Considered have been here two cases of influence exerted on the line insulation namely the influence of the switching overvoltages as well as of the operating voltage combined in both cases with wind action. The admissible yearly discharge number has been accepted here as an initial point for both cases. The presented methods make it possible to calculate the design values of the wind velocity necessary for the' calculation of the insulator string deflection angle as well as of the minimum air clearances between the deflected conductor and the tower structure. The paper contains some statistical data about wind velocities and an adaption example of the worked out methods to designing of a 750 kV transmission line in Poland.
