ANTI-ICING COATING FOR POWER TRANSMISSION LINES

摘要

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.

1. A method for forming a piezoelectric coating on a power line cable, the method comprising:
feeding the power line cable through a sol-gel material comprising a piezoelectric material,
wherein the feeding forms an uncured layer of the sol-gel material at least on an outer surface of the power line cable; and curing the uncured layer of the sol-gel material,
wherein the curing forms the piezoelectric coating on the power line cable,the piezoelectric coating comprising the piezoelectric material.
