This paper proposes a new method for electrical corrosion assessment of ADSS optical cables based on leakage current characteristic analysis. Firstly, ADSS cable samples are subjected to salt spray treatment for varying durations, and the leakage current of each sample is. All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission. During operation, the ADSS optical cable, which is under tension, is in a strong electromagnetic field in the space around the conductor. The capacitive coupling between the optical cable and the conductor and the earth puts it in a position of spatial potential.
