Abstract

Transporting large currents through High-Tc (HTS) current leads (CLs) inevitably involves using several HTS tapes in multi-stacked form to obtain a high current density. For safe operation of HTS CLs, the thermal stability of stacked HTS tapes should be considered. In this paper, we investigated electrical and thermal properties of multi-stacked HTS tapes using 2G coated conductor (CC). Three kinds of commercial CC with different specification of stabilizer were used for the experiment. Each stack sample was fabricated by soldering together CC tapes using In-Bi alloy. To verify the effects of a stabilizer on thermal stability for multi-stacked CC tapes, we performed an experiment of minimum quench energy measurements. In addition, transient electrical and thermal behavior were measured as a function of the external heat input energy. Each stack sample has a heater made of nickel-chromium (Ni-Cr) wire to make the external heat disturbance and a type-E thermocouple to measure the temperature. Based on the test results, electrical and thermal characteristics of multi-stacked CC tapes were evaluated.
