The Thermal Stability of LTS/HTS Composite Round Wire

摘要

A LTS/HTS composite round wire, made of NbTi/Cu and YBCO was proposed. A 2D heat transfer model has been developed to analyze its thermal stability. Joule heat produced by current transfer was calculated by using the power-law model. The simulation results show that the LTS/HTS composite round wire has instinctive better stability with respect to classical LTS conductor wire.
