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).
