The overhead transmission line of this DC line, which interconnects the Hokkaido and Mainland of Japan runs in the areas O.Skm to 12km apart from seacoast. Design ESDD values are 0.03~ 0.2Smg/cm'. Periodical inspection of every piece of insulator unit, periodical ESDD measurements, and investigation of insulator hardware corrosion have been conducted. According to the investigation results, the design ESDD values are adequate and zinc sleeve is effective against the electrolytic corrosion of pin. Any faulty insulator units have never been found.
