An SF/sub 6/ insulated semi-flexible transmission line is described which uses a corrugated aluminum enclosure to reduce cost and provide flexibility. Dielectric characteristics of a compact 1200 kV design (711mm (28 in) internal diameter enclosure) with SF/sub 6/ at 440 kPa (50 psig) are established through detailed field plotting and scale model tests. High voltage tests on 550 kV and 1200 kV prototypes then verified that a design using a smooth conductor with discrete flexible elements meets the performance and cost objectives.
