"According to foreign market bidding information in 2011, the number of tenders in the main developing countries is tens of thousands of tons, all aluminum alloy wire (AAAC) bidding over 60 thousand km, aluminum alloy core aluminum strand (ACAR) bidding over 40 thousand km... "According to the bidding information of the domestic market in recent years, the number of bidding for alloyed conductors has shown a rapid upward trend and is expected to reach 300,000 tons by 2015." You Weiren, director of Zhongtian Science and Technology Wire Research Institute and chief engineer of Shanghai Zhongtian Aluminum Wire Co., Ltd., said at the Asia High-end Wire and Cable Summit in 2012.

      He has been engaged in the development and process management of wire and cable for a long time. It has a deep study on the aluminum alloy used on overhead transmission lines. The report of "the application of aluminum alloy products on overhead transmission lines" is a centralized introduction and long-term prospect for his research project.

     At present, "aluminum alloy is widely used in China's power transmission lines in the form of steel core heat-resistant aluminum alloy strand, all aluminum alloy strand and aluminum alloy core stranded wire." Compared with the traditional copper core cable, the aluminum alloy wire has the advantages of saving energy and saving energy. Compared with the steel core wire, it has the advantages of small wire diameter, increasing conductive interface and reducing transmission loss. The prospect of application is very wide. 

     The report "Application of Aluminum Alloy Products on Overhead Transmission Lines" aroused the strong interest of the participants and had in-depth exchanges and interactions with Mr. You Weiren. 

     The Summit was hosted by Intelligent Research Consultants in London. It was held in Shanghai on the morning of November 27 and ended in the afternoon of November 28. The agenda lasted two days. It has attracted more than 100 experts, general workers, chairman and general manager from China, Japan, South Korea, Indonesia and other Asian cable countries.
