The copper wire drawing is one of cold forming operations which basicly the copper is used as pure material for various diameters & sections in electrical conductors industry. By cooperation with S.M.C company for cables industry in Damascus – Syria, a research has been done during 2 years on rod breakdown heavy drawing machine -HENRICH - GERMANY- 2 lines- with max productivity 25 ton/24hr. 50 samples of copper wire breaks and deformations have been studied & analyzed, thus the defects are classified in main statistics diagrams in gold of give main instructions that contribute in raising the quality level of local copper wire manufacturing & giving a whole view about this industry.
