AL-Tamimi and Wissam T. Alshammari AlHussein Engineering College, Iraq Abstract The conductivity of electrical wire depends on its main material. Silver, copper, gold and aluminium The aim of this paper is to evaluate the effect of are the most conductive metals. Copper ranks as the drawing process on the electrical and mechanical most widely used material for high tension wiring properties of copper wire. Electrical high tension systems [1]. network required cables to conduct electrical flow from one location to the next. The specific electrical Deformation in wire drawing is influenced by a and mechanical properties of the cable are affected number of factors; such as wire chemistry, approach by the forming that takes place during the drawing angle of drawing die, fabrication, drawing speed, and processes. The effects of cold drawing on electrical reduction are the most significant. The primary and mechanical properties of (99.9% Cu) c
