Anyang High-Speed Railway Transportation

As global high-speed rail (HSR) networks expand (projected to reach 70,000km by 2030 per the International Union of Railways, UIC), traction cable resilience, electromagnetic compatibility (EMC), and critical power reliability have become non-negotiable standards—defined by IEC 62278 (railway application safety) and UIC 552 for HSR infrastructure. The 25km Anyang section of the Beijing-Guangzhou HSR (commissioned 2024) was designed to cut travel time between Anyang and Beijing to 2 hours, serving 10,000 daily passengers (including Spring Festival peak volumes), and required cables that could withstand 300km/h train vibrations, 27.5kV traction loads, and zero signal interference for train control systems.

Anhui Jinhong tailored solutions to these global HSR benchmarks: it supplied EPR-insulated 27.5kV traction cables (tested to 10 million vibration cycles, exceeding IEC 60811-2-1’s durability requirements), double-shielded signal cables (meeting IEC 61000-4 EMC Class B to eliminate disruptions to ATP (Automatic Train Protection) systems), and low-smoke zero-halogen (LSZH) fire-resistant emergency cables (complying with IEC 60332-3 for 3-hour fire survival, critical for passenger evacuation routes). A key challenge was aligning cable installation with the HSR’s 12-month upgrade timeline; Jinhong deployed a mobile production unit to deliver custom-length cables on-site, cutting lead times by 20%.

Post-commissioning, the section maintained a 100% on-time operation rate during the 2024 Spring Festival (when passenger volumes surged 40% above baseline), with stable traction power even under peak load. The reliable cable infrastructure supported a 40% increase in Anyang’s annual tourist arrivals (as faster connectivity boosted regional tourism), aligning with global HSR’s role in driving economic regionalization. This project solidified Jinhong’s position in global HSR cable solutions—a sector growing 9% annually as nations prioritize intercity connectivity.
