As we all know, the load of cable bridge is mainly divided into three aspects: load, dynamic load and additional load. Then, what are the specific differences and characteristics of these three types of load?

In fact, the static load refers to the types and numbers of cables laid in the cable tray, as well as the outer diameter weight / unit length of each cable. These basic parameters should be strictly counted according to the different routes of cable laying. Dynamic load refers to the weight of construction and maintenance personnel in the process of installation and maintenance of cable bridge. In fact, for light cable bridge, we generally do not consider dynamic load, that is, it is not allowed to stand on the bridge. If it is necessary to consider the situation of standing personnel, it is necessary to reduce the span properly. Finally, the additional load only refers to the load formed by ice and snow, wind and electromagnetic force outdoors. It is related to the natural meteorological conditions of the installation site and the nature of the electrified body. In the design, the corresponding calculation should also be based on their conditions.
