Abstract

This article, based on linearized equation of movement, considers an aerodynamical stability of bundled phase of overhead lines, covered with ice in wind flow. The Hurwitz criterion is used for determining critical speed of wind flow, when appears loss of stability of bundled phase. It is analyzed relationship between critical speed and lines characteristics, wire tension and attenuation ratio. In the end of this article appropriate conclusions are made.
