A cable joint assembly (1), preferably for high temperature superconducting power cable, has: a first cable (2) with an inner first cooled conductor (3), and surrounding outer first electrical insulation (4); a second cable (5) having inner second preferably cooled conductor (6) and surrounding outer second electrical insulation (7); one end of the first conductor (3) being joined at a joint (8) to one end of the second conductor (6), the outer electrical insulation (4,7) of each cable not surrounding an end portion of its associated conductor; and a polymeric electrically insulator (9) surrounding the joint (8) and the ends of the first and second conductors (3, 6). The first electrical insulation comprises inner and outer layers of semiconducting material and an intermediate layer of insulating material and an intermediate layer of insulating material, figure 2, not shown. |
