SuperPower正在开发一种导体设计，以改善机械性能、淬火稳定性和低交流损耗。涂覆导体通常为12毫米宽，上面有几微米的银层。SuperPower的设计将这种基导体设计修改为更适合实际应用的几何形状。宽导体被切成4毫米宽的胶带，特别是用于电缆应用，但也可以减少交流损耗。切割后，导体周围约有20微米的铜稳定剂，完全封装导体并提供密封。环绕铜稳定器配置的其他优点是圆形边缘，用于介质集成和卓越的过电流处理能力（9X临界电流，300 ms宽脉冲）。住友电气使用这种实用导体制作的1米电缆的原型显示，总交流损耗低于0.4 W/kA‐m。为了进一步减少交流损耗，特别是在军事高频应用中，SuperP…
SuperPower is developing a conductor design for improved mechanical properties, quench stability, and low ac losses. Coated conductors are typically 12 mm wide with a few microns of silver overlayer. SuperPower’s design modifies such base conductor designs into geometries more suited for practical applications. Wide conductors are slit into 4 mm wide tapes, in particular for cable applications, but also to reduce ac losses. After slitting, the conductor is stabilized with approximately 20 microns of surround copper stabilizer, completely encapsulating the conductor and providing a hermetic seal. Other advantages of the surround copper stabilizer configuration are rounded edges for dielectric integration and superior over‐current handling capability (9X critical current with 300 ms wide pulses). Prototype 1 m cables made by Sumitomo Electric using this practical conductor showed total ac losses under 0.4 W/kA‐m. To further reduce ac losses, especially for high frequency applications of the military, SuperP...
