电缆桥架由支架、支撑臂和安装附件组成，具有结构简单、外形美观、配置灵活、维护方便的特点。电缆桥架要根据环境选择如何安装，针对这一内容我们来讲解。

The cable tray is composed of bracket, support arm and installation accessories, which has the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. How to install the cable tray should be selected according to the environment. We will explain this content.

在工程设计中，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桥梁的布局。确定一个完全满足施工、安装、维护和电缆敷设要求的良好方案。

In the engineering design, the layout of bridges should be comprehensively compared according to factors such as economic rationality, technical feasibility and operation safety. Determine a good scheme that fully meets the requirements of construction, installation, maintenance and cable laying.

桥梁水平敷设时，其离地高度一般不小于2.5m。垂直敷设时，离地1.8m以下的部分应采用金属罩保护，但敷设在专用电气室除外。桥梁应水平敷设在设备夹层中，或小于2.5m，并采取保护接地措施。

When the bridge is laid horizontally, its height from the ground is generally not less than 2.5m. When laying vertically, the part below 1.8m above the ground shall be protected by metal cover, except for laying in special electrical room. The bridge shall be horizontally laid in the equipment interlayer, or less than 2.5m, and protective grounding measures shall be taken.

在腐蚀环境中使用时，桥架、线槽、支吊架应采用耐腐蚀的刚性材料。或采用防腐处理，防腐处理方式应符合工程、环境和耐久性要求。对于耐腐蚀或清洁度要求较高的场所，应选用铝合金电缆桥架。

When used in corrosive environment, the bridge, trunking, support and hanger shall be made of corrosion-resistant rigid materials. Or adopt anti-corrosion treatment, and the anti-corrosion treatment method shall meet the requirements of engineering, environment and durability. For places with high corrosion resistance or cleanliness requirements, aluminum alloy cable tray shall be selected.

在有防火要求的地区，山东电缆桥架、电缆槽可采用耐火或阻燃板、网等材料制成封闭或半封闭结构。桥梁及其支吊架表面喷涂防火涂料等措施。其整体耐火性能应符合有关规范或标准的要求。铝合金电缆桥架不宜用于防火要求高的场所。

In areas with fire prevention requirements, cable trays and cable trays in Shandong can be made of fire-resistant or flame-retardant plates, nets and other materials into closed or semi closed structures. The surface of the bridge and its supports and hangers shall be sprayed with fireproof paint and other measures. Its overall fire resistance shall meet the requirements of relevant national codes or standards. Aluminum alloy cable tray should not be used in places with high fire protection requirements.

需要屏蔽电磁干扰的电缆，或有外部阴影的环境要求，如室外阳光、油污、腐蚀性液体、易燃粉尘等。应选择无孔桥架电缆桥架。

Cables that need to be shielded from electromagnetic interference or environmental requirements with external shadows, such as outdoor sunlight, oil stain, corrosive liquid, flammable dust, etc. Cable trays without holes shall be selected.

山东电缆桥架厂家提醒大家，在容易积尘的地方，电缆桥架应使用盖板；在公共通道或室外路口，建议在底桥上加底板或使用无孔托盘。

Shandong cable tray manufacturer reminds you that cover plates should be used for cable trays where dust is easy to accumulate; In public passageways or outdoor intersections, it is recommended to add a base plate on the bottom bridge or use a perforated tray.

电缆桥架要根据环境选择如何安装的相关内容就讲解到这里了，当然安装时要使用正确的方法才行，这样才不会出现问题影响施工。更多内容就来网站 www.comprepyme.com关注吧！
