ABSTRACT:
A heat and oxidation resistant electrically conductive composite conductor has a core (1) made of copper or a copper alloy, an electrically conductive ceramics layer (2) around the core (1), and a nickel layer (3) on the exterior of the electrically conductive ceramics layer (2). Such a conductor is produced by coating the outer surface of the core copper alloy binder and covering the coated core with a nickel tape under an atmosphere of an inert gas or a reducing gas, welding the seam of the tape, clading the so formed conductor by a cladding die, and drawing the clad conductor. The composite conductor has a high conductivity which is not reduced even when the conductor is exposed to a high temperature operating condition.
