The paper reviews some recent results of the authors' research group related to the modeling of the hysteretic behaviour of metallic stranded cables and applies them to the definition of a theoretical model for the self-damping of a widespread typology of overhead electrical line conductors, namely the ACSR conductors. Closed-form expressions of the dissipated power per unit of length of the conductor, previously derived by the authors, are cast in a new form that allows for a more effective comparison with available experimental data of the literature.

Abstract
The paper reviews some recent results of the authors' research group related to the modeling of the hysteretic behaviour of metallic stranded cables and applies them to the definition of a theoretical model for the self-damping of a widespread typology of overhead electrical line conductors, namely the ACSR conductors. Closed-form expressions of the dissipated power per unit of length of the conductor, previously derived by the authors, are cast in a new form that allows for a more effective comparison with available experimental data of the literature.File in questo prodotto:
