Selection of cable tray types and types

电缆桥架作为布线工程的一个配套项目,目前尚无专门的规范指导,个生产厂家的规格程式缺乏通用性,因此,设计选型过程应根据弱电各个系统缆显得类型、数量,合理选定适用的桥架。

Cable bridge as a supporting project of wiring engineering, there is no special norm guidance, the specifications of manufacturers lack of universality, therefore, the design and selection process should be based on the type and quantity of each system cable appears weak, reasonable selection of applicable bridge.

1、需屏蔽电气搅扰的电缆网路或有防护外部（如：有腐蚀液休，易燃粉尘等环境）影响的要求时，应选用（FB）类槽式复合型防腐屏蔽电缆桥架（带盖）

1. If the cable network needs to be shielded from electrical disturbance or the requirement of protecting the external environment (such as corrosive liquids, inflammable dust and so on), the (FB) groove type composite anticorrosive shielding cable bridge (with cover) should be selected.

2、强腐蚀性环境应选用（F）类复合环氧树脂防腐阻燃型电缆桥架。托臂、支架也要选用相同资料，提高桥架及附件的使用寿命，电缆桥架。在简单积灰和其它需隐瞒的环境或野外场所宜加盖板。

2, strong corrosive environment should be selected (F) composite epoxy resin fire retardant and flame retardant cable tray. The bracket and bracket should also use the same data to improve the service life of the bridge and accessories, and the cable bridge. It is advisable to add cover plates in simple dust deposits and other hidden environments or outdoor areas.

3、除上述情况外，可根据现场还环境及技能要求选用托盘式、槽式、梯级式、玻璃防腐阻燃电缆桥架或钢质普通型桥架。在简单积灰和其它需隐瞒的环境或野外场所宜加盖板。

3. In addition to the above, tray type, trough type, cascade type, glass anti-corrosion and flame-retardant cable bridge or ordinary steel bridge can be selected according to the site environment and technical requirements. It is advisable to add cover plates in simple dust deposits and other hidden environments or outdoor areas.

4、在公共通道或野外跨过道路段，底层梯级的底部宜加垫板或在该段使用托盘 。大跨距跨过公共通道时，可根据用户要求提高桥架的载荷才能或选用行架。

4. When crossing a road section in a public passage or field, the bottom of the bottom cascade should be padded or trays should be used in this section. When a large span crosses the public passage, the load of the bridge can be raised or the rack is selected according to the user's requirements.

5、大跨距（>3m）要选用复合型桥架（FB）。

5, large span (>3m) to choose a composite bridge (FB).

6、野外要选用复合环氧树指桥架（F）。

6, the compound epoxy tree refers to the bridge (F).
