1、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。
1, between support: support spacing should be less than or equal to the allowable load and load curve of support span.
2、电缆固定：汇线扬中电缆桥架水平敷设时，扬中电缆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1.5米左右固定一下。
2, fixed cable: cable tray horizontal laying, connecting bridge between should be set in the span of 1/4. Cable horizontal direction every 2 meters fixed look, vertical to the cable every 1.5 meters fixed.
3、扬中电缆桥架宽度：选择扬中电缆桥架的宽度时，应留有一定的备用空位，以便为今后增添电缆用。
3, the bridge width: the width of cable tray, should have some spare space, in order to add cable.
4、隔开敷设：当电力电缆和控制电缆较少时，可以在同一扬中电缆桥架安装，但中间须用隔板将电力电缆和控制电缆隔开敷设。
4, from laying: when the power cable and control cable is small, can be installed on the same cable tray, but must use a power cable and control cable laying off.
5、桥架高度为50、100时每端各6只连接孔，高度为150、200时每端各12只连接孔。
5, bridge height is 50, 100 at each end of 6 connecting holes, height 150, 200 at each end of 12 connecting holes.
