China Southern Power Grid Develops China's First 100-Meter High-Current HTS Conductors

China Southern Power Grid (CSG) has successfully developed two 100-meter high-current HTS conductors, based on CORC and TSTC respectively, and the conductors has passed all tests and acceptance checks.

The conductors carried 20 kA at self-field, liquid nitrogen temperature, and 50 kA at 15T, liquid helium temperature. Setting new records in HTS high-current conductor technology for both "maximum length and highest current capacity," this achievement marks a significant success in China's development of large-scale, high-current HTS conductors.

Since 2023, the Electric Power Research Institute of CSG Guangdong Power Grid Corporation has overcome fundamental challenges in the research of HTS magnets, achieving breakthroughs in both the electrical performance and mechanical stability for long-length conductors.

Shanghai Superconductor worked in close collaboration with CSG, supplying all HTS materials required for the project and playing a vital supporting role in the research and development of the sub-cables and conductors.

In the future, Shanghai Superconductor remains committed to advancing HTS technology by providing high-quality materials, backed by our stable production and deep expertise.
