The electrical corrosion of the ADSS cable sheath under tension during operation is caused by the ground leakage current and dry strip arc of approximately 0. 5-5mA caused by the space potential (or electric field strength) coupled by capacitance. During operation, the ADSS optical cable, which is under tension, is in a strong electromagnetic field in the space around the conductor. Under the action of spatial. With the expansion of communication line coverage, the traditional inspection method for electrical corrosion defects in all dielectric self-supporting (ADSS) optical cables have faced issues of low efficiency and high costs.
