    • A method is provided for producing a superconductive electrical conductor, in which a layer of an yttrium-barium-copper oxide (YBCO) is applied as a superconductive material onto a textured metal substrate, and is subjected to a heat treatment. In order to produce a wire-shaped conductor, a textured metal substrate, provided as a strip (2), is initially shaped in its longitudinal direction around an elongate metal support (1) with a circular cross section to form a slotted tube (3) having edges extending in the longitudinal direction and adjoining one another at a slot (4). The slotted tube (3) is next closed by welding the slot (4) shut, and the closed tube (9) is then contracted by pulling until it bears on the support (1). The layer (12) of superconductive YBCO material is thereupon applied all around, and the heat treatment is finally carried out.
    • 提供了一种用于制造超导电导体的方法,其中将钇钡钡氧化物(YBCO)层作为超导材料施加到织构化金属基底上,并进行热处理。 为了制造线状导体,设置为条带(2)的有纹理的金属基底最初在其纵向方向围绕具有圆形横截面的细长金属支撑件(1)成形,以形成开槽管(3 )具有在纵向方向上延伸并且在狭槽(4)处彼此相邻的边缘。 接下来通过焊接狭槽(4)关闭开槽管(3),然后通过拉动使封闭管(9)收缩,直到其承载在支撑件(1)上。 然后将超导YBCO材料层(12)全部施加,最后进行热处理。
