A Comparison Between Two Different Designs of Bare Single-Layer Steel-Reinforced Aluminum Conductor

Two different designs of bare single-layer steel- reinforced aluminum conductor are examined both by theoretical techniques and by experimental methods. An approximate model is developed which uses a new approach for solution for impedances of such conductors. A comparison between two different commercial designs is effected with the aid of the model, and the results are evaluated in the light of experimental evidence. Suggestions are made for comparing conductor designs and also for the improvement of designs.
