Yongding subsidiary Eastern Superconductor plans to be selected into the "2023 Su-Xi-Chang First (Set) Major Equipment" accreditation list

2023-12-08

Recently, Yongding's wholly-owned subsidiary Eastern Superconducting Technology (Suzhou) Co., Ltd.'s "Superconducting DC Transmission Cable System Equipment Based on Second Generation (YBCO) High Temperature Superconducting Tape (SE-HTSC-DC 10kV/6kA)" was selected as one of the first (set) major equipment in Suzhou and Wuxi in 2023.

In order to speed up the construction of an independent and controllable advanced manufacturing system, promote the high-quality development of the manufacturing industry, and encourage and guide equipment enterprises to carry out technological innovation, Suzhou, Wuxi and Changzhou will jointly organize the identification of the first (set) of major equipment in Suzhou, Wuxi and Changzhou in 2023. After enterprise declaration, regional recommend, form review, material review, on-site verification and other procedures, the "superconducting DC transmission cable system equipment based on the second generation (YBCO) high temperature superconducting tape (SE-HTSC-DC 10kV/6kA)" developed by Eastern Superconducting Technology (Suzhou) Co., Ltd. is to be recognized as one of the high-end equipment with independent intellectual property rights in Suzhou.

The superconducting DC transmission cable in the system equipment (SE-HTSC-DC10kV/6kA) is currently the most compact superconducting cable in China. For the first time, the positive and negative coaxial methods are used to eliminate external electromagnetic interference and make the power system more reliable. At the same time, the superconducting cable uses the second generation of high-temperature superconducting materials developed independently as the coated conductor, which has significant advantages such as high current density, low transmission loss, and environmental friendliness.

The application of DC superconducting transmission technology injects strong impetus into the construction of new power systems and energy transformation and upgrading. In the future, the eastern superconducting will take the first set as the traction, accelerate the construction of independent and controllable high-temperature superconducting advanced manufacturing system, and promote the high-quality development of enterprises.
