Radial temperature distribution in ACSR conductors applying finite elements

One of the most interesting aspects in the thermal analysis of an ACSR (aluminium conductors steel reinforced) conductor is the knowledge of the temperature distribution in its interior. These conductors have the problem of heterogeneous characteristics in their interior. This paper proposes a model, based on the finite-element technique, that considers temperature distribution in the interior of the conductor. The model relates the current distribution through the layers with the transmission of heat between them and with the exterior, both in steady state and in transient conditions
