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.
