SZ-12500-37
The 37kV power transformer SZ-12500-37 is a high-capacity 12.5MVA electrical solution engineered for precision voltage conversion in industrial and utility grid systems. Compliant with global IEC 60076 and IEEE C57.12 standards, this step-down transformer features a low-loss grain-oriented silicon steel core with no-load loss ≤18kW and an efficiency rating exceeding 99.1%, delivering ultra-low energy waste for large-scale power users. Equipped with dual ONAN/ONAF cooling technology, it operates stably in extreme temperatures from -30°C to +45°C, with a 6.5% short-circuit impedance that bolsters grid stability even under high-load conditions. Designed for a 35+ year lifespan, the SZ-12500-37 transformer offers customizable secondary voltage configurations, making it a versatile core component for industrial plants, distribution substations and heavy-duty power infrastructure worldwide.
Advanced silicon steel core technology cuts no-load losses to 18kW max, driving 10% lower operating costs than industry benchmarks and supporting sustainable energy management for industrial operators.
Integrated OLTC (On-Load Tap Changer) with ±2×2.5% tapping range ensures real-time voltage adjustment, eliminating downtime for tap changes and maintaining consistent power supply for high-precision industrial equipment.
Dual cooling systems and reinforced tank construction enable operation in harsh conditions, with a 65K winding temperature rise tolerance and resistance to vibration, dust and corrosive air.
35+ year design life reduces capital expenditure for replacement and maintenance, with optional DGA (Dissolved Gas Analysis) monitoring for predictive fault detection and minimized unplanned downtime.
