China's Substantive Progress on Superconductor Cable


The 3 — phase AC high   temperature I   superconductor cable project, listed under the

National 863 Program of the Ministry of Science and Technology and supported by the Major S&T Projects Program of the Beijing Municipal Government, has  recently  applauded  its major achievement: a superconductor cable system 4 meters in length and having a current carrier capacity of 2000A completed, installed, and verified at Beijing Yundian Yingna Superconductor Cable Co. Ltd.

This system is the first of its kind in the nation that has been put into successful operation in a complete and closed form. It indicates that Chinese researchers have found solutions to all the key technical difficulties in applying the superconductor cable to practical use. It is predicted that by the end of this year, a set of superconductor cables as long as 30 meters will be installed in the power grid. This will make it the third superconductor power cable in operation in the world following the US and Denmark.
