Methods and systems are proposed for forming piezoelectric coatings on power line cables using sol-gel materials. The cable can be fed through a container with a sol-gel material containing 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 the coating system in such a way that the uncured layer does not touch any components of the system until the layer is suitably cured. The piezoelectric characteristics of the cured layer can be tested in the system to provide closed-loop control. The cured layer, which may be referred to as a piezoelectric coating, causes resistive heating on the outer surface of the cable during cable vibration due to transmission of alternating currents and environmental factors. |
