美国超导公司（AMSC）开发了用于商业和军事应用的低成本第二代高温超导（2G HTS）线材的基础技术和生产线。该生产线基于宽HTS带材的卷到卷处理，使用滚动辅助双轴织构化基板（RABiTS（TM））作为模板，金属有机沉积（MOD）作为HTS层。AMSC的宽带工艺是一种低成本的制造技术，因为在制造工艺的最后阶段，通过将宽带切割成较窄的宽度，在单个制造工序中生产多根电线。工业标准的4.4 mm宽导线通过将金属箔（例如铜、不锈钢或任何其他材料）层压到HTS插入导线来生产，并且被选择以针对特定应用定制导线的电、热和机械性能。层压的4.4毫米宽的导线被称为“344超导体”。“在本文中，我们总结了AMSC的制造能力的现状，目前正在生产的电线的性能，以及AMSC的制造方法的成本和技术优势。最后提出了今后提高电性能的研究和开发方向。(C)2009 Elsevier B.V.保留所有权利。
American Superconductor Corporation (AMSC) has developed the base technology and a manufacturing line for initial volume production of low-cost second generation high temperature superconductor (2G HTS) wire for commercial and military applications. The manufacturing line is based on reel-to-reel processing of wide HTS strips using rolling assisted bi-axially textured substrate (RABiTS (TM)) for the template and Metal Organic Deposition (MOD) for the HTS layer. AMSC's wide strip process is a low cost manufacturing technology since multiple wires are produced in a single manufacturing pass by slitting the wide strip to narrower width in the last stage of the manufacturing process. Industry standard 4.4 mm wide wires are produced by laminating metallic foils, such as copper, stainless steel or any other material, to the HTS insert wire, and are chosen to tailor the electrical, thermal and mechanical properties of the wire for specific applications. The laminated, 4.4 mm wide wires are known as "344 superconductors."In this paper, we Summarize the status of AMSC's manufacturing capability, the performance of the wire presently being produced, as well as the cost and technical advantages of AMSC's manufacturing approach. In addition, future direction for research and development to improve electrical performance is presented. (C) 2009 Elsevier B.V. All rights reserved.
