Low-wind-pressure overhead conductor is a new type conductor that can reduce wind drag coefficient. There is little research on static characteristics and dynamic response of such conductor caused by wind load. This paper carries out wind tunnel tests of low-wind-pressure overhead conductor and conventional steel reinforced aluminum conductor. Variation rules of drag coefficient are obtained. The difference of wind yaw angels and sag between low-wind-pressure overhead conductor and conventional steel reinforced aluminum conductor are obtained by “catenary equation”. Davenport power spectrum is used to generate the time history of fluctuating wind speed. Wind-induced dynamic response model of overhead conductor midpoint is established. Comparative analysis are carried out between the low-wind-pressure overhead conductor and conventional steel reinforced aluminum conductor on the time history of overhead conductor midpoint displacement, trajectory of displacement and the frequency characteristics. Results show that drag coefficient and wind yaw angels of low-wind-pressure overhead conductor are less than the conventional steel reinforced aluminum conductor with the same radius. The difference of maximum sag between low-wind-pressure overhead conductor and conventional steel reinforced aluminum conductor is associated with the wind attack angle. Trajectory of displacement and the frequency characteristics of low-wind-pressure overhead conductor and conventional steel reinforced aluminum conductor are similar when inspired by the same fluctuating wind in high wind-speed area, but the vibration amplitude of low-wind-pressure overhead conductor is smaller.
