Based on analysis of known patent and scientific and technical information, new design of power line pylon has been developed, intended for installation in heaving permafrost soils. Cryophobic antifriction coating is applied to pylon surface located in active layer of soil to reduce intensity of pylon upfreezing from soil. It is proposed to place mechanical devices that increase adhesion to frozen soil below the zone of maximum summer thawing. The possibility of using polyurethane as cryophobic coating is considered. Studies have been carried out to maintain adhesion of coating to concrete surface in process of atmospheric exposure for two years.
