Overhead Line Design Guidelines for Mitigation of Severe Wind Storm Damage

The TB provides a concise design guideline on how best to mitigate the potential damage from the various forms of severe high intensity wind in any new overhead line designs. It also raises design and asset management issues related to the potential longer term risks from increases in magnitude and frequency of these severe events, during the design service life of new and existing lines, if climate change modelling is even partially correct.
