en.Wedoany.com Reported - XD Optical Cable, a subsidiary of China XD Electric Group, has achieved its first supply breakthrough in the CR450 high-speed railway cable sector. Its independently developed ultra-high-strength copper-magnesium alloy contact wire product, designed for high-speed railways operating at 450 km/h, successfully won the bid for the main line contact wire supporting project on the Chengdu-Chongqing Middle Line section. The company secured key project orders for both the Sichuan section and the Chongqing section of the newly built Chengdu-Chongqing Middle Line Railway (including Shiling South Station). This bid represents a significant advancement for XD Optical Cable in the Southwest China railway infrastructure market and marks the productized application of the enterprise's core technology in high-speed railway contact wires.

The Chengdu-Chongqing Middle Line High-Speed Railway is a core project of China's "Eight Vertical and Eight Horizontal" high-speed railway network and a key segment of the Shanghai-Chongqing-Chengdu High-Speed Railway along the Yangtze River. The line has a total length of 292 kilometers, with the Jianyang-Dazu section being China's first benchmark high-speed railway operating at a speed of 400 km/h. This section will undertake core test tasks for the CR450 EMU (Electric Multiple Unit) assessment and finalization, with technical standards and construction specifications at the world's leading level. The ultra-high-strength copper-magnesium alloy contact wire that won the bid is a core product adapted for high-speed railways at the 450 km/h speed class. Its technology and product performance meet the project's requirements for ultra-high speed and high-standard construction. After the project is operational, it is expected to significantly enhance the synergy between Chengdu and Chongqing, effectively improving the coordinated development and opening-up capacity of the western region.

This successful bid not only consolidates XD Optical Cable's advantageous position in the high-speed railway contact wire field but also drives a leapfrog upgrade in the enterprise's high-speed railway cable business, further strengthening its leading position in China's domestic railway cable sector. At the same time, it lays a solid foundation for the company to deepen its presence in the Southwest China market and the core track of urban rail transit.

In the next step, XD Optical Cable will seize the strategic opportunity of building the Chengdu-Chongqing Dual-City Economic Circle, fully implement the company's strategic deployment, and continue to deeply cultivate the core track of rail transit and key markets in Southwest China. It will adhere to technological innovation and deepen its efforts in the R&D of high-end cables. Looking to the future, China XD Electric Group will create benchmark projects with high-quality self-developed products, professional services, and refined contract execution, continuously empowering the construction of a strong transportation nation and contributing XD's strength to the high-quality development of national electrical equipment.
