支撑间距：支撑间距应小于等于载荷曲线允许载荷和支撑跨距。

Support spacing: the support spacing should be less than equal to the load curve allowed load and support span.

桥架宽度：选择电缆桥架的宽度时，应留有一定的备用空位，以便为今后增添电缆线。

Bridge width: when selecting the width of the cable bridge, there should be a certain reserve vacancy to add cable for the future.

隔开放设：当电力电缆和控制电缆较少时，可以在同一电缆桥架安装，但中间须用隔板将电力电缆和控制电缆隔开放设。

Separate setting: when power cables and control cables are small, they can be installed on the same cable tray, but the power cables and control cables must be partitions in the middle.

电缆固定：汇线桥架水平放设时，桥架之间的连接应尽量设置在跨距1/4处。水平走向的电缆每隔2米左右固定一下，垂直走向的电缆每隔15米左右固定一下。

Cable fixed: when the level of the remittance bridge is set, the connection between the bridges should be set at the span of 1/4 as far as possible. The horizontal direction of the cable is fixed every 2 meters, the vertical direction of the cable every 15 meters fixed every 15 meters.
