The application of High-Temperature Low Sag conductors is one of the possible methods for improving the existing transmission network nowadays. This is an important issue that must be considered, especially if the transmission grid requires prospective expansion of new electrical connections. The purpose of the study has been to evaluate conductors of conventional core designs like AS, ACSR and composite core designs like ACCC and ACCR on the basis of two main criteria: the technical aspect (mechanical and thermal limitations) and the economic advantage, and to establish which of these conductors would be acceptable for upgrading the existing network. The comparative estimation was based on an existing overhead line model of the Latvian power network. The results of the analysis are presented in this paper.
