YBCO涂层导体长带将逐步应用于各种强电领域,如电缆、变压器、超导电机等。YBCO带材在应用过程中,不可避免会受到各种机械应力的作用,这些应力很可能会对YBCO涂层导体的临界电流密度、交流损耗等物理性能产生影响,从而限制其实际工程应用。日本Yokohama大学的科研人员, YBCO coated conductor strip will be gradually applied to a variety of areas of strong electricity, such as cables, transformers, superconducting motors and so on. YBCO tape in the application process, will inevitably be subjected to a variety of mechanical stress, these stresses are likely to YBCO coated conductor critical current density, AC loss and other physical properties have an impact, thereby limiting its practical engineering applications.
