稀土元素RE - ba - cu - o （RE：稀土元素）超导体涂层导体在液氮温度下即使在高磁场下也具有很高的临界电流密度，因此有望在许多电力应用中得到应用。在研制具有高超导性能的长涂层导体的工艺方面做了许多努力。在日本，新的涂层导体加工发展五年国家项目于2003财年启动，计划于2007财年结束。该项目的预期目标是500米长的磁带，高Ic值为300 a cm−1 W−1，生产速率为5 m h−1等。近年来取得了显著的进展，例如长度超过100 m的高Ic值超过100 A cm−1 W−1的长磁带。长磁带已成功地实现了不止一个机构，而是几个机构。此外，使用YBCO导体的螺线管型磁铁和电力电缆已经被证明是应用的初步结果之一。对于涂层导体的未来应用计划，提出了以下使用涂层导体的电力器件：(1)电力电缆，(2)变压器，(3)电动机，(4)故障限流器，(5)制冷机等。
Coated conductors using RE–Ba–Cu–O (RE: rare earth element) superconductors have been expected to be used in many electric power applications since they have a high critical current density at liquid nitrogen temperature even under high magnetic fields. Many efforts have been made in development of processing for a long coated conductor with high superconducting performance. In Japan, the new five-year national project for development of coated conductor processing was started in FY2003 and was scheduled until the end of FY2007. The expected goals in this project are 500 m long tapes with a high Ic value of 300 A cm−1 W−1 at a production rate of 5 m h−1 etc. The progress in recent years is remarkable, such as long tapes over 100 m in length with high Ic values of over 100 A cm−1 W−1. The long tapes have been successfully realized by not only one institution but several. Additionally, a solenoid type magnet and a power cable using YBCO conductors have already been demonstrated as one of the preliminary results for applications. For the future plans of coated conductor applications, the following power devices using coated conductors have been proposed: (1) power cable, (2) transformer, (3) motor, (4) fault current limiter, (5) cryocooler and so on.
