Energy analysis of the basic materials utilized in electric power transmission systems
The energy content per mile of installed underground and overhead power transmission systems has been calculated for the following types of systems: self-contained oil-filled cables; HPOF pipe-type cables; extruded dielectric cables; compressed-gas-insulated systems; overhead lines (ac and dc) and two proposed superconducting systems (ac and dc). The system operating voltages analyzed included 138, 230, 345, 500, 765 and 1,200 kV for ac systems, but all systems were not analyzed at the higher voltages. The dc overhead lines operated at +-200, +-400, +-600 and +-800 kV. Total installed energy content for these systems ranged from 4 x 10/sup 9/ to 1.2 x 10/sup 11/ Btu per mile. Installation energy requirements were generally 10% or less of the inherent system energy content based on the materials used in each system. Most of the energy content in each system can be attributed to the metallic components; plastic and insulating oil also contribute significantly. The energy content of 36 materials and basic products, in terms of Btu per ton, was calculated as part of this study. Substitution of conductor materials (e.g., aluminum for copper) in cable systems resulted in changes in the total system energy content on the order of 15%.
