Analysis of the mechanical properties and electrical conductivity of aluminum wire by the dissolution temperature

Abstract

Abstract. Aiming at the fact that relevant conductivity of corrosion resistant aluminum conductor already used in the transmission line currently is reduced when the corrosion resistance is increased, the approach of "conduction equilibrium of rare earth and corrosion resistant alloy" is proposed that cerium-rich rare earth is added to the aluminum wires already meeting the electric engineering aluminum standards and then corrosion resistant alloying elements are added before special process treatment so that equilibrium is realized while meeting the international standards for aluminum wires for electric engineering. Its mechanism is analyzed and studied preliminarily. Meanwhile, the conductivity and corrosion resistance of the draw-forming aluminum conductor are compared and the results show that this technology is an effective way to improve the corrosion resistance of aluminum conductor while maintaining good conductivity.
