TOWER BODY OF OVERHEAD TRANSMISSION LINE Russian patent published in 2013 - IPC E04H12/08 

FIELD: electricity.

SUBSTANCE: tower body of overhead transmission line contains a pyramid-shaped body consisting of two segments; each of segments is flexed from steel sheet thus forming half of pyramid lateral surface which two opposite edges are formed by two pairs of opposite outermost areas located at the tower foundation; at least two units spaced at the tower body length in order to fix the body at the pile and two compensating tubes. Body segments are interconnected rigidly at areas from the top up to the closest unit for body fixing at pile; at that pairs of the outermost body segments are interspaced at least at areas where units are located for tower fixing at the pile and between such areas. Each of tower body fixing units at cylindrical surface of the pile is equipped with two segments of rings connected rigidly and transversely at the same level with coupling at areas of outer circuit with inner opposite surfaces of the body segments and having inner ring-shaped parts for the purpose of coupling with lateral surface of the pile; two strainer units located at le level of ring segments at opposite sides of the body, at that each segment is made as a least one pair of thrusts rigidly connected at adjacent outermost segments of the body which can be contracted by threaded components. Each compensating tube has multi-faced cross-section in the form of two opposite parallel faces coupled by areas with at least two faces; at that compensating tubes are located at opposite sides of the body with couplings located at ends opposite to parallel faces with thrust units.

EFFECT: widening inventory of tower bodies for overhead transmission lines, increasing efficiency of resistance to loads occurring during their operation.
