Loading and strength of overhead transmission lines
Applies to overhead lines of nominal voltage above 45 kV. It may
also be applied to lines with a lower nominal voltage.
The purpose of this report is to propose relationships between
loads imposed on transmission lines and the strengths of
transmission lines components in order to obtain safe and
economical designs.
Has the status of a technical report.
