This paper presents the most important results of the COALPRET research project, whose dual aim has been to carry out a general study of the characteristics of electrical conductors with high temperature performance and low sag, and apply these studies to the specific case of Spain's Alcira-Gandia 132 kV overhead transmission line. The final goal of the project is the replacement, in the Alcira-Gandia line, of the current ACSR conductors by another type of conductor with low sag characteristics. With this replacement, the aim is to increase the ampacity rating of the aforementioned line by at least 70%, with the smallest increase in sag, as there are currently numerous spans where the distances of line to earth are very compromising.
