Annotation: Questions, touching experimental researches of simulation of icing process on the conductor of overhead lines, are considered in the article. For achievement of purpose of researches developed and constructed experimental setting on the base of climatic chamber of laboratory of tests of build constructions and buildings of the DonNACEA. The method of comparative tests of traditional bi-metallic conductors in aluminium and steel is developed with the new types of compacted conductors in a climatic chamber for simulation of icing in a wind stream. It is set that for 5–6th ice districts in accordance with Chapter 2.5 PUE: 2006 a role of torsion of the conductor on intensity of ice load will be substantial, and a difference in weight of ice for the different values of the stiffness in torsion of the conductor can arrive at 25 %. Job performances are needed for further researches, related to the study of the icing on the conductor, and also development of measures with the purpose of providing of accident-free work of OPTL at ice and wind loads.
Keywords: overhead power transmission lines (OPTL), icing, conductor, stiffness in torsion, experimental investigations.
