Progress in evaluating the technical feasibility of SF/sub 6/-insulated cables and circuit breakers for HVDC systems is reported. During this reporting period a new test setup was completed. An assembly jig was designed and fabricated. Model cable up to 20-ft length can be assembled complete outside the test tank. Components to extend the test tank to accommodate a 20-ft model cable have been obtained. A report was drafted on the effect of material selection as well as processing into insulators on the long-term dielectric performance of the insulator. The vertical leaf expansion joint design was improved by replacing the Alcuplate copper-to-aluminum transition piece with nickel plating on the aluminum parts. The joint was fatigue tested with condition which simulate almost 2 1/2 cycles of temperature excursions each day for the 40 year design life of the line. Electrical tests of the joint are in progress.
