Abstract

In the present study, our emphasis was directed towards the fabrication process of long multi-core superconducting wires, each spanning several hundred meters. These wires feature an in situ MgB core, an ex situ MgB barrier, and a copper shield. The cost-effectiveness of these constituent materials, coupled with a judicious arrangement of internal components, facilitates the utilization of an economical shielding material for the resulting wire. Our ongoing efforts have successfully yielded several hundred-meter-long wire sections possessing favorable superconducting characteristics, making them suitable for self-field applications, such as direct current (DC) power lines.

摘要

在本研究中，我们重点关注长的多芯超导线材的制造工艺，每根线材长度达数百米。这些线材具有原位MgB芯、异位MgB势垒和铜屏蔽层。这些组成材料的成本效益，加上内部组件的合理布置，便于为所得线材使用经济的屏蔽材料。我们持续的努力已成功生产出数百米长且具有良好超导特性的线段，使其适用于自场应用，如直流（DC）电源线。
