This book provides a comprehensive review of options for improving overhead power line performance in winter conditions, considering mechanical and electrical aspects. It discusses strategies to protect lines from ice and snow damage, including predicted ice loads, icing physics, and anti-icing and de-icing methods. It also describes historical, operational, and potential AI/DI systems and their long-term performance.

This comprehensive book delves into a thorough examination of various strategies for enhancing the performance of overhead power lines during winter conditions, encompassing both mechanical and electrical aspects. Drawing from the wealth of experience within the CIGRE community, it reveals a multitude of approaches aimed at safeguarding overhead power lines from the detrimental effects of heavy ice and snow buildup or electrical issues such as insulator icing flashovers. The initial phase involves considering the predicted ice loads derived from readily available databases, which is then complemented by fundamental principles of icing physics that influence accretion rates and the shedding of ice on traditional metal and ceramic surfaces as well as novel treated surfaces. These ice physics concepts form the foundation for categorizing and evaluating methods to mitigate or prevent icing on conductors, ground wires, and insulators, thereby preventing flashover events.
Numerous utilities operating in cold climate regions have successfully developed and implemented methods and strategies to reduce ice loads through the application of anti-icing (AI) and/or de-icing (DI) techniques. Generally, AI methods are employed either prior to or early in the ice build-up phase, while DI methods are activated during and occasionally after the ice formation process. The book provides a detailed description and analysis of various historical, operational, and potential AI/DI systems within the context of ice physics. This comprehensive review encompasses AI coatings, encompassing concepts, relevant material properties, application methods, and comprehensive test methods for assessing their long-term performance.
