Abstract

Severe corrosion damage to transmission line towers poses a significant threat to the safe and stable operation of power systems, making precise assessment and effective repair essential. Corrosion damage assessment techniques include visual inspection, electrochemical testing, and non-destructive testing, each based on different principles and offering distinct advantages in terms of detection accuracy and applicability. Repair techniques encompass anti-corrosion coatings, cathodic protection, and structural reinforcement, which should be applied flexibly according to the specific condition of the damage. Integrating these assessment and repair technologies into a comprehensive prevention and control plan can enhance the corrosion resistance of towers, ensure the reliability of power transmission, and is crucial for the safe and stable operation of the power grid and the sustainable development of the power industry.
