The Hokkaido-Honshu DC transmission line, the
first DC transmission line in Japan, has been
successfully operated for past 14 years since its
operation started in December,1979 with 125kV and
its operating voltage was increased to 250kV in
June,1980. 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.
