Progress in Generator Leads: Economical Application of Forced Cooling

Conductors for high electric currents have had a very interesting evolution extending through many years. As conditions changed, the application engineer developed types which most economically met the requirements of the period. This paper recounts in part the activities of the authors in this field since 1925. It details some of the most important developments as they took place at the Cleveland Electric Illuminating Company, and brings out the economic considerations which justified the various applications of forced cooling.
