6. Standard data for overhead lines

6.1 Geometric and mechanical characteristics

The electrical parameters of overhead lines are calculated using the geometric and mechanical characteristics of the power transmission structures (voltage level, silhouette of towers, type of conductors, insulation distance, distance between conductors, average height of conductors above ground, etc.).

Figure 1 and tables 1 and 2 show the characteristics that influence the design of the structures, and for which the electrical parameters are calculated. For further information, please refer to...
