Factors that determine the carrying capacity of [ FRP cable duct ]

Carrying capacity is the quality requirement of the manufacturer, because all the advantages must be carried out under this premise. If there is no good carrying capacity, other advantages are not useful on paper. So, what are the determining factors?

The bearing capacity of FRP cable trough is determined by the load, which can be mainly divided into dynamic load, static load and additional load, which will be introduced in detail below:

1. Dynamic load refers to the weight of construction and maintenance personnel during the installation and maintenance of FRP cable grooves. For light cable bridges, dynamic load is generally not considered, that is, people are not allowed to stand on the bridge. If standing people need to be considered, the span should be appropriately reduced.

2. Static load refers to the type, number of cables, and the outer diameter weight / unit length of each cable laid in the cable tray, which are separately listed according to the different routes of cable laying.

3. The additional load refers to the load formed by ice, snow, wind, and electromagnetic force only outdoors. It is related to the natural meteorological conditions of the installation site and the nature of the charged body. It should be calculated according to various conditions in the design.

Therefore, to ensure the bearing capacity of the fiberglass cable trough, the material is very important, but also needs a good design and good materials, both sides cooperate at the same time to ensure the quality of the product.
