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 of the sleeve; wherein the conductor comprises a cavity (6) extending longitudinally along the conductor and having an opening at one end; wherein the cavity is arranged for accommodating a heat-pipe, the heat-pipe comprising a fluid being contained in a closed system arranged for transferring heat along the bushing, and wherein the cavity is arranged for allowing the heat-pipe to be introduced into and removed from said cavity via its opening.
