Galloping electric lines

WebMar 15, 2024 · Galloping lines can create problems for utilities and their customers. Power lines can “gallop” when rain freezes and coats the lines. As rain freezes on the line, it forms a teardrop shape that encases the wires and acts like an aerodynamic airplane wing. When wind blows, wires can start to move up and down in an oscillating motion. WebPosted: 12.08.2024. When Ice storms coat power lines, high winds can lead to lines that bounce and buck around. While rare, this movement is known as "galloping lines". …
