Summary

Electricity utilities need to design overhead lines to withstand potential cascade failures of towers which could occur as a result of exceptional icing or rupture of conductors. Some utilities simply design the lines with section towers at frequent intervals and other utilities use special devices called 'load control devices' (LCD) the function of which is to limit the stresses applied to the towers in cases of exceptional longitudinal loads.
