Abstract

Abstract: Expanded diameter conductor with less strand of inner layer is chosen as the research object in this paper. By utilizing static calculation software developed by China Electric Power Research Institute, the static stability analysis on expanded diameter conductor adopted in previous projects are performed. The purpose of the research is to investigate maximum diameter under the same diameter expand ratio or maximum diameter expand ratio under the same diameter. Taken the 25％ rated tensile strength as the critical tensile, the ladder diagram of static and economic of the expanded diameter conductor under different diameter expand ratio is achieved. According to analysis results, the expanded conductor adopted in previous projects meet safety requirement. The analysis results can be used in application of expanded diameter conductor in future.

Key words: transmission line, expanded diameter conductor with less strand in the layer, static stability calculation, seriation of the expanded diameter conductor, conductor selection
