作为布线工程的配套项目，电缆桥架目前还没有专门的安装方法的规范指导，各生产厂家的规格缺少通用化。
因此，苏鑫山东电缆桥架设计选型过程应根据弱电各个系统电缆的类型、数量，合理选定适用的桥架。
Therefore, the selection process of Su Xin Shandong Cable Bridge Design should be based on the type and number of weak current system cables, reasonable selection of suitable bridge.

要素1、定位方向：根据建筑平面布置图，结合空调管道安装、电气管道安装、维护方便、电缆路由的疏密来确定电缆桥架的佳路由。如果有可能的话，在室内安装墙壁、柱、梁和楼板，就应该尽可能地沿建筑物的墙壁、柱、梁和楼板平行安装，在使用综合管廊时，应考虑在管道的一侧或上方设置引下线和分支线，尽量避免交叉；如果没有其他管架，则需自设(支)柱。
Factor 1, Positioning Direction: According to the floor plan of the building, combined with the air conditioning pipe installation, electrical pipe installation, easy maintenance, cable routing density to determine the best route cable bridge. If possible, walls, columns, beams and floors should be installed indoors as much as possible in parallel to the walls, columns, beams and floors of the building, should consider the side of the pipeline or above the installation of lead and branch line, as far as possible to avoid cross; if there is no other pipe rack, you need to set (support) column.

要素2、荷载计算：在山东电缆桥架主干线中，单位长度电缆的重量计算。
Factor 2, load calculation: in Shandong Cable Bridge Trunk Line, the weight calculation of the cable per unit length.

要素3、桥架宽度的确定：根据铺设电缆的数量，电缆直径，电缆间距，电缆间距，桥架类型，规格，托臂长度，支柱长度，间距，桥架宽度和层数。
Factor 3. DETERMINATION OF BRIDGE WIDTH: Based on the number of cables laid, cable diameter, cable spacing, cable spacing, bridge type, specifications, arm length, pillar length, spacing, bridge width and number of layers.

要素4、安装方式：根据场地设置条件确定桥架的固定方式，可选用悬吊式、立式、侧壁式或混合式，连接件和紧固件一般配套，另外，根据桥架结构选用相应的盖板。
Element 4, installation: According to the site setting conditions to determine the fixed way of the bridge, can choose hanging type, vertical type, side wall type or mixed type, connectors and fasteners general matching, in addition, according to the bridge structure to choose the corresponding cover plate. Oh, Shit

要素5、绘制电缆桥架的平面、剖面图，局部部分还应绘制空间图，开列材料表。在使用 山东电缆桥架时，电力电缆与弱电电缆每侧应放置一面，中间用隔板分隔。弱电电缆与其他低电压电缆合用时，严格执行选用弱电电缆外屏蔽层的弱电电缆，以避免彼此间的干扰干涉。
Element 5, drawing the cable tray plane, section map, part of the space map should also be drawn, listing the material table. In the use of Shandong Cable Bridge, power cable and weak cable side should be placed on each side, separated by partitions. When weak cable is used with other low-voltage cables, the weak cable with the outer shield layer of the weak cable should be selected strictly to avoid interference between them.
