Abstract
A direct current cable termination apparatus for terminating a high voltage direct current cable, the apparatus includes a current-carrying device including a terminal portion of the direct current cable, the cable including an electrical conductor, a electrically insulating layer located outside of the electrical conductor, and a conductive shield located outside of the insulating layer and the electrical conductor; and a housing including a tubular outer shell with an inner periphery and formed by an electrically insulating and polymer-containing material. The current-carrying device is adapted to extend in the axial direction of the outer shell. Along at least a part of the axial extension of the current-carrying device the outer shell extends axially with a space between its inner periphery and the current-carrying device. The housing is adapted to separate the space from an atmosphere outside the outer shell, and the space is filled with an electrically insulating fluid.
