Abstract

The invention discloses a gradient copper-based alloy cable conductor, which consists of a core layer and a skin layer, wherein the core layer and the skin layer form a double-metal concentric circle structure; the core layer is a copper-based alloy; the skin layer is pure copper; and the conductor is cast by a double-layer composite material one-step coating device. With the double-metal concentric circle structure, the gradient copper-based alloy cable conductor has high interface metal atom lattice distribution transitivity, high crystal bonding strength, ordered crystalline phase structure, high purity, high electrical performance, tight core layer and skin layer bonding strength and high mechanical performance compared with the conventional non-gradient copper-based alloy cable conductor such as copper clad steel, copper clad aluminum and aluminum clad steel.

Description

technical field [0001] The invention relates to a gradient copper-based alloy cable conductor and a manufacturing method thereof, belonging to the technical field of cable manufacturing. Background technique [0002] A cable (electric cable; power cable) is made of one or more mutually insulated cable conductors covered with insulation and protective layers, and is a wire that transmits power or information from one place to another. The cable conductor is the core part of the cable. [0003] The cable conductor has three functions: transmission of electric energy, transmission of signals, conversion of electric energy and magnetic energy. For power transfer, the most important factor is resistance. For signal transmission, the most important factor is attenuation. For electrical and magnetic energy conversion, the most important factor is hysteresis. Among the mechanical properties of the cable, elongation, tensile strength, elastic limit, yield limit, fatigue limit, be...
