Abstract

The present invention relates to a direct current transmission system (1) and a method for preparation comprising an electrical conductor layer (2) an inner semiconductive layer (3) covering the conductor layer an insulation layer provided on the semi conductive layer comprising laminated polymer material and impregnated with a high viscosity fluid and comprising an inner part (4) a middle part (5) an outer part (6) and an outer semi conductive layer (7) covering the insulation layer. The inner part has a first thickness the middle part has a second thickness and the outer part has a third thickness whereby the second thickness is greater than the first thickness and greater than the third thickness. The laminated polymer material within each parts has a constant thickness and constant ratio of polymer to laminated material and wherein at least one of the parts has a thickness ratio of less than 35%.
