Electroceramic coating of a wire for use in a bundled power transmission cable

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 electro-ceramic coating comprising at least one of titanium oxide and zirconium 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 100 times greater than the surface area of a bare peripheral wire prior to being coated with the high emissivity coating.

A coated wire comprising:

• a metal wire;
• and
• a coating chemically adhered directly on the metal wire, the coating comprising at least one metal oxide other than aluminum oxide and at least 10 weight percent aluminum oxide, the coating 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 wire prior to being coated with the coating.
