得小于0.5毫米，两组平行铺设在同一高度时，净距不得小于0.6米
2. When the bridge spans the electrical equipment, the clear distance between the bridge and the electrical equipment shall not be less than 0.5mm. When two groups of parallel laying are laid at the same height, the clear distance shall not be less than 0.6m
3.在水平、垂直桥和垂直的山东电缆桥架中敷设电线时，应捆绑缆线：
3. When laying wires in horizontal, vertical bridges and vertical cable trays in Shandong, the cables shall be bound
根据缆线的类型、电缆直径和缆线线芯数，24对电缆进行捆扎，25对及以上的主干电缆、光缆和其他类型的电缆进行捆扎
According to the type of cable, cable diameter and number of cable cores, 24 pairs of cables are bundled, and 25 pairs of trunk cables, optical cables and other types of cables are bundled
(2)绑扎间距不应大于1.5米，扣间距应均匀，松紧适度。
(2) The binding spacing should not be greater than 1.5m, and the buckle spacing should be uniform and moderately tight.
4.桥架高出地面2.2米以上，桥架顶部至顶棚或其他障碍物的距离不应小于0.3米，桥架宽度不应小于0.1米，桥架内横断面填充率不应超过50%。
4. The bridge should be more than 2.2m above the ground, the distance from the top of the bridge to the ceiling or other obstacles should not be less than 0.3m, the width of the bridge should not be less than 0.1M, and the filling rate of the cross section in the bridge should not exceed 50%.
5.电缆引入点的位置和引入模式。一般来说，大量的电缆可以用垂直弯板和垂直引上引下，少量的电缆可以用导板或引管引下，并可以指示引下方式。
5. Location and mode of cable entry point. Generally speaking, a large number of cables can be led up and down with vertical bending plate and vertical lead, and a small number of cables can be led down with guide plate or lead pipe, and the way of leading down can be indicated.

6.山东电缆桥架上的缆线垂直敷设时，应每隔1.5米固定在缆线上端桥的支架上，水平敷设时，应每隔3-5米固定在缆线的头部、尾部和转弯处。
6. When the cable is laid vertically on the cable tray in Shandong, it should be fixed on the bracket of the end bridge of the cable at an interval of 1.5 meters; when it is horizontally laid, it should be fixed at the head, tail and corner of the cable every 3-5 meters.
7.在平行图上画出路线，并注明桥的起点、终点、转折点、分支点和吊点的坐标或定位尺寸和标高。如果能画出山东槽式桥架铺设的轴测图，材料统计会更准确。
7. Draw the route on the parallel diagram, and indicate the coordinates or positioning dimensions and elevation of the starting point, end point, turning point, branch point and lifting point of the bridge. If the axonometric drawing of Shandong trough type bridge can be drawn, the material statistics will be more accurate.
8.直线段：标明全长、桥层数、标高、型号和规格。转向点和分支点：标明所用转向盘的型号和规格。吊装剖面：标明标高变化，可以用局部详图或剖面图表示。
8. Straight line section: indicate the total length, number of bridge floors, elevation, model and specification. Steering point and branch point: indicate the type and specification of the steering wheel used. Hoisting section: Mark elevation change, which can be expressed by local detail drawing or section drawing.
9.桥架支撑点：如立柱、支架或非标支架、框架间距、安装方式、型号、规格、标高等，可在平面上列出，也可在不同的断面、单线图或详图中标注。
9. Bridge support points: such as column, support or non-standard support, frame spacing, installation mode, model, specification and elevation, which can be listed on the plane, or marked in different sections, single line drawings or detailed drawings.
10.铺设在线槽上的缆线不得捆绑，线槽内的缆线应顺直不得尽可能穿越。缆线不应溢出线槽，应绑扎固定在缆线进出线槽的转角处，垂直线槽缆线应每隔1.5米固定在缆线支架上。
10. The cables laid on the trunking shall not be bundled, and the cables in the trunking shall be straight and shall not cross as far as possible. The cables shall not overflow the trunking, and shall be bound and fixed at the corner of the cable going in and out of the trunking. The cables of the vertical trunking shall be fixed on the cable support every 1.5m.
山东电缆桥架是电气缆线集中管理的主要设备，除了正确安装桥架方法外，在出现灰尘或腐蚀性物质的地方，应尽量在桥架上加装盖板，这样可以更好地保护电气缆线。
Shandong cable bridge is the main equipment for centralized management of electrical cables. In addition to the correct installation method of cable tray, cover plate should be installed on the cable tray where dust or corrosive substances appear, so as to better protect the electrical cables.
