Abstract: The article presents the results of experimental simulations of icing process on aluminum-steel conductors of overhead power transmission lines. The research was carried out using an experimental installation based on the climate chamber of the laboratory for testing building structures and structures of the Donbass National Academy of Construction and Architecture. The paper also considers the issues of experimental studies of the drag coefficients of aluminum-steel conductors in the MAT-1 wind tunnel. The data obtained as a result of the experiment can be used to predict the process of ice formation, as well as compare it with research results for other types of conductors in order to choose a rational solution for use in icy areas. The results of the work are necessary for use in overhead line load calculations in order to ensure trouble-free operation of overhead lines. The study of patterns and characteristics of the ice loads on conductors of overhead power lines, as well as the aerodynamic characteristics of conductors, allows us to develop scientific and methodological foundations for ensuring structural stability under wind and ice-wind effects.

Keywords: overhead power transmission lines (OPTL), conductor, icing, aerodynamics, experimental research.
