Short summary
Historically, as far as wet-snow loads were concerned, overhead line design was often based on experience. This article proposes a practical method to estimate the 90% confidence intervals of characteristic wet-snow loads based on meteorological data recorded at weather stations. As there is only one value of the ice-class masses proposed by ISO 12494 in each confidence interval, characteristic loads can be easily expressed in terms of ISO ice classes.
