Wet snow occurs in any region of the world where snow falls at ambient temperatures of around 0ºC. Wet snow may be sticky and easily adhere to exposed objects, such as electric transmission lines. Significant loading on transmission lines may result from wet snow accumulation, especially on conductors and ground wires; therefore, transmission lines must be designed to withstand such loads. The objective is to prepare a state of the art report for designing transmission lines for wet snow accumulation and make recommendations to improve current industry standards.

Value to Electric Cooperatives

It has been identified that wet snow accumulation is not sufficiently addressed in the current transmission line design standards. As such, this project aims to identify the gaps that must be closed in order to improve the reliability of modern transmission networks.
