母线槽的挠度应不大于跨度的多少
The installation of the bus groove can be directly received from the transformer to the low-voltage distribution cabinet, and also can be directly connected to the distribution system from the low-voltage cabinet as the main line of the distribution.
1、电缆桥架与一般工艺管道(如压缩空气管道等)平行架设时不小于400mm，与具有腐蚀性液体管道平行架设时不小于500mm，与热力管道平行架设，热力管道有保温层时不小于500mm，无保温层时不小于1000mm。
1, cable tray and general piping (such as compressed air pipe etc.) parallel erection shall not be less than 400mm, and the corrosive liquid pipeline parallel erection shall not be less than 500mm, set up in parallel with the heat pipe, heat pipe with insulation layer is not less than 500mm, no insulation layer is not less than 1000mm.
2、电缆桥架的总平面布置应作到距离短，经济合理，运行，并应满足施工安装，维修和敷设电缆的要求。
2, the overall layout of the cable bridge should be the shortest distance, economic, reasonable and safe operation, and should meet the requirements of construction, installation, maintenance and installation of cables.
3、电缆桥架从正常环境穿墙进入防火、防爆的环境时，墙上应安装相应的密封装置，从室内穿墙室外时，在墙的外侧应采取防雨措施。
3, the cable bridge from the normal environment through the fire, explosion-proof environment, the wall should be installed in the corresponding sealing device, from the interior through the wall to the outside, in the outer wall should be taken rainproof measures.
4、电缆敷设后，电缆桥架的挠度应不大于电缆桥架跨度的1/200。当电缆桥架的跨度≥6000mm时，其挠度应不大于电缆桥架的跨度的1/150。
4. After cable laying, the deflection of the cable tray shall be no more than 1/200 of the span of the cable bridge. When the cable bridge span is greater than or equal to 6000mm, the deflection should be less than 1/150 of the span of cable bridge.
5、电缆桥架与一般工艺管道交叉时，不小于300mm，与具有腐蚀性液体管道下方或具有腐蚀性气体管道上方交叉时，应不小于500mm，与热力管道交叉，热力管道有保温层时，应不小于500mm，无保温层时，应不小于1000mm。
