RESULTS OF EXPERIMENTAL STUDIES OF ELECTRICAL CHARACTERISTICS OF SIGNAL-LOCKING CABLES

With the increase of transportation volumes on the country's railways, the requirements for ensuring their safety and reliability are also increasing. One of the technical components of ensuring the safety and reliability of railway transport is the cable infrastructure of railways, in which a special role is given to signaling and interlocking cables. High-quality signal-locking cables must have characteristics that strictly comply with GOST requirements. The article presents the results of experimental studies and analysis of the electrical characteristics of transmission and mutual influences of signal-locking cables with single-wire and multi-wire conductors. It was prooved that the production of insulated conductors of signal-locking cables, as well as of any other symmetrical communication cables, is realized on an extrusion line equipped with automatic control systems, which ensures high stability of their electrical characteristics. Practical recommendations for the use of signal-blocking cables not only in railway transport, but also in other departments that use symmetrical communication cables are also provided in this study.
