Changing Ice and Wet Snow Loads on Conductors of Overhead Lines (OHLs) in the Netherlands in relation to climate change

Ice loads in the Netherlands originate mainly from ice accretion due to freezing rain and wet snow accretion. Traditionally, in The Netherlands, an empirical formula based on occurrence of freezing rain was used to determine ice loads. After two significant ice events in the 1980’s, it was concluded that for the northeastern part of the Netherlands higher ice loads could be expected. Since then, two “ice zones”
