Abstract

The invention discloses a highly conductive cable with an improved conductor structure and a manufacturing method thereof, which belongs to the field of cables. In the highly conductive cable with the improved conductor structure, a plurality of conductors are stranded at the periphery of a concentric circle or non-concentric circle core wire to be manufactured into stranded conductors; the stranded conductors are embedded into grooves of hollow, circular and porous multi-groove conductor mounting brackets, or, flat conductor mounting brackets embedded with the stranded conductors are encircled at the periphery of a hollow and circular screw, and then are packed by polyurethane (PE) tapes or PE wire mylar, or, a plurality of flat conductor mounting brackets embedded with the stranded conductors are overlapped into multi-core highly conductive cable core wires; the outer edges of the multi-core highly conductive cable core wires are packed by a porous insulating tape; and the multi-core highly conductive cable core wires and a hollow special-shape screw are evenly encircled at the periphery of the hollow and circular screw at intervals. By adopting the highly conductive cable with the improved conductor structure, the area of each conductor is minimized; the skin effect is maximized; the current-carrying capacity of the area of the conductor is increased; a copper material is saved by about 70 percent; and simultaneously, the porous conductor mounting brackets are adopted, thereby, the highly conductive cable with the improved conductor structure is beneficial to ventilation, reduces temperature rise and has an effect of increasing the current-carrying capacity.

Description

technical field [0001] The invention relates to the field of cables, more specifically, to a high-conductivity cable with an improved conductor structure and a manufacturing method thereof. The improved conductor structure can save nearly 70% of copper material. Background technique [0002] Today's climate change is unpredictable, sometimes there are flash floods, storms, tsunamis, and earthquakes, and Changming's technology is also difficult to cope with. Superconducting cables have entered the experimental period, which is a great boon for energy conservation. Due to the cumbersome production process and high cost, it will take at least 20 to 30 years to replace underground high-voltage cables. The ampacity of high conductivity cables is 1 to 2 times that of traditional cables, but it is still not ideal. [0003] Existing wires and cables except for a single conductor, most of the wires and cables composed of multiple conductors have to be twisted once or more times. As ...
