Abstract

The development of UHV transmission lines of 1000 kV and above has created a number of new problems which necessitated the performance of a complex of theoretical, experimental and design studies as well as the development of new structural members for overhead lines. Most important are limiting voltage on cap-and-pin insulator unitsaf'a string, the stability of bundle conductors suspension, an increase in the reliability of insulator strings. The results of studies carried out in the USSR for solving these problems are presented in this report.
