Electromagnetic Field Analysis in 132kV Double-Circuit Transmission Lines with ACCC Conductors

This paper presents the analysis of the electromagnetic field of a high voltage overhead double circuit transmission line using ACCC type conductors. The distinctive feature of this new technology in conductors is that they are made with aluminum wires arranged in a trapezoidal shape, using a carbon fiber core embedded in a high-temperature thermosetting resin. These construction parameters allow to increase the transmission capacity compared to an ACSR type conductor, reduction of losses, increase the span between structures, and also reduce the sag caused by thermal effects. The simulation of electromagnetic fields is carried out using the two-dimensional finite element analysis software FEMM, analyzing a vertical double-circuit transmission line using insulator strings and rigid insulators under the conductor's thermal limit state and nominal voltage. The results obtained are evaluated based on Argentine environmental regulatory standards.
