Shanghai Superconductor answers first IPO review round, citing tape current on par with leading rivals

Shanghai Superconductor Technology/2G REBCO superconducting tape

Shanghai Superconductor published its replies to the exchange's first round of IPO questions, including a comparison with rival tape. At 77 K with no field its tape carries 110-250 A, above SuperPower's 80-160 A and in line with Faraday Factory Japan and Eastern Superconductor. In a strong field at 4.2 K its top figure sits below Faraday Factory Japan's 900 A and SuperPower's best.

• At 4.2 K in a 10 T field: 350-800 A.
• Tensile strength 600-700 MPa; product yield above 90%.
• Each core production machine makes about 16 km a month; 2024 capacity was 1,334 km.
