Abstract

The invention discloses a high-strength pure copper cable and a fabrication method thereof. The cable comprises a pure copper conductor and a tensile component, wherein the tensile component comprisesa core part tensile fiber and a surrounding tensile fiber, the core tensile fiber is arranged at an axis of the cable, the pure copper conductor and the surrounding tensile fiber are arranged in a way encircling the core copper conductor, an insulation layer wraps the pure copper conductor, an internal sheath layer wraps an outer side of the surrounding tensile fiber, a shielding layer wraps an outer side of the internal sheath layer, an armoring layer wraps an outer side of the shielding layer, an outer sheath wraps the armoring layer, the cable is characterized in that the core tensile fiber and the surrounding tensile fiber both are made of carbon nanotube-polyvinyl alcohol fibers. Compared with the cable in the prior art, the cable tensile component prepared by the method has the advantages of more excellent tensile strength, so that the tensile strength of the cable is remarkably improved, cable weight is not reduced, and the application range is wider.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, in particular to a processing method for high-strength pure copper cables. Background technique [0002] A high-strength cable refers to a cable that can withstand a large tensile force, and its tensile force is generally between 10 kN and several hundred kilonewtons. In practical applications, high-strength cables generally have dual functions: 1) transmit power and electrical signals like ordinary cables, including a certain amount of electric power, high-frequency signals, data signals, etc.; 2) carry tension and play the role of cables. High-strength cables have broad application prospects in seabed exploration, mid-level space weather monitoring and forecasting, and long-distance communication. [0003] High-strength cables are mainly composed of two parts: electrical components and tensile components. An electrical component is a cable designed and built for its purpose....
