I will introduce the activity of RE-123 Coated Conductor (CC) at Shanghai Superconductor Technology Co. Ltd (SSTC). Recently we have many HTS projects in China including accelerator, high-field magnet, electric power applications and so on. For these projects, we have been supplying a large amount of RE-123 CC stably. The CC fabrication process is PLD-IBAD method and the Ic (77K, 0T) is around 400 to 500A/cm. Each process is done at a high speed around 100 m/h. Now, we can supply a large amount more than 100km/year. Together with the Chinese HTS project, these R&D activities including Ic improvement at high filed and low temperature, mechanical property, junction and combined conductor will be presented.
