熱鍍鋅電纜橋架的支撐點，如立柱、托臂或非規范支、構架的距離、設備方法、類型規范、標高．可以在平面上列表說明，也可分段標出；電纜引下點位置及引下方法，大批電纜引下可用垂直彎接板和垂直引上架，少數電纜引下，可用導板或引管，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.

熱鍍鋅電纜橋架要高出地面2.2米以上，橋架頂部距頂棚或其它障礙物不小于0.3米，橋架寬度不小于0.1米，橋架內橫斷面的填充率不逾越50％；電纜橋架內纜線垂直敷設時，在纜線的上端和每距離1.5米處，應固定在橋架的支架上，水平敷設時，在纜線的首、尾、轉彎及每距離35米處進行固定；布放在線槽的纜線可以不綁扎，槽內纜線應順直，盡量不穿插，纜線不該溢出線槽，在纜線進出線槽部位，轉彎處應綁扎固定。垂直線槽布放攬線每距離1.5米處固定在纜線支架上；

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;

在吊頂內設置時，槽蓋敞開面堅持80毫米的垂直凈空，線槽截面利用率不逾越50％；拿了橋架在進行水平敷設時，支撐距離一般為1.5-3m，垂直敷設時，固定在建筑物構體上的距離不小于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;

在平行圖上繪出熱鍍鋅電纜橋架的路由，要注明橋架起點、完畢、拐彎點、分支點及升降點的坐標或定位尺度、標高，如能制作橋架敷設軸側圖，則對材料計算將更準；熱鍍鋅電纜橋架與用電設備交越時，凈距不小于0.5m；兩組電纜橋架在同一高度平行敷設時，凈距不小于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;
