This study is about the cooling of the superconducting wire by spraying the liquid nitrogen. In this study, the superconducting wire was cooled under the spray cooling condition, and a current flow test was conducted. In addition, the operating range of the superconducting wire was presented under the spray cooling condition of the liquid nitrogen. For this, a low temperature container with a spraying device was fabricated, and the cooling performance of the container was evaluated. The YBCO superconducting wire for the spray cooling test had the Bi-2223/Ag superconducting wire and stainless
steel wire as stabilizer layers. The wires were the representative superconducting wires that were fabricated using the PIT and sputtering techniques. The current flow test was conducted in the normal and over current conditions, and the results were compared with those of the existing immersion cooling method.
