在工程设计中，电缆桥架的布置应根据经济合理性、技术可行性、运行安全性等因素综合比较，以确定最佳方案，还要充分满足施工安装、维护检修及电缆敷设的要求。

In engineering design, the layout of the cable tray should be based on economic rationality and technical feasibility, safety factors such as comprehensive comparison, to determine the best solution, but also fully meet the construction installation, maintenance and the requirements of the cable laying.

山东电缆桥架

Shandong cable tray

电缆桥架、线槽及其支吊架使用在有腐蚀性环境中，应采用耐腐蚀的刚性材料制造．或采取防腐蚀处理，防腐蚀处理方式应满足工程。

Steam-water cable tray, trough and its use in corrosive environment, the corrosion resistance of the rigid materials should be adopted. Or take the anti-corrosion treatment, anti-corrosion treatment should satisfy engineering.

电缆桥架在有防火要求的区段内，可在电缆梯架，托盘内添加具有耐火或难燃性能的板，网等材料构成封闭或半封闭式结构，并采取在桥架及其支吊架表面涂刷防火涂层等措施。其整体耐火性能应满足国家有关规范或标准的要求。在工程防火要求较高的场所．不宜采用铝合金电缆桥架。

Fire protection requirement of the cable tray in the segment, can be in the cable ladder, adding refractory or tray flame retardant performance of the board, the material such as network forms a closed or semi-closed structure, and take in the steam-water bridge and its surface besmear to brush fire retardant coating. Its overall refractory performance should meet the requirements of relevant national norms or standards. Should not be demanding in the engineering in place. Use aluminum alloy cable tray.

1、桥架的宽度和高度就按下表选择，并应符合电缆真充率不超过有关标准规范的规定值，动力电缆可取40-50%，控制电缆可取50-70%，另外需予留10-25%的式程发展余量。

1, the width and height of the bridge is according to the following table to choose, and should be in conformity with the relevant standard specification of the cable is filling rate is less than the specified value, power cable may take 40-50%, control cable desirable 50-70%, in addition to stay 10-25% of the allowance type process development.

2、各种弯通及附件规格应符合工程布置条件并与桥架相配套。

2, elbow, links, and accessories specifications should comply with the engineering layout condition and matching with the bridge frame.

3、支、吊架规格的选择，应按山东电缆桥架

规格、层数、跨距等条件配置。并应满足荷载的要求。

3, bronchitis, selection of hanger specification, should according to specification, the layer number of cable bridge in shandong, span configuration. And should meet the requirements of the load.
