Recently, the domestic first ±375V/4500A 100-meter positive and negative coaxial cold insulated high-temperature superconducting DC cable demonstration project jointly implemented by China State Grid JS Power Co., Ltd. and JSYD Superconducting Technology Corporation. It has successfully passed the type test of an authoritative third-party testing agency, which marks a key step in the country's first "Cold Insulation High-Temperature Superconducting DC Cable Demonstration Project" and is a milestone.
Committed to promoting energy reform and development, building a new power system with new energy as the main body, China has built a national key research and development plan "Key Technologies and Applications of Low-voltage DC Power Distribution and Power Systems" demonstration project, and the application of high-temperature superconducting DC power transmission technology has been included. Important content of the demonstration project.
As a well-known professional group of second-generation high-temperature superconducting materials and superconducting electrical equipment at home and abroad, JSYD's high-temperature superconducting tape technology is industry-leading, and has begun to deploy a new kilometer-scale second-generation high-temperature superconducting (2G-HTS) tape. Industrialization of materials and research and development of related application technologies.
In the fields of superconducting power transmission technology, JSYD has maintained a long-term and in-depth cooperative relationship with the State Grid Corporation of China.
It is reported that the superconducting DC cable demonstration project is scheduled to be completed and put into operation in the second half of 2022. At that time, JSYD will fully grasp the key technologies of positive and negative coaxial high-temperature superconducting DC cables from feasibility research, design, manufacturing, testing, laying, operation and maintenance, evaluation, etc., and fully demonstrate the zero transmission loss of superconducting DC cables. characteristics, strengthen the strategic transformation of new energy, and promote innovative power transmission construction and energy industry upgrading.
