Working up the technical specifications for self-bearing isolated wires in which mechanical load is divided uniformly between all (four) working threads. Analysis a reference information, proceedings of testing the development types. Working up the accounts for equivalent diameters, permissible mechanical load and electrical operation factors and nominal dimensioning of wires. As a result the nomenclature of wires with mechanical and electrical figures has been obtained. Have been summarized requirements for production, testing and use of wires. The system of wires that is under developing is characterized by lack of bearing wire (or rope). All mechanical load is divided uniformly between all isolated wires that are stranded into a braid. In a present system rope consists of four wires the same cross-sections. Neutral wire and phase wires have round shape, are thickened and fulfilled from the same material - tough aluminum. These wires are characterized by a great mechanical strength. This system is used in power engineering for power leads and lighting power circuits of alternating current with voltage up to 380 V, rated frequency, and atmospheric temperature in a range from +45 °С to -45 °С.
