Abstract

The objective of this article is to compare the shielding characteristics of the most applicable signal-blocking cables designs. In this paper, based on calculations and experimental studies, a comparative analysis of the shielding characteristics of cables with a solid pressed screen and a screen consisting of an aluminum-polyethylene tape and a layer of aluminum wires is performed. Special attention is paid to the characteristics of the influence of external electric fields. Measurements of the ideal protective action coefficient of signal-blocking cable samples were made, and an estimated calculation of shielding attenuation was performed. For a comparative assessment of the influence of external transverse high-frequency fields, measurements of transient attenuation at the near end were made on samples of signalblocking cables under study. It is shown that the shielding characteristics of cables with a solid aluminum screen are better than those of cables with a screen made of aluminum-polyethylene tape and aluminum wire layer. Recommendations are given – on electrified railways, preference should be given to signal-blocking cables with a solid aluminum screen.
