Contributions for the modelling of submarine cables – current density and simplified modelling of wired layers
Abstract
This article researches two topics relevant for the development of accurate formulae able to estimate the ampacity of HVAC submarine cables.<br/><br/>Simplified formulae for estimating the current density distribution, which can be used for theoretical analyses, are developed and compared with the exact formulae.<br/><br/>The substitution of round wires by equivalent solid layers is tested and tuned by changing the permeability of the insulation and the resistivity of the of the substitution layer. The tuning of these two parameters allows obtaining similar results for both cases even for materials with high permeabilities, like steel.
