Main factors of electric corrosion in ADSS optical cable line
The ADSS cable subjected to tension during operation is in the strong electromagnetic field existing in the space around the wire, and the capacitance coupling between the cable and the earth makes it in a space potential position. Under the action of space potential, the wet or dirty (inevitable) surface of the optical cable will produce a ground leakage current and heat, the heat will make the optical cable surface water evaporation, random (uncontrollable) to form a dry zone, blocking the surface leakage current. When the potential at both ends of the strip is high enough, a discharge is generated to form an arc (called a "dry strip arc"). The basic conditions for the occurrence of electrical corrosion are certain leakage current and high enough space potential.
