Objective: Patented and experimentally fulfilled development of supported electric cables and wires’ successful protection from snow build-up, ice covering and possible breakages, caused by strong rushes of wind, was suggested for pilot installing in operation. It is known that, on average, the financial losses of our country from wire breakages amount to about 1 billion rubles. Nevertheless, some districts are left without heat and light, which demands the start of emergency electric power sources and sending the repair squads for power lines’ breakage elimination. Methods: Experimental tests were conducted under conditions close to natural, that is, in winter time and open air. Results: Original and simple implementation solutions of effective damping of possible wire oscillations corroborated the impossibility of resonant swinging of wires formation, which considerably increases the reliability of line functioning. Practical importance: Positive results, indicating a complex fulfillment of the set objective on wires’ protection were obtained, which demonstrate commercial efficiency of the study.
