Selection of type and variety of cable bridge
1、需屏蔽电器干扰的电缆网路或有防护外部（如：有腐蚀液体，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. When the cable network that needs to be shielded from electrical interference or the requirements of the protective external (e.g., corrosive liquid, flammable dust, etc.), a (FB) type of compound type anticorrosive shielding cable bridge (belt cover) should be selected.
2、强腐蚀性环境应采用（F）类复合环氧树脂防腐阻燃型电缆桥架。托臂、支架也要选用同样材料，提高桥架及附件的使用寿命，电缆桥架。在容易积灰和其它需遮盖的环境或户外场所宜加盖板。
2, strong corrosive environment should adopt (F) composite epoxy resin fire retardant and flame retardant cable tray. The bracket and bracket should also use the same material to improve the service life of the bridge and accessories, and the cable bridge. It is advisable to add cover plates to the environment or outdoor areas where ash is easily accumulated and other need to be covered.
3、除上述情况外，可根据现场还环境及技术要求选用托盘式、槽式、梯级式、玻璃防腐阻燃电缆桥架或钢质普通型桥架。在容易积灰和其它需遮盖的环境或户外场所宜加盖板。
3. In addition to the above conditions, the tray type, trough type, ladder type, glass anticorrosion and flame retardant cable bridge or steel common type bridge can be selected according to the environment and technical requirements. It is advisable to add cover plates to the environment or outdoor areas where ash is easily accumulated and other need to be covered.
4、在公共通道或户外跨越道路段，底层梯级的底部宜加垫板或在该段使用托盘 。大跨距跨越公共通道时，可根据用户要求提高桥架的载荷能力或选用行架。
4. In the public passage or outdoor crossing the road segment, the bottom of the bottom ladder should be added with a pad or used in the section. When the large span crosses the public passage, the load capacity of the bridge can be raised according to the user requirements or the traveling frame can be selected.
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、户外要选用复合环氧树脂桥架（F）。
6, outdoor composite epoxy resin bridge (F).
