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.

The article deals with the production of cable and wire products and the operation of cable processing equipment. The technological parameters of cable machines are analyzed by maintaining the range established by the regulatory documentation, and the main task of ensuring the efficiency of the technology is formulated. The requirements for automated electric drive of cable equipment are analyzed, considering the harsh modern operating conditions of cable products. The work of modern cable equipment with a high level of automation of the technological process and existing cable machines with a service life of more than 10 years is considered. The possibility of creating a unified automatic control system for both the entire technological process and a separate technological operation by creating a flexible control system for a separate cable machine with the further formation of a full-scale digital environment for the entire cable enterprise is analyzed. The developed generalized requirements for the automated electric drive of the cable machine made it possible to conduct research on specific cable equipment the VSK-13 drawing machine by creating a simulation model, and the obtained results of mathematical modeling gave good results on the computational experiment of the electromechanical system of the VSK-13 drawing machine.

This work is devoted to the development of an automated transfer switch (ATS) for the 6/0.4 kV substation. The work is relevant due to the introduction of automation and the replacement of electromechanical equipment with microprocessor devices in the power systems. At the lower (field) level, automation is driven by the use of programmable logic controllers (PLCs) and various smart sensors. The possibility of using modular PLC in automation systems is considered. Developed are an algorithm and a program for the implementation of automated regulation of the application of automatic transfer switches at a substation using the recommendations of the IEC 61131.3 “Programming languages of programmable logic controllers” standard.
