Cable Upgrading Feasibility for Distribution Network Capacity Increase

Author

Abstract

Distribution networks globally face critical capacity constraints as urbanization and renewable integration drive load growth beyond the design limits of aging infrastructure, resulting in voltage violations, increased losses, and reliability risks. Confronting this challenge, this study analyzes the feasibility of strategic cable upgrades—specifically, increasing conductor cross-sections and adopting Cross-Linked Polyethylene (XLPE) insulation—as a targeted alternative to complete network reconstruction. To evaluate this solution, the research employs an integrated technical-economic model that combines electrical network simulation with financial analysis. The technical module quantifies performance gains in ampacity, losses, and voltage stability, while the economic module calculates key metrics, including Net Present Value (NPV) and Payback Period.
