Electroceramic coating of a wire for use in a bundled power transmission cable
First Claim
1. A cable for power distribution applications, the cable comprising:
- a plurality of wires bundled into a cable and extending along a central longitudinal axis of the cable;
the plurality of wires comprised of interior wires and peripheral wires with the peripheral wires surrounding the interior wires, at least one peripheral wire being a coated wire having deposited thereon a high emissivity coating, the high emissivity coating comprising at least one metal oxide other than aluminum oxide and at least 10 weight percent aluminum oxide, the coated wire having an emissivity greater than or equal to 0.5 and a surface area at least 20 times greater than the surface area of a bare peripheral wire prior to being coated with the high emissivity coating.

Abstract
A cable for power distribution applications includes a plurality of wires bundled into the cable. The plurality of wires typically is comprised of interior wires and peripheral wires with the peripheral wires surrounding the interior wires. At least one wire is coated with a high emissivity coating that includes at least 10 weight percent aluminum oxide and a metal oxide other than aluminum oxide. Characteristically, the wire coated with the high emissivity coating has an emissivity greater than about 0.5 in the infrared region of the electromagnetic spectrum and a surface area at least 50 times greater than the surface area of a bare wire prior to being coated with the high emissivity coating.
