Design and Installation of a 138-KV, High-Pressure, Gas-Filled Pipe Cable Utilizing Segmental Aluminium Conductors

This paper presehits the results of further developments of 138-kV cable impregnated with extra-high-viscosity oil, as well as those of joining aluminum conductors and terminal ferrules by the inert gas shielded arc welding method. Welding the conductors in the presence of heavy oil had presented the chief deterrent to commercial utilization of cable containing alumliinum conductors. Success of these investigations has resulted in installation of a 2.74 mile (4.41 km) portion of The Detroit Edison Company Medina-Stephens 120-kV line, commissioned in November 1971. That installation is reported upon herein.
