Retraining Air Lines 220kV Transmission in the Paraguayan Power System using High Temperature Conductors and Low Sag (HTLS) and their feasibility

In the present study was assessed the technical and economic feasibility to change in high voltage aerial transmission lines conventional ACSR conductors by High Temperature and Low Sag (HTLS) conductors of similar diameter and weight with the aim to increase the transmission capacity of these lines without the need to change the towers made of galvanized steel. It could be shown comparing the energy losses and the respective investment cost of 4 different types of HTLS conductors, that the GTACSR type conductors offer the highest economic advantage under the considered scenario.
