Abstract

The results of researches on the causes of suspension wires destruction of power transmission lines by methods of structural-phase metallographic analysis are described in this paper.

It was found out that the cause of the destruction of the power line fastening brackets is not the parallelism of the axes of the threaded parts of the fastening bracket in most cases. This particularity does not allow the fastening to be securely fastened to the traverse, as a result, it leads to a weakening of the threaded connection and the occurrence of additional bending cyclic stresses, which cause fatigue failure.
