  Case Study for Application of Composite Interphase Spacers

  in Transmission Structures, Utility Practice & Experience

  Galloping is large amplitude, low frequency, wind-induced oscillation of overhead lines, often from ice accretion on the conductor that modifies its normal cross-sectional shape such that it becomes aerodynamically unstable. Read More >
