Abstract
Provided are methods and systems for forming piezoelectric coatings on power line cables using sol-gel materials. A cable may be fed through a container with a sol-gel material having a piezoelectric material to form an uncured layer on the surface of the cable. The layer is then cured using, for example, infrared, ultraviolet, and/or other types of radiation. The cable may be suspended in a coating system such that the uncured layer does not touch any components of the system until the layer is adequately cured. Piezoelectric characteristics of the cured layer may be tested in the system to provide a control feedback. The cured layer, which may be referred to as a piezoelectric coating, causes resistive heating at the outer surface of the cable during vibration of the cable due transmission of alternating currents and environmental factors.
