Cause Analysis to Corrosion Fracture of ADSS Optical Cable

For two 220 kV lines from corrosion cracking failure of ADSS cable, fiber optic cable with ADSSfailure state of the environment in which, using scanning electron microscopy - energy dispersive spectroscopy samples the corrosion morphology and composition analysis, found that the cablesurface corrosion pits, cracks empty and other defects, carbon, oxygen uneven distribution of the carbon mass fraction is significantly lower, to determine the package from the ADSS fiber optic cable for 2 corrosion cracking failure was mainly caused by the electrical corrosion.
