I don't know how much you know about cable tray. Cable tray is a kind of building material commonly used in the electrical industry. It can protect the cable from external factors and ensure the safety of our electricity use. It's an assistant to us and the cable line, so to speak. Cable tray is laid inside the cable, it can make the installation of electrical appliances to a beautiful standard requirements, and we only need to open the cover in the maintenance, very convenient. Now let's learn how to choose the material of cable tray in Jinan. Let's have a look.

1、济南电缆桥架是用好的钢板加工成形的全封闭高强度矩形钢管，外观用镀锌处理，大大提高了防腐蚀能力。桥梁内外应光滑平整，无棱角，不应有扭曲、翘曲等变形现象。

1. Jinan cable tray is a fully enclosed high strength rectangular steel pipe processed with good steel plate. The appearance is treated with zinc plating, which greatly improves the corrosion resistance. The inside and outside of the bridge should be smooth and flat without edges and corners, and there should be no distortion, warpage and other deformation phenomena.

2、分线盒和插座盒： 敷线平面中，用作导线的转弯、相接。交叉是包线的十字路口，可以进行不同管形的变换和一定范围的高度调整。

2. Junction box and socket box: in the wiring plane, it is used for turning and connecting wires. Intersection is the intersection of the envelope, which can be transformed into different pipe shapes and adjusted in a certain range of height.

双桥线路配电箱内设置隔离板，确保强电流和弱电流之间的隔离和屏蔽。当敷设平面上的强弱电传输非常复杂时，桥梁采用水平位置的加深接线盒在水平方向穿越桥梁，大大方便了各种线路的走向。

Isolation board is set in the distribution box of double bridge line to ensure the isolation and shielding between strong current and weak current. When the strong and weak current transmission on the laying plane is very complex, the bridge adopts the deepening of horizontal position, and the junction box crosses the bridge in the horizontal direction, which greatly facilitates the direction of various lines.

3、专用出线口:用于引出导线，如有必要可作为电源、电话、视频插孔或计算机终端的出口。距分线盒230mm设置一个出线口，出线口之间标准间距为600mm。假如为双桥架，两跨接相邻小组出线口距离为1400mm。

3. Special outlet: it is used to lead out wires, and can be used as the outlet of power supply, telephone, Video Jack or computer terminal if necessary. An outlet is set 230mm away from the junction box, and the standard spacing between outlets is 600mm. If it is a double bridge frame, the distance between two adjacent groups is 1400mm.

4、连接支承附件:直线连接使用连通器的圆管接头，接线盒的圆管连接使用变径接头，齿条和圆管的连接使用端子，支架和调整螺栓用于支架支承和高度调整，其调整螺栓的长度因施工条件而异，高度调整一般为30~50mm的s形深度专用接头用于纵横交叉或横梁通过，扁平曲线用于桥的拐角，纵向弯曲用于桥的上下连接口，其他桥专用粘接剂用于桥与桥、桥与布线盒的连接部。

4. Connecting supporting accessories: straight connection uses circular pipe connector of connector; round pipe connection of junction box uses reducing joint; connection of rack and pipe uses terminal; bracket and adjusting bolt are used for support and height adjustment. The length of adjusting bolt varies according to construction conditions. S-shaped depth special joint with height adjustment of 30 ~ 50mm is used for vertical and horizontal crossing or cross beam passing through The horizontal curve is used for the corner of the bridge, the longitudinal bending is used for the upper and lower joint of the bridge, and the special adhesive for other bridges is used for the connection between the bridge and the bridge, and between the bridge and the wiring box.
