Overview of the transmission line construction process

摘要

This paper outlines various procedures followed in the construction of transmission lines designed by Los Angeles Department of Water and Power (LADWP). The transmission line network designed or constructed by LADWP spans about 3500 circuit miles with voltages ranging from 115 kV AC to 1000 kV DC. Since most lines constructed by LADWP in recent years have been extra-high-voltage AC, this paper emphasizes the construction of 500 kV AC transmission lines built in the southwest United States. The paper presents some concepts and empirically developed practices that have proven successful over many years of transmission line construction by LADWP.
