Abstract

YBCO coated conductor is named by second generation superconductor tapes. It is different with first generation superconductor tapes. YBCO coated conductor's specific difference with Bi-2223/Ag tape is more strong mechanical durability. This is important role to apply to superconducting machines. For mechanical transforming of YBCO coated conductors, we are using the well designed former. The merit of transformation is several. First, we vary the superconducting characteristics according to mechanical stress. Second, we reduce the volume of superconductor, so we achieve reducing the volume of superconducting machines. On this study, we experiment the transporting current characteristics of one types YBCO coated conductor. YBCO coated conductor with Ie of 70 A and voltage grade of 0.6 V/cm were connected to spiral former to conduct current application test.
