Increasing electricity consumption in cities and the impossibility ofdeveloping high-pressure lines in urban areas and important andexpensive places have encouraged engineers to use high-capacityconductors. This article first introduces the history and reasons forusing high-capacity conductors. The difference between ACSRconductors and high-capacity conductors is expressed in terms ofbehavioral characteristics. Then, the technical comparison of highcapacityconductors with ACSR conductors has been done. Then, theeconomic study of the use of high-capacity conductors to increasepower transmission is stated. Despite the lower price of ACSRcompared to high-capacity conductors, the study shows the advantageof using high-capacity conductors to increase the capacity of existinglines. In the next section, losses in high-capacity conductors aredescribed, and in order to investigate and compare losses with thereplacement of high-capacity conductors, we use a practical example.At the end, conclusions and suggestions are given.
