Description

technical field [0001] The invention relates to a high-strength and low-loss cable conductor material, a preparation method and application thereof, and belongs to the technical field of electric cable conductor materials. Background technique [0002] With the rapid development of railway electrification in my country since the 1960s, the speed of railway transportation has been increased again and again, and the highest speed of high-speed railways has continued to refresh records. Performance, but also high tensile properties. Compared with foreign countries, my country's research and development of power cable conductors started relatively late, and the research and development and manufacturing technologies are still immature. With the increase of power transmission threads, new requirements are put forward for the strength of power cable conductor materials, and it is urgent to improve the strength of current power cable conductor materials to meet the needs of long-di...
