YBa/sub 2/Cu/sub 3/O/sub x/ (YBCO) 涂层导体已在 SuperPower 建立的中试规模设施中生产出 100 m 长度。除了将涂层导体扩大到具有高临界电流的长长度之外，我们还修改了基本导体，以增强现场性能和降低交流损耗。此外，我们的涂层导体已采用实际配置生产，宽度为 4 毫米，并带有环绕铜稳定器。首先将导体切成 4 毫米宽，然后进行电镀以施加铜稳定剂。完整导体的机械和电气性能均经过精心测试。向住友电气工业公司提供了 61 m 4 mm 宽的环绕铜稳定导体，住友电气工业公司使用该导体制造了 1 m 电缆。该电缆表现出 HTS 导体所报告的最低交流损耗。 SuperPower 还制造了一个带有 7.4 m 涂层导体的扁平线圈，在 77 K 时产生了 0.28 T 的最大磁场。
YBa/sub 2/Cu/sub 3/O/sub x/ (YBCO) coated conductors have been produced in 100 m lengths in pilot scale facilities established at SuperPower. In addition to scaling up coated conductors to long lengths with high critical current, we have modified the basic conductor for enhanced in-field performance and low ac losses. In addition, our coated conductors have been produced in practical configurations in 4 mm widths and with a surround copper stabilizer. The conductors were slit first to a 4 mm width and then subjected to electroplating to apply the copper stabilizer. Mechanical and electrical properties of the complete conductor have been elaborately tested. 61 m of 4 mm wide, surround copper stabilized conductor was provided to Sumitomo Electric Industries who fabricated a 1 m cable using the conductor. The cable exhibited the lowest ac losses reported with HTS conductors. SuperPower also fabricated a pancake coil with 7.4 m of coated conductor, which generated a maximum magnetic field of 0.28 T at 77 K.
