This study evaluated the technical and economic suitability of many of the underground power transmission systems that may be available in the 1990's. The systems considered included cellulose-, polyproplyene-, and gas-insulated cables, oil-filled cables and cryogenic cables for 345 kV to 765 kV ac or dc systems and superconducting cables for 230 kV ac systems and 300 kV dc systems. The results of this economic evaluation and limitation on applying these results to other underground transmission applications are presented. (LCL)
