Stainless steel cable tray is known as a weak current system of intelligent building. It usually has multiple information monitoring and communication facilities, which can be placed inside the building independently or attached to the electrical frame. There are three kinds of cable trays, namely trough cable tray, tray cable tray and cascade cable tray. Its selection shall be determined according to the type and quantity of cable display of each weak current system.

一、桥架宽度：根据布放电缆条数、电缆直径及电缆间距来确定电缆桥架的型号、规格,托臂长度,支柱长度、间距,桥架宽度和层数。

1、 Bridge width: determine the model and specification of cable bridge, bracket length, strut length, spacing, bridge width and layers according to the number of cables laid, cable diameter and cable spacing.

二、安装方式：根据场所的设置条件来确定合适的桥架安装方式,如悬吊式、直立式、侧壁式或是混合式,桥架连接件和紧固件一般是配套供应的,根据桥架结构选择相应的盖板。

2、 Installation method: determine the appropriate bridge installation method according to the setting conditions of the site, such as suspension type, vertical type, side wall type or hybrid type. The bridge connectors and fasteners are generally supplied together, and the corresponding cover plate is selected according to the bridge structure.

三、架设方向：根据建筑平面布置图,结合空调管线和电气管线等设置情况，以及电缆路由的疏密来确定电缆桥架的Z佳路由。在室内,尽可能沿建筑物的墙、柱、梁及楼板架设。

3、 Erection direction: determine the z-best route of cable tray according to the building layout plan, combined with the setting of air conditioning pipeline and electrical pipeline, as well as the density of cable route. Indoors, it shall be erected along the walls, columns, beams and floors of the building as far as possible.

四、施工图纸：应事先绘出电缆桥架平、剖面图,局部部位还应绘出空间图,开列材料表。

4、 Construction drawings: plan and section drawings of cable tray shall be drawn in advance, and space drawings and material lists shall be drawn for local parts.

五、荷载计算：事先计算电缆桥架主干线纵断面上单位长度的电缆重量。

5、 Load calculation: calculate the cable weight per unit length on the longitudinal section of the main line of the cable bridge in advance.
