Abstract
A power cable includes a conductor having a first section, a second section, and a weld metal located axially between the sections. The first section includes a central element made of a first metal and an outer structure made of a second metal surrounding the central element. The second section includes the second metal. An axial end section of the first section extends to the weld metal and includes a central axially extending member surrounded by the outer structure, wherein the member includes a first axial part made of the first metal and a second axial part made of the second metal. The first axial part has a first end welded to the central element and a second end welded to a first end of the second axial part. A second end of the second axial part and the outer structure are welded to the second section via the weld metal.
