Guangdong Yudean Huila Powe Plant Unit 5 and 6 Expansion

Coastal power plants globally face the critical challenge of salt-spray corrosion (which degrades standard cables in 2–3 years, per IEC 60092-350’s marine environment guidelines)—a risk amplified for hubs like the Pearl River Delta (PRD), China’s industrial heartland (supporting 12% of the nation’s manufacturing output). The 2*1000MW expansion of Guangdong Yudean Huilai Power Plant (commissioned 2024) aimed to add 18 billion kWh annual capacity (powering 4 million PRD households and 2,000+ industrial firms), requiring cables resilient to the region’s 80% annual humidity and salt-laden coastal air.

Anhui Jinhong addressed this with marine-grade CSPE-sheathed cables (compliant with IEC 60092-350, tested to resist salt-spray corrosion for 15+ years—5x longer than standard PVC-sheathed cables). It also supplied high-efficiency low-loss power cables (reducing transmission waste by 6%, aligning with the IEA’s global power infrastructure efficiency targets) and fire-resistant boiler cables (meeting IEC 60332-3 for 3-hour heat resistance). To meet the plant’s 24-month construction timeline, Jinhong ramped up production by 30%, delivering 200km of custom-spec cables in phased batches synchronized with the plant’s equipment installation.

Since operations began, the units have run at 98% capacity, eliminating summer power shortages that previously forced PRD textile mills to cut production by 15%. Maintenance inspections in 2025 found zero corrosion on Jinhong’s cables (vs. 20% degradation in standard cables used in the plant’s older units), proving the solution’s alignment with global coastal power infrastructure durability standards. This success secured Jinhong a 3-year framework agreement with Yudean Group, expanding its footprint in coastal energy cable solutions—a sector critical for 30% of global power plants located near coastlines.
