The Glow Rod Factory completed the process debugging and achieved mass production; the Fiber Factory maintained the maximum scale production, improved the drawing speed, optimized the quality, and stabilized the position of the fiber market; the Cable Factory developed new special cables and other new products, and optimized the product structure.
The "High Temperature Superconducting DC Cable Demonstration Project" jointly implemented by the company and Jiangsu State Grid will be put into operation in the second half of 2023. This project is the first superconducting cable in Jiangsu Province and the first cold-insulated high-temperature superconducting DC cable based on the second-generation (YBCO) high-temperature superconducting material in China. The designed DC load capacity of the cable can reach 100MW, which fully reflects the characteristics and advantages of low voltage, large current and high capacity of superconducting DC cables.
