| Type of Structure | Description | Classification | Classification Description |
|---|---|---|---|
| About its function | The function of a structure in a transmission line is associated with the efforts to which each structure must be submitted. | Suspension | Structures subjected to efforts of vertical and horizontal transverse components |
| Anchoring | Structures subjected to vertical, horizontal transverse and longitudinal forces | ||
| About its resistance | How the structures transfer the sustained efforts to the materials and the region they were applied | Self-supporting | The fittings are capable to support all the efforts applied on the same |
| Cable-stayed | It uses cables to connect the structure and the soil | ||
| About its composition | There are many ways to transmit power using structures of several materials | Metal | Usually made of carbon steel, normal or high strength profiled or tubular |
| Concrete | Due to the material used, it must be made with the whole body, hindering its transport and assembly | ||
| Wood | Despite being made of easy extraction equipment and low cost, the wooden pole does not have great mechanical strength |
