| （1）为了保证电缆汇线桥架安装方便，桥架与电缆之间必须满足以下数值： (1) in order to ensure the convenient installation of cable junction bridge, the following values must be met between bridge and cable: 在同一托臂上或同一平面上水平架设汇线桥架时，相邻汇线桥架之间的净距不应小于50mm When the cable tray is erected horizontally on the same support arm or on the same plane, the clear distance between adjacent cable trays shall not be less than 50mm. 两组汇线桥架平行架设时，之间净距不应小于600mm When two groups of cable trays are erected in parallel, the clear distance between them shall not be less than 600mm. （2）玻璃钢电缆桥架重叠架设时，层间垂直距离应满足下列数值： (2) when the FRP cable tray is overlapped, the vertical distance between layers shall meet the following values: 电力电缆为300mm。 Power cable is 300 mm. 控制电缆为2500mm。 The control cable is 2500mm. （3）为了电缆桥架安装的方便，其顶部到天花板，横梁及其他障碍物的底部最小垂直距离应满足下列数值。 (3) for the convenience of cable tray installation, the minimum vertical distance from the top to the ceiling, beam and other obstacles shall meet the following values. 电力电缆应不小于400mm。 The power cable shall not be less than 400mm. 控制电缆应不小于250mm Control cable shall not be less than 250mm |
