The transmission capacity of China's power grid is insufficient. In the expansion and transformation of transmission lines, how can we “never save air corridors and increase transmission capacity� Shanghai Zhongtian Aluminum Wire Co., Ltd. has found a solution and its research and development of heat-resistant aluminum alloy wire won the bid for the Beijing Olympics and other projects. Industry insiders believe that the heat-resistant aluminum alloy wire developed by Zhongtian Aluminum has brought about a power transmission revolution. It is reported that the adoption of heat-resistant aluminum alloy wire for power grid reconstruction basically eliminates the need to requisition land for the replacement of towers, so that it can meet the requirements for increasing transmission capacity and increase the transmission capacity of existing lines by 40% to 60%. This not only reduces project investment, but also saves energy. The land resources needed to build the tower. Because of this, the 60% IACS heat-resistant aluminum alloy wire of Zhongtian Aluminum was awarded twice in the Beijing Olympics. As a production base for special wires, Shanghai Zhongtian Aluminum Wire Co., Ltd., after several years of efforts, combined with the needs of the domestic and foreign power markets, has developed a variety of special conductors to meet market demand. At present, 60% IACS heat-resistant Aluminum alloy wire, high-strength aluminum alloy wire, large-length aluminum-clad steel wire, high-strength heat-resistant aluminum alloy wire and other products have been widely used in domestic and foreign power markets, and are widely praised by users.
