Typhoon is one of the severest meteorological conditions for insulation of the surface of insulators on Okinawa Island. Insulator contamination has been measured for the last twenty years at ninety-one locations in the Island where pilot insulators were set up. The maximum contamination of ninety sites among ninety-one locations was due to typhoon's assaults. Twenty-five sites were subjected to special contamination area, where the contaminations of the insulators were over 0.35mg/cm^2 and forty-nine sites to very serious contamination area, where the contaminations of 0.12mg/cm^2 to 0.35mg/cm^2 were recorded., 紀要論文}, pages = {25--32}, title = {沖縄本島におけるがいしの汚損と地形による遮蔽効果} }
