Abstract Icing of transmission line threatens the reliability of electric power system seriously. In recent years, although numerous anti-icing and de-icing methods were developed, this problem has not been totally solved in micro-meteorological and micro-topographic areas, due to the limitations of the proposed methods. Compared with aluminum conductor steel reinforced, the expanded diameter conductor, corresponds to a better anti-icing effect under the same transmission capacity. Therefore, this paper presented an anti-icing method by using expanded diameter conductor instead of bundle conductor. In this paper, the electrical factors were considered, the critical corona initiation voltage and surface electric field distribution characteristics of the expanded diameter conductor were analyzed. The results show that, the critical corona initiation voltage is lower than the operating voltage. The surface electric field of expanded diameter conductor is lower than that of the bundle conductor. Natural icing test results indicate that, the method of using expanded diameter conductor which has the same effective conductive area to replace bundle conductor can reduce the amount of icing quality by about 30%~80%. It can improve the anti-icing effect significantly, so as to achieve the purpose of anti-icing and mitigation without artificial intervention.

Key words： Expanded diameter conductor bundle conductor surface electric field collision rate ice quality natural icing
