Lightning is a major natural disaster threat to railway traction power supply systems. As the core power supply point for high-speed and electrified railways, traction substations are directly threatened by lightning strikes, which can cause equipment damage and power outages. With the increasing intelligence of railways, secondary electronic equipment is becoming more sensitive to overvoltages, and traditional protection solutions are no longer sufficient to meet the high standards required by projects.

Domestic railway authorities have issued regulations such as the Letter on Equipment Supply and Transportation [2017] No. 240, clarifying the technical standards for lightning protection equipment in traction substations and promoting the standardization and systematization of railway lightning protection. As a professional supplier of secondary lightning protection equipment, Anhui Jinli strictly adheres to industry standards, providing complete lightning protection solutions for numerous traction substations.

The company independently develops surge protectors, signal surge protectors, and integrated intelligent surge shields, which can efficiently discharge lightning current, suppress system overvoltage, and protect the stable operation of substation measurement, control, protection, and communication equipment. The products follow railway technical standards throughout the entire process, are seamlessly compatible with traction power supply systems, and their delivery reliability has been verified on-site during multiple rainy seasons. They are now widely used in high-speed rail, power, petrochemical, and other industries.

In the Guangxi Yucen High-speed Railway project (a key railway project in the Guangdong-Hong Kong-Macao Greater Bay Area), Anhui Jinli implemented an intelligent lightning protection system. Lightning protection devices are no longer independent protection units; their operational status is integrated into a unified monitoring platform, enabling the lightning protection system to be visualized and monitored. This effectively reduces on-site maintenance pressure and completes the upgrade from passive lightning protection to comprehensive collaborative protection.

Facing the complex railway projects of the future, such as those in high-altitude and heavy-haul areas, Anhui Jinli will continue to iterate the reliability, compatibility, and intelligent monitoring capabilities of its lightning protection products, promote the upgrading of railway lightning protection towards proactive early warning, provide customized overall lightning protection solutions for global railway projects, and build a solid safety barrier for rail transit power supply.
