A 345-kV PPP-insulated cable was subjected to a two-year accelerated life test program at the EPRI Waltz Mill Cable Test Facility. Testing started in November 1985 and was successfully completed in September 1988. The program included conductor temperatures ranging from 85{degrees}C to 105{degrees}C and line-to-line voltages from 362 kV to 474 kV. Cyclic testing was performed during 17 of the 24 months. Dissipation factor measurements were made throughout the program. The measurements indicated no deterioration of the cable or splices as a consequence of the high temperatures and voltages applied to them in this test program. 2 refs., 24 figs.
