The world’s first 35 kilovolt superconducting power cable was put into operation in Shanghai on Wednesday, making China among the global leaders in superconducting transmission applications, said its operator, the Shanghai branch of State Grid Corp of China.

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, according to State Grid Shanghai Municipal Electrical Power Co.

Installed in the commercial area of Xuhui district, the 1.2-kilometer cable connects two 220 kV substations with a designed current capacity of 2,200 amps. This is also the first superconducting transmission project built by the centrally administered State Grid in the country.

According to State Grid Corp of China, 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 […]
