Galloping on power lines is a difficult matter. In this paper a galloping has been reproduced in a wind tunnel on a section of an actual conductor with actual ice shape. Aerodynamics is first detailed. Then flutter type and Den Hartod type galloping has been obtained in the wind tunnel depending on changeable ratio vertical to torsional frequencies. [less ▲]
