Selection and attention of heat resistant aluminum alloy conductor (NRLH60GJ)
Since the 16th National Congress of the Communist Party of China, China's electric power technology has achieved a new leap. Among them, the technology of large cross-section conductor and heat-resistant conductor to improve the thermal capacity and transmission capacity of the line is listed as one of the important achievements in the development of power grid technology.
China is studying and applying 1000kV AC UHV and ± 800kV DC UHV transmission technology. The northwest 750kV Transmission and transformation pilot demonstration project, which was put into operation in September 2005, is the AC transmission and transformation project with the highest operating voltage level in China, laying a good foundation for the development of megavolt UHV technology in China. China has drafted the technical specifications for the million volt power transmission and transformation equipment, and the power transmission and transformation equipment manufacturing enterprises and research institutions have the conditions and foundation to develop the million volt power transmission and transformation equipment, and the UHV test base is under construction. Our country has the ability to design, manufacture, construct and operate the UHVDC transmission project.
Long transmission distance and large transmission scale are the main characteristics in the development of China's power grid. In order to improve the transmission capacity of power grid, China is constantly strengthening the research on the calculation and analysis theory of power system, the stability control of power grid, the application of advanced and practical transmission technology, and the enhancement of management and equipment transformation and capacity increase. At present, a series of research results have been achieved.
