Anhui Jinli warmly congratulates the simultaneous opening of four high-speed railway lines
Great news! Four high-speed railway lines—the Xiong'an-Shangqiu, the Tie'li-Yichun section of the Harbin-Yichun line, the Yixing, and the Xi'an-Ankang—have simultaneously commenced operations, adding four more key corridors to my country's "eight vertical and eight horizontal" high-speed railway network.   Xiong'an-Shangqiu High-Speed Railway | 350 km/h | A key section of the Beijing-Hong Kong High-Speed Railway, opening up a southward corridor from Xiong'an. Harbin-Yichun High-Speed Railway (Harbin–Yichun Section) | 250 km/h | China's northernmost high-speed railway in an extreme cold region Yixing High-speed Railway|350km/h|China Unicom Shanghai-Chongqing-Chongqing and Zhengzhou-Chongqing High-speed Railway Xikang High-speed Railway|350km/h|Crossing the Qinling Mountains and connecting southern Shaanxi The safe operation of high-speed rail relies on stable and reliable power supply and signaling systems. Lightning and transient surges pose major threats to the electrical infrastructure of rail transit; inadequate protection can easily disrupt signals and affect power supply, directly compromising operational safety.   Anhui Jinli Electric’s lightning and surge protection devices (SPDs) have been installed on the four high-speed railway lines mentioned above. Deployed at stations and within supporting power supply facilities along the routes, this equipment continuously withstands induced lightning overvoltages and surge impacts, establishing a robust electrical protection barrier for railway power supply and signaling systems to ensure the smooth, high-speed operation of trains. From the North China Plain to the frigid forests of the Northeast, and from the mountains of western Hubei to the heart of the Qinling Mountains, Jinli Electric’s lightning protection products have proven their reliability across diverse geographical environments and complex climatic conditions. For years, the company has focused deeply on the field of lightning protection for rail transit, continuously refining its surge protection technology to provide comprehensive lightning protection solutions for rail transit and power infrastructure projects both domestically and internationally.   Looking ahead, Anhui Jinli Electric will remain committed to technological innovation and reliable product quality, continuing to support the construction of domestic rail transit projects and safeguarding the safe, stable operation of major transportation arteries.

    Jinli Electric Safeguards the Railway
    Lightning strikes pose a threat to the operation of railway traction substations, often causing equipment damage and power supply interruptions that compromise operational safety. With the advancement of railway intelligence, the limited overvoltage resilience of secondary equipment means that traditional lightning protection methods can no longer meet industry requirements. Railway authorities issued regulatory documents such as *Circular on Transport and Supply Equipment [2017] No. 240* to drive the standardization of railway lightning protection. Aligning with relevant railway technical standards, Anhui Jinli develops customized lightning protection solutions for numerous traction substations. Its proprietary products—including surge protective devices and signal lightning arresters—effectively discharge lightning currents and suppress overvoltage, ensuring the stable operation of on-site monitoring, control, and communication equipment. These products strictly adhere to railway specifications, have been proven effective in real-world thunderstorm conditions, and are widely used across the high-speed rail, electric power, and petrochemical sectors.   For the Guangxi Yucen High-Speed Railway project, Jinli leveraged its technical expertise in railway communication protocols to integrate lightning protection equipment into a unified monitoring platform. This enabled the lightning protection system to be visualized and controlled, reduced the operations and maintenance burden, and achieved a technical upgrade from isolated point-based protection to coordinated system-wide protection. Addressing future railway construction scenarios characterized by high-altitude and heavy-haul operations, Anhui Jinli focuses on on-site requirements to enhance product reliability and intelligence. The company drives the shift from passive lightning protection to active monitoring and early warning, consistently delivering customized, comprehensive lightning protection solutions to safeguard railway transport safety.
