Abstract

The mechanism of vertical-arrayed double-bundle transmission-line conglutination is studied in this paper through experiments on a laboratory-based physical model with a 230-m span. Based on the equivalence principle, the conglutination problem in real-world transmission lines has been reproduced in high-voltage and heavy-current experiments where the test circuit is compensated by a series capacitor, so that the output current is continuously adjustable by the voltage regulator and power current transformer. This paper presents, in detail, the experiments carried out, and demonstrated the threshold factors associated with the conglutination phenomenon. The investigation revealed that the number one factor contributing to transmission-line conglutination is the electromagnetic force, which, in turn, is affected by the space between the lines; initial sag and ambient temperature also play important roles. The research results with a thorough understanding of the mechanism of transmission-line conglutination can help provide an understanding of the mechanisms and will enable conduction of numerical analysis of the phenomenon.
