The Effect of Cable Duct Diameter on the Ampacity of High-Voltage Power Cables

Published by Filip RATKOWSKI1,2, Michał KOŁTUN2, Stanislaw CZAPP1, Gdańsk University of Technology (1), Eltel Networks Energetyka SA (2). ORCID: 1. 0000-0002-4698-9729, 3. 0000-0002-1341-8276 Abstract. The ampacity of power cables depends, among others, on the conditions of heat dissipation from the cable to the environment. Cables are usually laid directly in the ground, but in someContinue reading “The Effect of Cable Duct Diameter on the Ampacity of High-Voltage Power Cables”
