Power line insulators are heated by the sun and cool down during the night. The heating and cooling characteristics depend on the insulator material. The wetting of polluted insulators depends on various factors, such as humidity, ambient temperature and the temperature of the insulator surface. In this paper this phenomenon is investigated in the laboratory and on site for insulators made of various materials.
