Fujian launches pilot application of rare earth aluminum alloy energy-saving cable new materials

According to the bulk non-ferrous net reprinted: Yesterday, the "Straits Construction Forum" jointly organized by the Fujian Provincial Architectural Design and Research Institute and the Fujian Provincial Building Electrical Technology Collaborative Information Network held a forum on quality and safety of rare earth high-speed aluminum alloy energy-saving wire and cable at Fuzhou. At the meeting, leaders and experts of China Electric Power Research Institute, Institute of Metal Research, Chinese Academy of Sciences, Shanghai Cable Research Institute, Wuhan Institute of High Voltage Electrical Appliances, State Grid, Fujian Provincial Housing and Construction Department, Fujian Civil Engineering Society, and other institutions. The new technologies, new materials, new processes and application prospects of rare earth high-speed iron aluminum alloy energy-saving wire and cable have been affirmed and expected.

It is reported that China's rare earth high-speed aluminum alloy energy-saving wire and cable technology in the international advanced level. More than 130 invention patents, such as the preparation method of rare earth high-speed iron aluminum alloy conductors in China, have broken the monopoly of European and American countries in the aluminum alloy cable production technology and market for more than 40 years. The forum conducted an experimental demonstration of the performance of rare earth high-iron iron alloy wire and cable.

Rare-earth high-iron alloys are rare-earth elements added to aluminum, which function to purify, increase purity, fill surface defects, refine grains, reduce segregation, and eliminate microscopic inhomogeneities. According to inspection by authoritative organizations, rare earth high-iron aluminum alloy wire and cable has better safety performance, electrical conductivity, mechanical performance, corrosion resistance, connection performance, economic performance, and better ductility and flexibility than copper and pure aluminum materials. Reductive. This new material weighs only half as much as copper. Participating experts discussed the hot spots of rare earth high-iron iron alloy conductor preparation methods, and conducted special evaluations on the safe use and life cycle economic value of rare earth high-speed iron alloy wires and cables. At present, rare earth high-iron aluminum alloy wire and cable passed the results of failure analysis of the quality capability for a safety life of up to 40 years, and aluminum alloy cable national standards and industrial support policies in the construction field have also been successively introduced.

According to the barometer issued by the National Development and Reform Commission on the completion of energy-saving targets, Fujian Province is the first-level warning in the first quarter of this year. The application of rare earth high-iron alloy wire and cable will promote the healthy development of the infrastructure of our province and the realization of energy-saving and emission reduction targets. The advantages of longer service life of rare earth high-speed rail aluminum alloy cables, composite utilization of better colored resources, and lower procurement costs have been highlighted. According to experts, the comprehensive cost of rare earth high-speed iron alloy wire and cable is 20% lower than that of copper material, 15% of the cost per kilometer line is reduced, and 2~3% of line loss is reduced. This new material is popularized and applied every year. The province will achieve more than 20 billion yuan in energy-saving emission reduction benefits.

Fujian’s Free Trade Pilot Zone has been formally approved by the State Council. Our province will usher in the favorable conditions of pioneering, striving for superiority and scientific development, practicing the law of economic development, giving priority to science and technology, and guaranteeing the development of qualified personnel, and improving the construction technology industry. The development is of great significance. The national standard for rare earth high-iron aluminum alloy energy-saving wire and cable has been formulated. The forum also studied the "GB/T29920-2013 high-iron rare earth alloy rod for electrical use", "GB/T30552-2014 aluminum conductor for cable conductor", "DB34/T1284.1-2010 rare earth high-iron aluminum alloy environmental power Cable and some national standards and local standards in Fujian province discussed and issued the draft guidelines for the "Guidelines for Safety Design Acceptance of Rare Earth High-speed Rail Aluminum Alloy Cable Products for Safeguarding Consumer Rights and Interests" of the Ministry of Housing and Urban-Rural Development of Fujian Province.

It is understood that, as a participant in the formulation of national standards for rare earth high-speed rail aluminum alloy energy-saving wire and cable, Xinyi Cable Group announced in this forum that it will launch pilot projects for the promotion and application of infrastructure construction in Fujian to help promote the application of new infrastructure and new materials in Fujian. The work will contribute to the country’s “all the way” and the construction of the Fujian Free Trade Zone.
