초록 ▼

An electrically insulated conductor for carrying signals or current includes a solid or stranded copper core of various geometries with only a single electrically insulating and thermally conductive layer of anodized aluminum (aluminum oxide). The device is made by forming a uniform thickness thin sheet or foil of aluminum to envelop the copper or copper alloy core. The aluminum has its outer surface partially anodized either before or after forming to the core in an electrolytic process to form a single layer of aluminum oxide.

대표청구항 ▼

What is claimed: 1. An insulated electric conductor comprising: a copper core; a uniform thickness thin sheet of aluminum mechanically formed to envelop the copper core; and an outermost dielectric layer of aluminum oxide with no further layer covering the aluminum oxide layer, the aluminum oxide layer formed by anodizing the outer surface of the thin sheet of aluminum. 2. The insulated electric conductor of claim 1 wherein the outer surface of the aluminum is anodized before forming the aluminum sheet to the copper core. 3. The insulated electric conductor of claim 1 wherein the copper core comprises a plurality of discrete copper strands. 4. The insulated electric conductor of claim 1 wherein the dielectric layer of aluminum oxide is formed in an electrolytic process. 5. The insulated electric conductor of claim 1 wherein the dielectric layer of aluminum oxide has a smooth outer surface. 6. The insulated electric conductor of claim 1 wherein the dielectric layer is substantially free of holes and voids. 7. The insulated electric conductor of claim 1 wherein the dielectric layer is formed on only an outer portion of the thin sheet of aluminum by only partially anodizing the outer surface of the thin sheet of aluminum. 8. The insulated electric conductor of claim 1 wherein the dielectric layer extends only part way through the thin sheet of aluminum. 9. The insulated electric conductor of claim 8 wherein the thickness of the dielectric layer is controlled by selectively halting the anodizing process using a rinse to remove an electrolytic agent from the thin sheet of aluminum. 10. The insulated electric conductor of claim 8 wherein the dielectric layer comprises a substantially homogeneous layer of aluminum oxide. 11. The insulated electric conductor of claim 1 wherein the thickness of the aluminum sheet prior to anodization varies less than plus/minus twenty percent. 12. An insulated electric conductor formed by enveloping a copper core with a uniform thickness thin sheet of aluminum and partially anodizing the outer surface of the thin sheet of aluminum to form a single dielectric layer of aluminum oxide that defines the outermost layer of the insulated conductor with no further layer covering the aluminum oxide layer and electrically insulates the copper core. 13. The insulated electric conductor of claim 12 wherein the outer surface is partially anodized to form a dielectric layer of aluminum oxide substantially free of holes or voids extending into the outer surface. 14. The insulated electric conductor of claim 12 wherein the conductor is formed by mechanically forming the thin sheet of aluminum to envelop the copper core.
