Static load is the type of cable, the number of roots, the weight of the outer diameter per root, and the unit length of the cable laid in the cable bridge. Dynamic load refers to the weight of construction maintenance personnel during the installation and maintenance of cable bridges.
For light cable bridge, generally do not consider dynamic load, that is, it is not allowed to stand on the bridge. If we need to consider the station, we should shorten the span. The additional load only in the outdoor is the load formed by ice, snow, wind and electromagnetic force. It is related to the natural weather conditions and the nature of the electrified body in the area of the installation, and the design should be calculated according to various conditions.
强腐蚀性环境应采用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。
Corrosion resistant flame retardant cable bridge with composite epoxy resin should be used in strong corrosive environment. 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.
The tray type, trough type, step type, glass anticorrosive flame retardant cable bridge or steel ordinary bridge can be selected according to the on-site 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.
(FB) type compound anticorrosive shielding cable bridge should be selected when the cable network is shielded from the electrical interference or the requirements of the protective external (e.g., corrosive liquid, flammable dust and other environment).
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。
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.
