First 100-Meter-Long Superconducting Tape Debuts in China
China has produced its firstbi-base superconducting tape longer than 100 meters, which will bring revolutionary changes to the country's energy industry, the Beijing Non-Ferrous Metal Research Institute announced November 26.��
The development signifies that the country's research and development program in superconducting materials has developed into industrial use, said Yuan Guansen, a researcher with the institute.��
"The new technology will dramatically reduce losses in electricity transmission from 20 percent to almost nothing," he said.��
In July 1998, the institute produced its first one-meter-long bi-base 1000 ampere superconducting tape. The new tape is 116 meters long, 3.6 mm wide, 0.28 mm thick and meets advanced international standards.��
According to Yuan, if the length of superconductive tape exceeds 100 meters, it can be put into industrial use, for electricity transmission cables, electricity voltage transformers and MRI technologies.��
The United States, Japan and European countries are leading the research and development of superconductive materials, but China is catching up fast, Yuan said.��
