A cable joint arrangement, comprising: a cable casing (11) comprising a metallic envelope (12), a first cable (1) provided with a first conductor (3) and extending into said envelope (12) through a first opening thereof, a second cable (2) provided with a second conductor (4) and extending into said envelope (12) through a second opening thereof, wherein the first conductor (3) is connected to the second conductor (4) inside said casing (11), wherein each cable (1, 2) is provided with an electrically conducting screen (7, 8) that surrounds the conductor (3, 4) thereof and conducts a screen current caused by inductance generated by the conductor (3, 4), and wherein said envelope (12) is in electric contact with at least one of said screens (7, 8), a connection means (15) electrically connected to at least one of said screens (7, 8) and conducting said screen current to a corresponding screen of another cable. The connection means (15) comprises a separate electric conductor (18) arranged to carry said screen current while by-passing a major part of the metallic envelope (12) as screen current carrier. |
