On November 26, we learned from China's ultrafine-grain strengthened copper-magnesium alloy contact wire manufacturer JSKY. After the review by the Chinese Academy of Engineering Academician Huang Chongqi and other authoritative experts in the industry, the company developed high-performance copper-magnesium alloy strands for electrified railways, etc. The conductivity of the three new products has been further increased by 10% -15%, which can reach 95% IACS. The product technology is reliable, the production efficiency is significantly improved, and it has extremely high value for promotion and use, so as to achieve green energy saving.
On July 17, 2009, JSKY developed the ultra-fine-grain reinforced copper-magnesium alloy contact wire for high-speed rail successfully released, marking the complete localization of the main material of China's high-speed rail contact net. Over the past ten years, the catenary wire used in various geological environments at 200-350 hrs has formed a patent group composed of dozens of patents, which has kept China leading the world in the field of high-speed catenary wire.
JSKY has accumulatively obtained 75 national patents on R & D and production of high-speed rail contact wire, including 10 invention patents, among which 9 newly-invented invention patents and 13 utility model patents are under examination and approval. After ten years of hard work, Kangyuan will continue to follow the “Belt and Road” initiative and China's high-speed rail “going out” national strategy.
