Economic optimization of power cable size

This technical document outlines the economic optimization principles governing the sizing of electric power cables. It provides a systematic methodology for engineers and designers to determine the most cost-effective conductor cross-sections across various voltage levels and installation scenarios. The approach integrates initial capital expenditures with long-term operational costs, including energy losses over the equipment's lifespan, to guide decision-making processes. By establishing clear criteria for balancing investment against efficiency, the text supports the selection of cable dimensions that minimize total cost of ownership without compromising safety or performance requirements. The guidelines apply to diverse applications involving power transmission and distribution networks, ensuring consistency in technical evaluations. This resource serves as a reference for calculating optimal sizes based on load profiles, ambient conditions, and material costs, facilitating informed choices in infrastructure development. It emphasizes the importance of lifecycle analysis in selecting cable specifications, promoting sustainable and economically viable electrical systems through standardized calculation procedures applicable globally.
