Customization Power Transformer for Industrial Power System-220kV

50MVA oil-immersed power transformer is engineered for 161kV/170kV/220kV transmission substations, stepping down high-voltage power to medium-voltage levels (110kV/35kV) for industrial zones, urban centers, and large-scale infrastructure. Featuring low-loss silicon steel cores and optimized copper windings, it reduces energy losses by 15–20% over long-distance transmission (50–200km).

Equipped with on-load tap changers, pressure relief valves, and gas relay protection, it ensures stable grid interconnection and fault-safe operation in extreme environments from −30°C to +45°C. Fully compliant with IEC 60076-1, IEEE C57.12.00, ANSI C57.12.90 and AS/NZS 60076.5.
