Abstract
An electrically conductive wire for deep water transmission includes a first wire portion and a second wire portion. The first wire portion makes up one end of the wire, and is formed from a first metal. The second wire portion is formed from a second metal. The first metal has a higher ultimate tensile strength than the second metal. The first wire portion is used to support the weight of the second wire portion, thereby allowing the electrically conductive wire to be used in underwater or subsea power cables which may be freely suspended from their origin for providing electricity to electrical devices located in deep water or ultra-deep water.
Claims20
A power cable for deep water transmission comprising:
- at least one core, each core comprising:
- an electrically conductive wire having a first wire portion and a second wire portion welded together, wherein the first wire portion is formed of a first metal, is located at one end of the wire, and has a length of about 100 feet or greater, wherein the second wire portion is formed of a second metal, and wherein the first metal has a higher ultimate tensile strength than the second metal.
A method for making an electrically conductive wire, comprising:
- welding together a first wire portion and a second wire portion to form a wire;
- and
- rolling and drawing the wire to a desired size;
- wherein the first wire portion is formed of a first metal, is located at one end of the wire, and has a length of about 100 feet or greater after rolling and drawing;
- wherein the second wire portion is formed of a second metal;
- and
- wherein the first metal has a higher ultimate tensile strength than the second metal.
