Abstract

I en elektrisk kabel, designet for bruk som en elektrisk vikling, slik som en transformator eller reaktorvikling, er en elektrisk ledende kjerne (2) anordnet slik at den er i kontakt med et indre, første halvledende sjikt (4) som omgir kjernen. Et første isolasjonssjikt eller lag (6) er anordnet på utsiden av det første halvledende sjiktet og omgir dette. Et ytre andre halvledende sjikt (8) er anordnet på utsiden av det første isolasjonssjiktet og omgir dette. Det er også tilveiebrakt innretninger (16, 18) på utsiden av det andre halvledende sjiktet for å jorde kabelen for vekslende spenning og/eller pulsspenning kontinuerlig langs i det minste en vesentlig del av dens lengde.In an electrical cable, designed for use as an electrical winding, such as a transformer or reactor winding, an electrically conductive core (2) is arranged so that it is in contact with an inner, first semiconducting layer (4) surrounding the core. A first insulating layer or layer (6) is arranged outside the first semiconducting layer and surrounds it. An outer second semiconducting layer (8) is disposed on the outside of the first insulating layer and surrounds it. Also provided are means (16, 18) on the outside of the second semiconducting layer for grounding the alternating voltage and / or pulse voltage cable continuously along at least a substantial portion of its length.
