To study the corrosion of old 220kV transmission lines especially conductor in Shanghai, methods as visual inspection andmetallographic analysis are used to conduct an experimental research on the atmospheric corrosion of old conductors. The appearances and metallographic structures of conductors in service are examined and their mechanical property indicators are analyzed.Based on the corrosion mechanism of aluminum and galvanized steel wires, the research on the corrosion of ACSR which has run for years concludes that the outer aluminum wires of the 220kV old conductors that have operated for years are more corroded than the inner wires and the resistivity exceeds the standards although there is no significant drop in the mechanical indicators. The results in this research can provide technical support and guidance for the life evaluation of old transmission lines in the country.
