Customized MgB₂ Superconducting Wire Toward Practical Applications at Sam Dong in Korea

MgB₂ superconducting wire from Sam Dong Co., Ltd. in Korea is suitable for various applications, including medical resonance imaging, fault current limiters, power cables, and transformers. So far, issues related to the wire production cost, current-carrying capacity, and conductor length (kilometers) are very important for further commercialization. Since 2014, our intensive research efforts have led to notable progress. Herein, we summarize and discuss our advanced research for achieving high-performance, scalable, and cost-effective MgB₂ wires at Sam Dong. Based on our accumulated technical know-how, we will continue to fabricate more competitive and efficient MgB₂ superconducting wires that will be suitable for the customer's purposes.
