Annotation: Questions of estimation of resource of conductor/clamp systems for overhead power lines (OPL) at galloping of conductors is examined in the article. The certainly-element model of fittings was created by means of design in the SolidWorks. The static calculation of fittings on loading from galloping of conductors exposed large stress in the area of contact of U screw-bolt and staple, and also in the places of bend of screw bolt and in the area of the first coil of screw-thread. Stress on some areas exceed the limit of fluidity in 2 times. The executed calculation on the fatigue of fittings allowed to set that the tireless resource of knot at the most unfavorable terms of frequent galloping can make no more than 1 year of work. Offered to recommendation on the increase of reliability of conductor/clamp systems.
Keywords: overhead power lines (OPL), conductor/clamp systems, resource, fatigue, tensely-deformed state, numeral design.
