ANTIICING COVER FOR POWERLINE Russian patent published in 2017 - IPC H01B13/16 H02G7/16 

FIELD: electricity.

SUBSTANCE: methods and systems for piezoelectric coating formation on the powerline cable with the use of the sol-gel materials. The cable may be supplied through the cavity with the sol-gel material, which contains the piezoelectric material, with getting the cable uncured overlayer. After that, one sets the layer solid using, for example, the infrared light, the ultra-violet light and/or other types of radiation. The cable may be hanged within the coating application system in such a way that the uncured layer does not contact any system components until the layer is appropriately cured. The cured layer piezoelectric parameters may be tested within the system in order to provide the reset control. The cured layer, which could be mentioned as the piezoelectric coating, provokes the resistance heating on the cable outer surface at the time of cable vibration because of the alternate current transfer and because of the environmental agents.

EFFECT: invention provides an opportunity to simplify the deicing on the lines.
