Abstract (en)
The present invention relates to an electrical insulator bushing (1) comprising: an electrically insulating sleeve (2) having a central longitudinal through hole (4) surrounding a central longitudinal axis (5) of the bushing; and an electrical conductor (3) positioned through the central longitudinal through hole (4) of the sleeve (2); wherein the conductor (3) comprises at least a part of an eccentrically located cavity (6) extending longitudinally along the conductor (3); wherein the cavity (6) is at least partly filled with a fluid, the fluid being contained in the cavity (6) in a closed system; whereby the cavity (6) forms a heat pipe arranged for transferring heat within the bushing.
