Analysis of the insulated self-supporting conductor obstacle

Subject of research: In this paper, the analysis of the heterogeneity of current-conducting wires is carried out. Purpose of research: consideration of the need to take into account the design of a self-supporting insulated wire, namely the method of setting current-conducting cores in the form of a single core or a family of wires. Methods and objects of research: simulation of thermal processes occurring in a self-supporting insulated wire in the form of a single core and a wire family is carried out with the help of the software package ELCUT. When set in the form of a wire family, the modes of asymmetric load of the wire are also considered. Main results of research: analysis of cross-section temperature distribution, insulation and consideration of the heating of the outer wires showed that the influence of the adjacent phases is negligible. It is found that taking into account the real constructive state of the conductor has little influence on the temperature distribution along the cross section of the wire at a frequency of 50 Hz.
