Research on the Improvement of Cable Ampacity in Dense Cable Trench

open access: yesEnergies
Due to the influence of many factors, distribution cables are often densely placed at the bottom of the cable trench. As a result, it is easy for distribution cables to become the thermal bottleneck of the whole transmission line. To address this dilemma,

Finite element modeling of direct-buried high-voltage cable ampacity considering dynamic soil thermal properties [PDF]

open access: yesScientific Reports
Traditional ampacity evaluation for direct-buried cables often assumes static soil thermal resistance, which obscures actual operating margins. To address this, a new electromagnetic-thermal coupled finite element model for cross-linked polyethylene ...

Configuration Optimization of Cables in Ductbank Based on Their Ampacity ()

open access: yesJournal of Power and Energy Engineering, 2018
Electrical power companies are using more underground cables rather than overhead lines to distribute power to their customers. In practice, cables are generally installed in some compact ductbanks. Since the cost of underground cables is very expensive, using the entire space of a ductbank is extremely important.
