【 摘 要 】

The paper presents the model of airflow around the conductor of overhead transmission line with the attached vibration damper of Stockbridge type. The analysis was performed for fixed Reynolds number Re = 12000, circular cross-sections of the conductor with the vibration damper. The purpose of the paper is to determine aerodynamic drag and lift coefficients and the frequencies for conductor and damper and also the pressure around them and in their wakes. Based on the analysis, the velocity distribution around the conductor and the damper was found. For analysis the model of RNG k - was used. On the basis of the performed study one can emphasize the need of control of interference of both conductor and attached dampers.
