2, Bailey Electric-600468, popularity leader, superconducting current limiter project for the smart grid construction of superconducting current limiter there is a huge demand, the company intends to set up a joint venture with the Beijing YunDian YingNa Bailey YunDian engaged in the superconducting current limiter R & D and production, and will be built to become the most leading superconducting current limiter design, development, production enterprise. 2012 In December 2012, 220kV/800A high-temperature superconducting current limiter completed 72 hours of network operation inspection, and officially entered into network operation at the 220kV substation of Shigezhuang of State Grid Tianjin Power Company.
3, Zhongfu industry-600595, popularity leader + performance leader, the company undertook the national "863" program in the field of new materials key issues. The company's official website disclosed that in April 2013, by the Chinese Academy of Sciences Institute of Electrical Engineering and in the Fu industry jointly developed a length of 360 meters, the current-carrying capacity of 10 kiloamps of high-temperature superconducting DC transmission cable in the Fu industry through the Ministry of Science and Technology of the State Organization of the expert technical acceptance for the design of China's high-temperature superconducting cable, manufacturing and operation of the accumulation of valuable experience. The cable is currently the world's largest high-temperature superconducting cable transmission current, but also the world's first high-temperature superconducting DC cable to realize grid-connected demonstration operation, marking another breakthrough in the development of large-capacity superconducting cables in China, and is in a leading position in the international arena, and has also been highly valued by the industry's leading academics.
