Abstract: A direct current cable termination apparatus for terminating a high voltage direct current cable, the apparatus comprises a current-carrying device (102; 502) comprising a terminal portion (104; 504) of the direct current cable, the cable at least comprising an electrical conductor (106; 506), a electrically insulating layer (108; 508) located outside of the electrical conductor, and a conductive shield (110; 510) located outside of the insulating layer and the electrical conductor; and a housing (111) comprising a tubular outer shell (112) with an inner periphery (114) and formed by an electrically insulating and polymer-containing material. The current-carrying device (102; 502) 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 (118) between its inner periphery (114) and the current-carrying device (102; 502). The housing (111) is adapted to separate the space (118) from an atmosphere outside (120) the outer shell, and the space is filled with an electrically insulating fluid (125). The outer shell (112) has a first end portion (132) and a second end portion (134). The conductive shield (110) terminates inside the outer shell. A first part (142; 542) of the terminal portion (104; 504) of the cable has the conductive shield (110; 510), whereas a remainder part (144; 544) of the terminal portion (104; 504) of the cable has the conductive shield removed. The apparatus comprises at least one field grading material layer (150; 550) positioned around the current-carrying device (102; 502), the at least one field grading material layer being electrically connected to the conductive shield (110; 510) and electrically connectable to the electrical conductor (106; 506). An electric installation comprising the above-mentioned apparatus.
