Cable conductor of cabling and wiring products based on composite materials for transport systems

Abstract

The article deals with the issues of working out the technology of manufacturing cabling and wiring products that are used in railway transport systems. A cable conductor for a cable product, made on the basis of composite materials, was adopted as the object of research. The technology of production of composite billets and wire for cable products for subsequent drawing, as well as ways of obtaining them, is covered in detail. Special attention is paid to the problems of operation in railway transport, power transmission systems, which confirms the relevance of the research. The increase in the cost of the finished product is due to the violation of the technology, which is associated with the structural diversity of the layers of the composite long-length billet, determines the need to maintain the constancy of its plastic properties along the entire length. By means of a generalized mathematical model of the drawing process and on the basis of reference data, calculated parmeters of technological extracts were obtained for the layers of the composite billet to be drawn. The results of the research work made it possible to develop a methodology for calculating the technological modes of operation of the drawing machine and to determine the optimal technological parameters of the technological equipment.
