摘要:
A system and a process for continuously electrolytically coating a wire, useful for a high tension cable, is provided. The system includes a bath containing a precursor for an electro-ceramic coating on a wire and containing a cathodic connection, at least one motor connected to at least one motive assembly to impart movement to the wire. A power source provides high voltage and high current to the wire through the electrification device, and through the wire in the bath to the cathode connection via the aqueous electrolytic solution. The process includes electrifying bare wire with a high voltage and a high current, passing the electrified bare wire through a bath having a cathodic connection and containing an aqueous solution with a precursor for an electro-ceramic coating, and electrochemically reacting the wire with the precursor thereby generating a coated wire having an electro-ceramic coating on at least one surface.

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.
