Electrical high tension network required cables to conduct electrical flow from one location to the next. The specific electrical and mechanical properties of copper conductor cable are affected by the forming that takes place during the drawing processes. The effects of cold drawing on electrical and mechanical properties of (99.9% Cu) copper conductor are examined as a function of drawing ratio.
Mechanical cold affected the electrical conductivity in copper wire. The investigation shows that the strength of copper wire is explained by the effect of work hardening due to the refining process of microstructure, also the surface temperature copper wire affected by the number of drawing passes.
Electrical and mechanical properties of copper conductor were investigated. The result shows that increases of wire surface temperature with numbered passes in linear relation. Linearity increases of ultimate tensile strength with reduction area up to (R_A= 22%). The electrical conductivity in copper wire increases up to (37%) IACS. Hardness through the C.S area varied according to the number of passes.
As for electrical and mechanical properties of copper conductor, copper is an excellent electrical conductor.
