1、支撐間距：支撐間距應(yīng)小于等于載荷曲線允許載荷和支撐跨距。

1, between support: support spacing should be less than or equal to the allowable load and load curve of support span.

2、電纜固定：匯線揚中電纜橋架水平敷設(shè)時，揚中電纜橋架之間的連接應(yīng)盡量設(shè)置在跨距1/4處。水平走向的電纜每隔2米左右固定一下，垂直走向的電纜每隔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、揚中電纜橋架寬度：選擇揚中電纜橋架的寬度時，應(yīng)留有一定的備用空位，以便為今后增添電纜用。

3, the bridge width: the width of cable tray, should have some spare space, in order to add cable.

4、隔開敷設(shè)：當電力電纜和控制電纜較少時，可以在同一揚中電纜橋架安裝，但中間須用隔板將電力電纜和控制電纜隔開敷設(shè)。

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、橋架高度為50、100時每端各6只連接孔，高度為150、200時每端各12只連接孔。

5, bridge height is 50, 100 at each end of 6 connecting holes, height 150, 200 at each end of 12 connecting holes.
