Abstract
Cables including conductors formed form ultra-conductive copper wires which have a lower temperature coefficient of resistance are disclosed. Methods of making the cables including conductors with ultra-conductive copper wires are further disclosed.
Claims14
A cable comprising:
- a conductor comprising one or more wires formed from ultra-conductive copper;
- and
- wherein the ultra-conductive copper is formed from pure copper and a nano-carbon additive;
- and
- wherein the one or more wires exhibit a lower temperature coefficient of resistance than wires formed from only pure copper.
2 more elements
A method of forming a cable with a lower temperature coefficient of resistance, comprising:
- depositing a nano-carbon additive onto a plurality of copper metal pieces;
- processing the plurality of copper metal pieces together to form ultra-conductive copper;
- drawing the ultra-conductive copper into one or more wires;
- and
- forming a cable from the one or more wires.
