ENGINEERED FOR RUGGED ENVIRONMENTS
What African Power Grids Require
African utility grids predominantly operate at 11 kV and 33 kV distribution voltage classes, with 50 Hz frequency across the continent. Rural electrification programmes and industrial complexes require compact, rugged, ONAN-cooled oil-immersed transformers that can endure continuous high ambient temperatures (+45°C to +55°C) with minimal maintenance.
XinHuan manufactures transformers with corrugated fin tanks that provide maximum heat dissipation surface area, preventing dielectric breakdown in remote substations. Standard vector groups include Dyn11 and Yyn0, with off-circuit tap changers (±2×2.5%) to compensate for fluctuating transmission line voltages.
Export Compliance & Inspection:
Every export batch includes comprehensive Factory Acceptance Test (FAT) reports, third-party inspection (SGS/CCIC), and full documentation for SONCAP (Nigeria) and KEBS PVoC (Kenya) customs clearance.
