NPC Deputy Tang Liang: It is recommended that the state carry out the national layout of the superconducting cable network as soon as possible

At this year's National Two Sessions, Tang Liang, deputy to the National People's Congress and chairman of Aosheng Group, will make suggestions
on the transformation of scientific and technological innovation achievements.
Tang Liang said that a proposal I submitted this year is to accelerate the promotion of high-temperature superconducting technology and promote the industrialization and marketization
of China's superconducting technology.

Tang Liang believes that real scientific and technological innovation consists of two parts: one is the independent research and development breakthrough of new materials and new technologies, and this 'breakthrough' must have the world's first scientific and technological content; second, after new materials and new technologies are transformed into high-tech new products, they must be applied and promoted
.
If there is no closely followed landing and promotion, the industrialization and marketization of new products cannot be discussed
.

For example, he said that last year, the world's first 35 kV kilometer-level high-temperature superconducting cable demonstration project was officially put into operation in Shanghai, achieving a systematic breakthrough in key core technologies, and many indicators reached the world's first
.
This is a landmark achievement
of firmly grasping the scientific and technological innovation of cutting-edge new materials, "fighting" with advanced countries in the world for new high-temperature superconducting materials and new scientific and technological runways, and leading the world's high-temperature superconducting technology.

Tang Liang mentioned that although China has made the world's first breakthrough, it must not relax and continue to maintain the momentum of "leading", because many countries are also catching up
.
Since this new technology has shown a wide range of application scenarios in the fields of urban power, high-end medical equipment, maglev transportation, rail transit and large scientific devices, the commercialization process is accelerating
.

"China should also step up the promotion of high-temperature superconducting transmission technology
.
" Only by landing and promoting can we continuously improve the scientific and technological content in practical applications and always maintain a global leading position
in this technical field.
Tang Liang said
.
To this end, the content of his proposal at this year's two sessions is to accelerate the promotion of high-temperature superconducting technology and promote the industrialization and marketization
of China's superconducting technology.

He suggested that the State Grid promote the construction project of the 5-kilometer-level superconducting cable transmission demonstration project as soon as possible according to the needs of the development of Shanghai, a super-large central city, to meet the long-distance transmission requirements of 35 kV cables and solve the problem
of large-capacity centralized power transmission in China's central urban areas.
It is suggested that during the "14th Five-Year Plan" period, State Grid will first comprehensively promote the construction
of high-temperature superconducting cable projects in areas with dense population, concentrated large cities and increased electricity load in the Yangtze River Delta.

It is recommended that the state carry out the national layout of the superconducting cable network as soon as possible, and gradually build a multi-voltage superconducting cable network in large and medium-sized cities across the country to replace the structure
of the existing traditional power grid.
Accelerate the application of superconducting cable transmission technology in urban rail transit construction to better meet the needs of
economic and social development.
It is suggested that through the promotion of superconducting cable transmission technology, the proportion of electric furnace smelting capacity in China will be effectively implemented from the current 10% to 15% by 2025, and strive to achieve the national strategic goal of 20%, significantly reduce carbon emissions in the steel industry, and provide strong support
for the realization of China's "dual carbon goals".
