    2、Basicinformation

    （1）荷载计算：计算索桥干线断面上单位长度的索重。

    (1)Loadcalculation:calculatethecableweightperunitlengthonthemainsectionofthecablebridge.

    （2）确定方向：根据建筑平面布置图，结合空调管道、电气管道的设置，维修方便，电缆线路密度，确定电缆桥架的更佳线路。在室内，应尽量沿建筑物的墙、柱、梁、楼板搭设。如果可以利用综合管廊架设，应在管的一侧或上方平行架设，并考虑引下线和支线尽量避免交叉。如果没有其他管架可供借用，则需自行设置（支撑）柱。

    (2)Determinethedirection:accordingtothelayoutplanofthebuilding,combinedwiththesettingofairconditioningpipesandelectricalpipes,convenientmaintenance,cablelinedensity,determinethebestlineofcablebridge.Indoors,itshouldbebuiltalongthewall,column,beamandfloorofthebuildingasfaraspossible.Iftheutilitytunnelcanbeusedforerection,itshallbeerectedinparallelononesideorabovethepipe,andthedownleadandbranchlineshallbeconsideredtoavoidcrossingasmuchaspossible.Ifthereisnootherpipesupportavailableforborrowing,itisnecessarytoset(support)thecolumnbyitself.

    （3）确定桥梁宽度：根据铺设的电缆数量、电缆直径和电缆间距，确定电缆桥架的型号和规格、支臂长度、支柱长度和间距、桥架的宽度和层数。

    （4）绘制电缆桥架的平面图和剖面图，绘制空间图，列出部分零件的材料表。

    (4)Drawtheplanandsectionofthecabletray,drawthespacemap,andlistthematerialtableofsomeparts.

    （5）确定安装方式：根据场地的设置条件确定桥梁的固定方式，选择悬挂式、垂直式、侧墙式或混合式。通常，连接器和紧固件一起提供。另外，根据桥梁结构选择相应的盖板。

    三、当弱电电缆与其它低压电缆共用桥架时，应严格选用具有外屏蔽层的弱电系统的弱电电缆，避免相互干扰。
