在电网应用中，电缆桥架发挥了什么作用与优势？电缆桥架也分为槽式，梯级式等，下面来讲讲 山东桥架的制造与安装留意事项。

What role and advantages does cable tray play in power grid application? The cable tray is also divided into trough type, ladder type, etc. Next, we will talk about the manufacturing and installation precautions of Shandong cable tray.

强、弱电线路应分槽敷设，强、弱电线路不得与线槽直接接触，强、弱电线路在分线盒（箱）交叉时须用金属隔板隔开。各种配线在地线槽内的只允许出口与分线盒连接。在施工和安装地沟管时，要求将所有地沟管连成一个可靠的整体。

Strong and weak current lines shall be laid in separate slots. Strong and weak current lines shall not directly contact the trunking. Strong and weak current lines must be separated by metal partitions when crossing junction boxes (boxes). The outlet of various wiring in the ground wire slot is only allowed to be connected with the junction box. During construction and installation of trench pipes, it is required to connect all trench pipes into a reliable whole.

采用弹线法确定桥架的安装位置，并对其进行定位，作好标记。竖井内桥架的安装基准线应先用悬吊法确定，随时观察预留孔，若不合适。应及时调整，并进行修补。

The installation position of the bridge shall be determined by snapping the line, and it shall be positioned and marked. The installation datum line of the cable tray in the shaft shall be determined by suspension method first, and the reserved holes shall be observed at any time, if not appropriate. It shall be adjusted and repaired in time.

按照施工图的桥架规范和设计标高对桥架进行定位，然后制作支架需要根据测量尺寸，支架按工厂化生产。无顶棚的吊顶，沿梁底吊装或靠墙支撑，有顶棚的，吊装或靠墙支撑。

The bridge shall be positioned according to the bridge specification and design elevation in the construction drawing, and then the support shall be manufactured according to the measured size and factory production. The suspended ceiling without ceiling shall be hoisted along the beam bottom or supported against the wall, and the suspended ceiling with ceiling shall be hoisted or supported against the wall.

考虑到建筑美观和便于维护，不挂顶的公共空间组合结构构件，可采用靠墙安装，屋内下弦支撑安装或柱子支撑安装。靠墙的支座采用膨胀螺栓固定，支座间间隔不超过2米。

Considering the beauty of the building and the convenience of maintenance, the composite structural members of the public space without ceiling can be installed against the wall, supported by the lower chord of the house or supported by the column. The supports against the wall shall be fixed with expansion bolts, and the spacing between supports shall not exceed 2m.

对于横跨建筑物变形缝、弯曲半径大于300mm的横截面积较大的横截面积段，应加装吊具，吊具安装时应保证桥架水平或垂直度符合要求。

For the section with large cross sectional area crossing the deformation joint of the building and the bending radius greater than 300 mm, slings shall be installed. During the installation of slings, the levelness or perpendicularity of the bridge shall meet the requirements.

桥架的接地处理，可采用连接板作为跨接线，将其连在一起。在连接板的两端安装镀锌弹簧垫圈，用不少于4mm2的软铜线跨越桥架，再将桥架与地线连接，形成电气通道。桥梁架体和地线主干至少应有两处连接。

For the grounding of the cable tray, the connecting plate can be used as the jumper to connect them together. Galvanized spring washers shall be installed at both ends of the connecting plate. Soft copper wires of not less than 4mm2 shall be used to cross the bridge, and then the bridge shall be connected with the ground wire to form an electrical channel. There shall be at least two connections between the bridge frame and the main grounding wire.
