China, Shanghai: The world’s first 35 kV superconducting power cable was put into operation in Shanghai.
This has listed China among the global leaders in superconducting transmission applications.
The high-capacity superconducting power line, which is, so far, the world’s longest superconducting cable transmission project with the largest transmission capacity, marks a major breakthrough in core technologies of China’s construction of a new power system.
Installed in the commercial area of Xuhui district, the 1.2 km cable connects two 220 kV substations with a designed current capacity of 2,200 A. This is also the first superconducting transmission project built by the centrally administered State Grid in the country.
The nation’s largest power provider by generating capacity, the superconducting cables-one of the most revolutionary cutting-edge technologies in the power sector-represent an innovative power transfer technology that has the potential to offer numerous benefits.
“The transmission capacity of superconducting cables is much greater than that for conventional cables, but with much less transmission loss. It is also very suitable for power supply in high-load density areas, providing a new solution to the problem of power supply in high-load-density areas of megacities,” says Xie Wei, Chief Engineer, State Grid Shanghai Municipal Electrical Power Co.
