With the continuous expansion of production capacity by automakers like BYD, Nio, and Volkswagen (Anhui) in Hefei, a supporting industry cluster specializing in new energy vehicle high-voltage wiring harnesses is taking shape. This month, three more renowned harness manufacturers from the Yangtze River Delta and Pearl River Delta regions signed agreements to settle in Hefei's component industrial park, with a total investment exceeding RMB 1.5 billion. The new factories will introduce fully automated high-voltage wiring harness production lines, achieving real-time synchronization with OEM production schedules. By the end of 2026, Hefei is expected to form a local supply capacity of 2 million sets of vehicle high-voltage wiring harnesses annually, reducing the supply chain radius to within 50 kilometers
