SBH15 Series Amorphous Alloy Oil-immersed Transformer – Ultra-Low Loss & Eco-Friendly Power Solution

The SBH15 Series Amorphous Alloy Oil-immersed Transformer sets a new benchmark in energy efficiency for distribution networks. Unlike conventional silicon steel cores, its amorphous metal core reduces no-load losses by up to 70%, making it one of the most eco-friendly and cost-effective solutions for utilities aiming to meet stringent global sustainability targets.

Designed without an oil conservator and featuring a fully sealed corrugated tank, this transformer prevents moisture and oxygen ingress through advanced vacuum oil-filling technology—ensuring long-term dielectric stability and maintenance-free operation. Ideal for urban substations, rural electrification, and green infrastructure projects, the SBH15 series complies with IEC 60076 and supports standard voltages like 10kV/0.4kV with Dyn11 or Yyn0 vector groups.

• Amorphous metal core transformer – dramatically cuts standby energy waste and CO₂ emissions

• Eco-efficient oil-filled unit – engineered for low lifecycle cost and minimal environmental impact

• Sealed low-loss distribution transformer – corrosion-resistant, compact, and built for harsh outdoor conditions

Available from 30kVA to 2500kVA, each unit undergoes rigorous factory testing—including insulation resistance, load loss, and induced voltage withstand—to guarantee reliability. With ultra-low no-load current (as low as 0.4%) and optimized short-circuit impedance, the SBH15 delivers stable performance across fluctuating loads while significantly reducing electricity bills over its 25+ year service life.

Manufactured using 100% copper windings and certified to international standards, this next-generation transformer is a strategic investment for grid operators prioritizing energy savings, regulatory compliance, and long-term operational resilience.
