Abstract

The technological development experienced by industrialized countries has brought about a huge increase of demand for electric power. As a result, the utilities in charge of electric power transmission and distribution have noticed that the high-voltage overhead lines are reaching critical values of ampacity and sag. In order to tackle this issue, we have undertaken the analysis of the eventual replacement of traditional aluminum conductor steel reinforced (ACSR) conductors with other conductors of better thermal properties. In the present paper, we report on the results obtained about how well the suspension strings of the ACSR conductors perform with the gap-type aluminum conductor steel reinforced (GTACSR) conductors. This study has been achieved using a multipurpose finite-element analysis (FEM) software package for both design and simulation.
