CHANGFENG GROUP.CHANGFENG GROUP was established in 1996 with registered capital of RMB 600 million. As a national high-tech enterprise, it has developed into a comprehensive economic entity integrating production, sales, and R&D. As a Chinese manufacturer of 6-35kV aluminum alloy cables, the company adopted American aluminum alloy cable production technology. Its conductors utilize special-shaped conductor compaction technology, achieving a compaction coefficient of 0.94—significantly higher than the domestic standard of 0.9. This technology leads the domestic industry. In October 2015, the company obtained UL certification in the United States, covering four standard products and 11 product systems. In 2011, it independently developed mineral-insulated flexible fire-resistant cables, becoming China's first producer of aluminum alloy fire-resistant cables and securing 12 national patents. CHANGFENG GROUP implements a standardized, proceduralized management system for its production processes and quality supervision. Primary products include: High/low-voltage power cables Overhead cables Tunnel boring machine cables Mineral-insulated flexible fire-resistant cables Radiation-crosslinked cables Aluminum stranded conductors with steel core Rubber-sheathed cables Various low-smoke zero-halogen, low-smoke low-halogen, flame-retardant, and fire-resistant wires and cables Control cables Polyvinyl chloride (PVC) insulated wires and cables
