热镀锌电缆桥架的支撑点，如立柱、托臂或非规范支、构架的距离、设备方法、类型规范、标高．可以在平面上列表说明，也可分段标出；电缆引下点位置及引下方法，大批电缆引下可用垂直弯接板和垂直引上架，少数电缆引下，可用导板或引管，注明引下方法即可。

The support points of hot-dip galvanized cable trays, such as columns, brackets or non-standard supports, the distance between frames, equipment methods, type specifications, and elevations, can be listed and explained on the plane or marked in sections; The location and method of cable routing points can be determined by using vertical bending plates and vertical routing brackets for a large number of cables, and by using guide plates or conduits for a small number of cables, indicating the routing method.

热镀锌电缆桥架要高出地面2.2米以上，桥架顶部距顶棚或其它障碍物不小于0.3米，桥架宽度不小于0.1米，桥架内横断面的填充率不逾越50％；电缆桥架内缆线垂直敷设时，在缆线的上端和每距离1.5米处，应固定在桥架的支架上，水平敷设时，在缆线的首、尾、转弯及每距离35米处进行固定；布放在线槽的缆线可以不绑扎，槽内缆线应顺直，尽量不穿插，缆线不该溢出线槽，在缆线进出线槽部位，转弯处应绑扎固定。垂直线槽布放揽线每距离1.5米处固定在缆线支架上；

The hot-dip galvanized cable tray should be at least 2.2 meters above the ground, with the top of the tray not less than 0.3 meters away from the ceiling or other obstacles. The width of the tray should not be less than 0.1 meters, and the filling rate of the cross-section inside the tray should not exceed 50%; When laying cables vertically in cable trays, they should be fixed on the brackets of the tray at the upper end and every 1.5 meters distance. When laying horizontally, they should be fixed at the beginning, end, turn, and every 3 to 5 meters distance; The cables laid in the cable trough can be left unbound. The cables inside the trough should be straight and not inserted as much as possible. The cables should not overflow the trough. They should be tied and fixed at the entrance and exit of the trough, as well as at the turning points. The vertical cable tray is used to lay cables and fix them on the cable bracket at a distance of 1.5 meters;

在吊顶内设置时，槽盖敞开面坚持80毫米的垂直净空，线槽截面利用率不逾越50％；拿了桥架在进行水平敷设时，支撑距离一般为1.5-3m，垂直敷设时，固定在建筑物构体上的距离不小于2m；

When setting up in the ceiling, the open surface of the trough cover should maintain a vertical clearance of 80 millimeters, and the utilization rate of the trough section should not exceed 50%; When laying the bridge horizontally, the support distance is generally 1.5-3m, and when laying vertically, the distance fixed to the building structure is not less than 2m;

在平行图上绘出热镀锌电缆桥架的路由，要注明桥架起点、完毕、拐弯点、分支点及升降点的坐标或定位尺度、标高，如能制作桥架敷设轴侧图，则对材料计算将更准；热镀锌电缆桥架与用电设备交越时，净距不小于0.5m；两组电缆桥架在同一高度平行敷设时，净距不小于0.6m；

Draw the route of hot-dip galvanized cable tray on a parallel diagram, indicating the coordinates or positioning scale and elevation of the starting point, completion point, turning point, branch point, and lifting point of the tray. If a cable tray laying axis side diagram can be made, the material calculation will be more accurate; When the hot-dip galvanized cable tray intersects with electrical equipment, the clear distance shall not be less than 0.5m; When two sets of cable trays are laid parallel at the same height, the clear distance should not be less than 0.6m;
