设计选择过电缆桥架程应该出现类型，根据弱所有系统电缆数量，选择合适的桥。确定方向根据建筑布局，结合空调管道和电缆安装、维修方便，以及密度电缆路由确定电缆桥架的最佳路由。
The design chosen cable tray Cheng should appear type, according to the number of weak all system cable, choose the suitable bridge. Determine the direction according to the layout of the building, combining air conditioning pipeline and cable has the advantages of convenient installation, repair, and the density of cable routing to determine the optimal routing of cable tray.
确定桥梁宽度根据敷设电缆，电缆和电缆间距来确定电缆类型、规格、臂长、支柱长度、间距、桥梁宽度和层。确定安装根据固定的地方设置条件确定桥的选择，悬挂，直立，侧墙或混合类型，连接器和紧固件供应匹配，此外，根据桥梁结构，选择相应的板。
Determine the bridge width according to the laying of cable, cable and cable spacing to determine the cable type, specification, arm length, strut length, spacing, bridge width and layer. Determine installation according to the setting condition of fixed place to determine the choice of bridge, suspension, upright, side wall or mixed type, a connector and a fastener supply matching, in addition, according to the bridge structure, select the appropriate cover.
绘制电缆桥架，配置文件，本地站点也应该画空间图，列出的材料。与电力电缆桥相结合，应该是电力电缆和电缆的闭式弱，中间与分区。
Drawing cable tray, configuration files, local site should also draw a spatial map, list of materials. Combined with the electric cable bridge, the power and the cable should be closed weak, intermediate and partition.
弱电力电缆和其他低压电缆托盘组合，应该严格执行选择的弱电系统的外屏蔽层弱电电缆，避免相互干扰。其他安装电缆桥架从外部到内部建筑、桥梁向外坡不得低于1/100。和电气设备电缆跨线桥的间距不小于0.5米。两组的并行电缆桥架在相同的高度，不小于0.6米的间距。
Weak power cable and other low voltage cable tray should be combined, the outer shield ELV cable strict implementation of weak current system choice, avoid mutual interference. Other installation of cable tray from external to internal construction, bridges outward slope shall not be less than 1/100. Electrical equipment and cable overpass spacing of not less than 0.5 metres. Two groups of parallel cable tray at the same height, spacing of not less than 0.6 metres.济南电缆桥架
桥的路线，并行图来表示起点，终点桥，转折点，分支点和吊点坐标或位置尺寸，高度，比如画桥铺设轴测图，材料会更准确的统计数据。
Bridge route, parallel graph to represent the starting point and end point bridge, turning point, bifurcation and hanging point coordinates or location size, height, such as drawing a bridge laying axonometric drawing, material will be more accurate statistical data.
