“Experts have conducted in-depth research on the oxidation mechanism of copper strips in medium voltage power cables, analyzed the influencing factors such as atmospheric environment and production process, and explored the oxidation situation of copper strips after contact with insulation shielding and cooling water impurities using the controlled variable method. The composition of the oxide on the inner side of the copper strip was compared and analyzed through infrared spectroscopy and X-ray photoelectron spectroscopy techniques. It was found that copper strips accelerate oxidation and discoloration in humid and acidic environments. Based on this, optimization strategies and preventive measures were proposed, providing new ideas for the study of copper strip oxidation resistance in power cables.”
