Abstract :
This paper is the second part of an investigation on the new enlargement law for HVDC cables developed by the authors. The previous Part 1 has illustrated the theoretical derivation of this law and its application to enlargements over cable length. The present Part 2 is dedicated to the enlargement over cable radius and to its noteworthy aspects, that are essentially associated with the complicated function HDC. These aspects are mainly relevant to the role played by cable conductor losses, or equivalently by conductor temperature. They are deeply investigated here via a series of three radial enlargements for HVDC extruded cables, that involve conductor cross-section and insulation thickness only: this enables focusing the attention on the HDC function, that includes the dependence of the enlargement law on the radial cable geometry.
