摘要： A power induction device including at least one cable joint assembly (1) having: a first cable (2) with inner first conducting means (3), comprising first conductor means (21) cooled by first cooling means (22) and surrounding outer first electrical insulation (4); a second cable (5) having inner second conducting means (6) and surrounding outer second electrical insulation (7); one end of the first conducting means (3) being joined at a joint (8) to one end of the second conducting means (6), the outer electrical insulation (4, 7) of each cable not surrounding an end portion of its associated inner conducting means adjacent the one end of the latter; and polymeric electrically insulating means (9) surrounding the joint (8) and the end portions of the first and second conducting means (3, 6). The first electrical insulation comprises inner and outer layers of semiconducting material and an intermediate layer of insulating material. The invention also relates to a method of joining together two power cables in a power induction device.

摘要： A high voltage induction device including a power cable (12) comprising inner conducting means (13-15) and outer electrical insulation (20-22) having spaced apart inner and outer layers (20, 21) of semiconducting material and, positioned between the inner and outer layers, and intermediate layer (22) of electrically insulating material. The conducting means comprises conductor means (14) and cooling means (13) for cooling the conductor means (14) to improve the electrical conductivity of the conductor means. The inner layer (20) of semiconducting material is electrically connected to the conductor means and the outer layer (21) of semiconducting material is at a controlled electric potential along its length.
