电缆桥架分为槽式、托盘式、梯子式、网格局等结构，由支架、支撑臂和设备附件组成。应具有结构简单、外形美观、配置灵活、维修方便等特点。所有零件都需要镀锌，桥架安装在露天建筑物外。下面来讲讲电缆桥架类型和品种的选择吧。

Cable trays are divided into trough type, tray type, ladder type, grid office and other structures, which are composed of supports, support arms and equipment accessories. It shall have the characteristics of simple structure, beautiful appearance, flexible configuration, convenient maintenance, etc. All parts need to be galvanized, and the bridge is installed outside the open building. Let's talk about the selection of cable tray types and varieties.

1、当需要屏蔽电气干扰或需要保护外部的电缆网络时（如：腐蚀性液体、可燃性粉尘等）。

1. When it is necessary to shield electrical interference or protect the external cable network (such as corrosive liquid, combustible dust, etc.).

2、强腐蚀环境应使用（F）型复合环氧树脂防腐阻燃电缆桥架。支撑臂和支架也应采用相同的材??料制成，以提高桥梁及其附件的使用寿命。在简单的灰尘堆积等需要覆盖的环境或野外场所应加盖板。

2. Type (f) composite epoxy resin anti-corrosion and flame-retardant cable tray shall be used in strong corrosive environment. The same material shall be used for the support arm and support?? To improve the service life of the bridge and its accessories. Cover plates should be added in simple dust accumulation and other environments or outdoor places that need to be covered.

3、除以上条件外，可根据现场环境和技术要求选用托盘式、槽式、阶梯式、玻璃防腐阻燃电缆桥架或钢质普通型桥架。在简单的灰尘堆积等需要覆盖的环境或野外场所应加盖板。

3. In addition to the above conditions, tray type, trough type, ladder type, glass corrosion-resistant and flame-retardant cable tray or steel ordinary cable tray can be selected according to the site environment and technical requirements. Cover plates should be added in simple dust accumulation and other environments or outdoor places that need to be covered.

4、在公共通道或过马路段的田间，该段应在底部台阶底部加垫板或使用托盘。大跨度跨越公共通道时，可根据用户要求增加桥架承载能力或选用排架。

4. In the field of public passage or road crossing section, the base plate or pallet shall be added at the bottom of the bottom step of this section. When a large span crosses a public passage, the bearing capacity of the bridge can be increased or bent can be selected according to the user's requirements.

5、大跨度（>3m）宜采用复合桥（FB）。

5. Composite bridge (FB) should be used for large span (>3m).

6、现场应使用复合环氧树脂桥（F）。

6. Composite epoxy resin bridge (f) shall be used on site.

所有的机械设备使用后都要定期进行检查、保养，电缆桥架厂家就来谈谈如何对电缆桥架设备进行检修、保养。

All mechanical equipment should be inspected and maintained regularly after use. The cable tray manufacturer will talk about how to overhaul and maintain the cable tray equipment.

1、电缆桥架设备平衡气缸动作状况及其机油润滑系统油路,接头等测试检查.

1. Test and check the action condition of the balance cylinder of the cable tray equipment and the oil circuit and joint of the oil lubrication system

2、电缆桥架设备滑块与导轨之间的摩擦较为频繁，应做必要的调整较正，检查接头部位的润滑优质及管路等，保证良好的运转。

2. The friction between the sliding block of cable tray equipment and the guide rail is relatively frequent, so necessary adjustment and correction should be made, and the lubrication quality of the joint and the pipeline should be checked to ensure good operation.

3、定期为 济南电缆桥架齿轮部位润滑：齿轮传动箱及内部机件因为经常运转损坏的可能性比较大，出现松动的可能性更大。

3. Regularly lubricate the gear parts of Jinan cable tray: the gear transmission box and internal parts are more likely to be damaged due to frequent operation, and the possibility of looseness is greater.
