电缆在电缆桥架上的层次安排 Hierarchical arrangement of cables on cable trays
电缆桥架层次排列应是弱电流控制电缆在最上层，接着一段控制电缆、低压动力电缆、高压动力电缆依次往下排列。（见下表）这种排列便于屏蔽干扰、电
力电缆冷却、便于施工。
各层电缆桥架层的距离为 : 控制电缆≥ 220mm；动力电缆≥ 300mm；机械化敷设电缆≥ 400mm
The cable trays should be arranged in the uppermost layer of the weak current control cable, and then a section of the control cable, the low-
voltage power cable, and the high-voltage power cable are arranged in sequence. (See table below) This arrangement facilitates shielding
interference, cooling of power cables, and ease of construction.The distance between the cable tray layers of each layer is: control cable
≥ 220mm; power cable ≥ 300mm; mechanized laying cable ≥ 400mm
