Research on Defect Detection Technology of Composite Insulator Sheath

The composite insulator sheath plays an important role in protecting the core rod and insulation. thickness of must meet corresponding standard requirements. During manufacturing process, decentration leads to uneven sheath, which is easy cause risk insulators premature failure during operation. phased array detection technology can accurately detect so that defects such as (decentration rod) be detected, at end also effectively detected. DR identify interface between mandrel but there a distortion due inappropriate transillumination parameters.
