FIRST EDITION : JUNE 2007 - REVISION : APRIL 2016-----------------------------------------------------------------------------------------This brochure identifies and describes the most essential elements of the sag-tension calculation process and the various mathematical and experimental methods used to predict sag and tension of catenaries over the whole range of conductor temperatures and ice and wind loads: the goal is not to develop a unique calculation method but to provide the engineers with a basic explanation of the sag-tension calculation methods that are in common use throughout the world and with a physical understanding of the processes and mathematical relationships that underlie these methods.
