Ice Accretion of Glaze Loads Model on Wires of Power Transmission lines

In connection with the process of glaze ice, prediction models about height and thickness of ice coating under uniform and non-uniform ice accretion of wire are presented by taking into account local collision efficiency, freeze coefficient and collection coefficient based on the existing model at home and abroad. The time-dependent ice models on the conditions of different median volume diameter of super-cooled droplets, wind speed and wire diameter are analyzed. Compared with the existing model, the proposed ice accretion model performed well in predicting ice's weight and thickness. At the same time, it can give some lights on ice disaster and anti-icing design for power transmission lines.
