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.

Abstract: A power cable having: a conductor and having: a first conductor section including an elongated first central element made of a first metal and a first outer metal structure made of a second metal surrounding the first central element, a second conductor section including the second metal, a weld metal located axially between the first conductor section and the second conductor section, wherein the first conductor section has a first axial end section extending to the weld metal, wherein the first axial end section includes: a central axially extending first metal member surrounded by the first outer metal structure, the first metal member including a first axial part made of the first metal and a second axial part made of the second metal, wherein the first axial part has a first end that is welded to the first central element and a second end that is welded to a first end of the second axial part, and wherein the second axial part has a second end, wherein the second end of the second axial part and the firs

Abstract: An underground power cable system including: an underground power cable, and a metallic mesh extending outside of and axially along the underground power cable.

Abstract: A power cable system including a power cable, and an evaporator pipe assembly extending along the power cable, wherein the evaporator pipe assembly having an inner liquid pipe including a pressurised liquid refrigerant, and an outer gas pipe arranged outside of and coaxially with the inner liquid pipe, wherein the inner liquid pipe is provided with a plurality of openings distributed along its length, and wherein the openings provide fluid communication between the inner liquid pipe and the outer gas pipe, allowing part of the pressurised liquid refrigerant to escape from the inner liquid pipe to the outer gas pipe and evaporate in the outer gas pipe, thereby cooling the power cable.

Abstract: A system and method for additively manufacturing splices and terminations for extra high, high, medium and low voltage power cable includes providing an additive manufacturing machine having at least one print head. Cable ends can be secured within a chamber from which atmospheric air can be evacuated and replaced with non-oxidizing gas. A scanning device can determine the composition and position of the various constituents of the cable ends, from which information a controller can determine the printing sequence and print a termination or splice portion.

Abstract: A laminated cable includes a metal laminate surrounding a cable core having first and second ends. Solder is applied adjacent the ends of the laminate, and is heated and subsequently cooled to form a metal seal. The solder can be melted in a plastic jacketing extruder as the extruder applies a plastic jacket over the metal laminate.
