Development of HTS BSCCO wire for power applications

摘要

As the first company engaged in commercial manufacture of HTS BSCCO wires in China, Innost has devoted great efforts to improve the electrical performances and practical properties of its HTS wire products. Based on huge amount of fundamental research work, the short sample can achieve 120 A of I/sub c/ and 12 kA/cm/sup 2/ of J/sub e/. Under strict quality control, Innost's HTS wire can be manufactured reproducibly with length up to 1 km, I/sub c/ over 90 A and J/sub e/ over 9 kA/cm/sup 2/. Meanwhile, to demonstrate technical feasibility and reliability of HTS power apparatus, diversified wire-design has been carried out, including reducing AC losses and thermal conductivity, increasing insulating properties and mechanical strength, and so on. Up to now, Innost's diversified wire products have been widely used in domestic and international R&D projects of HTS application.
