Radial temperature distribution in ACSR conductors applying finite elements

One of the most interesting aspect in the thermal analysis of an ACSR (Alum inium Conductors Steel Reinforced) conductor is the knowledge of the temper ature distribution in its interior. These conductors have the problem of he terogeneous characteristics in their interior. This paper proposes a model, based on the finite-element technique, that co nsiders temperature distribution in the interior of the conductor. The mode l relates the current distribution through the layers with the transmission of beat between them and with the exterior, both in steady state and in tr ansient.
