Аннотация

This report describes the work carried out to develop a delta 420 kV compact line with 5 m phase spacing, utilising line surge arresters and eliminating shield wires. Long term audible noise measurements were taken on a full-scale outdoors test line. Special grading rings were developed and tested. The design is based.on tension towers only, to overcome the clearance problems of short insulator strings on compact towers.
