Innovative Applications of Electrical Steel in Transformers – Driving Energy Efficiency and a Green Energy Future

As the global energy landscape shifts toward decarbonization and digitalization, transformers—the backbone of power transmission and distribution—play a pivotal role in grid reliability and sustainability. Electrical steel (silicon steel), with its ultra-low core loss and high magnetic permeability, serves as the core material for transformer cores, enabling higher efficiency and reduced energy waste. As a global leader in electrical steel innovation, we empower transformer manufacturers with advanced material solutions to build smarter, greener power networks.

Electrical Steel: The "Energy Heart" of Efficient Transformers

The transformer core is central to energy conversion, and the magnetic properties of electrical steel directly determine no-load losses (core losses), noise levels, and thermal performance. Our electrical steel delivers transformative benefits:

Ultra-Low No-Load Losses

1.High-permeability grain-oriented electrical steel (e.g., 30Q120, 27QG100) achieves core losses as low as 0.90W/kg@1.7T/50Hz, reducing no-load losses by 20%-30% compared to conventional materials. This ensures compliance with IEC 60076, IEEE C57.12.00, and other global efficiency standards.

2.Reduced energy loss translates to long-term cost savings for grid operators, particularly in 24/7 high-load scenarios like renewable energy integration and data centers.

Quiet Operation & Enhanced Durability

1.Advanced domain refinement technologies (e.g., laser scribing, mechanical scratching) minimize magnetostriction, lowering operational noise to <45dB for urban substations and residential areas.

2.Specialty insulation coatings (e.g., C5, C6) provide corrosion resistance and thermal stability (≤150°C), ensuring reliability in harsh environments (high humidity, altitude).

Technological Breakthroughs: Solutions for Modern Power Systems

To address smart grids, renewable integration, and digital substations, we innovate relentlessly:

High-Frequency & High-Power Density

Ultra-thin grain-oriented steel (0.18mm-0.23mm) with core losses ≤1.20W/kg@1.5T/1kHz supports high-frequency transformers (e.g., solar inverters, EV charging stations), compatible with SiC/GaN devices for superior efficiency.

Sustainable Manufacturing

Hydrogen annealing processes reduce carbon emissions, while chrome-free coatings comply with EU RoHS and REACH regulations.

Smart Design Integration

Multi-physics simulation platforms (magnetic-thermal-mechanical) optimize core lamination and cutting processes, balancing efficiency and cost.

End-to-End Application Coverage

Our electrical steel powers transformers across industries:

Power Transformers

Oil-Immersed: Ultra-high-voltage cores (≥500kV)

Dry-Type: High-efficiency models (e.g., SCB13/SCB18)

Renewable Energy

1.Solar inverter transformers, wind power compact substations

2.Bi-directional DC-AC converters for energy storage systems

Industrial & Specialty Use

1.Arc furnace transformers, traction transformers (high-speed rail/metro)

2.High-frequency transformers (data center UPS, medical equipment)

Pioneering a Zero-Carbon Grid Ecosystem

Under the global net-zero mandate, high-efficiency transformers are critical for grid modernization. We empower clients to develop ultra-low-loss, smart transformers that accelerate the clean energy transition.
