PREFABRICATED SUPPORT FOR POWER LINES AND METHOD OF ITS CONSTRUCTION Russian patent published in 2023 - IPC E04H12/00 H02G7/00 

FIELD: energy and construction.

SUBSTANCE: invention relates to the construction of wooden, lightweight steel, light alloy or composite prefabricated permanent or temporary power line supports, including in hard-to-reach areas, on soft soils, in simple and difficult weather conditions. A prefabricated support for a power line includes at least three bases that do not lie on the same straight line, including those connected by flexible or rigid connections, to which at least one pair of posts are hinged, equipped with telescopic links for adjusting the length, connected to each other above the level of the bases, although at least one horizontal beam and at least one strut, along the surface of which a winch included in the structure, due to the rope, can move the slide connected to the horizontal beam, realizing the self-lifting of the support from the ground to the design position only due to the interaction of its components without the use of external lifting and transport cars, tractors, aircraft, as well as lifting wires and lightning protection cables onto supports. A method for constructing such a support is also described.

EFFECT: possibility of erecting a power line support and installing traverses, insulating pendants, wires and lightning protection cables on it, including high voltage classes and large transitions, including on soft soils, particularly in difficult weather conditions, without drilling operations, without lifting and transport or traction machines external to the structure of the support (including helicopters and/or balloons) and without installing permanent and/or temporary anchors to secure the winch rope outside the support.
