# WST has made breakthrough progress in the development of high-temperature superconducting wires

WST announced that recently, the company successfully achieved mass production of practical MgB₂ high-temperature superconducting wire made using powder-in-tube technology, with a single length exceeding 20,000 meters. The company has produced over 250 kilometers of MgB₂ wire, providing technical support as a key material for the superconducting magnetic energy storage device of the Southern Power Grid. At the same time, WST has for the first time in the world prepared kilometer-level multi-core MgB₂ wire using the central magnesium diffusion method
