Ultra-Low Iron Loss Oriented Silicon Steel B20HS070 for Cold Climate Distribution Transformers

B20HS070 is a grain-oriented silicon steel designed for high-efficiency distribution transformers operating in extremely cold climates. With an ultra-low iron loss of ≤0.65 W/kg and a magnetic permeability retention of ≥95% at -40°C, this material ensures reliable performance in freezing conditions, reducing no-load losses and supporting energy efficiency standards like EU ecodesign.

Key Selling Points

Iron loss ≤0.65 W/kg (P1.7/50) minimizes transformer no-load losses, cutting operational energy costs.
Magnetic permeability retention ≥95% at -40°C ensures stable excitation performance in extreme cold.
Meets EU eco-design requirements for high-efficiency distribution transformers, aiding grid upgrade projects.
Suitable for three-dimensional rolled iron core designs, enhancing energy efficiency and reducing noise.
Proven in Canadian cold-region grid upgrade projects, supporting Class 1 energy-efficient transformers.
