Abstract

En krafttransformator (1) omfatter en transformatorkjerne viklet med en høyspentkabel som er sammensatt av en kjerne som har en flerhet av tråddeler (112), et indre halvledende sjikt (l 13) som omgir kjernen, et isolasjonslag eller sjikt (l 14) som omgir det indre halvledende sjiktet (l 13), og et ytre halvledende sjikt (115) som omgir isolsajonslaget (l 14) og hvor viklingen er utstyrt med avstandsstykker (4, 12) anordnet for å skille hver kabelvinding i den radiale retningen i viklingen for å danne aksiale sylindriske kjølekanaler (3).A power transformer (1) comprises a transformer core wound with a high voltage cable composed of a core having a plurality of wire parts (112), an inner semiconducting layer (13) surrounding the core, an insulation layer or layer (14) surrounding the inner semiconducting layer (l 13) and an outer semiconducting layer (115) surrounding the insulation layer (l 14) and wherein the winding is provided with spacers (4, 12) arranged to separate each cable winding in the radial direction of the winding to forming axial cylindrical cooling ducts (3).
