1. The Critical Role of CRGO in Power Grids
The global energy transition demands higher efficiency. The Transformer Core, being the heart of the electrical induction process, determines the base-load loss of any power system. Using premium Cold Rolled Grain Oriented (CRGO) steel is no longer optional—it is a regulatory necessity.
2. Technical Specifications: Material & Design
To meet international standards like IEC 60076 and IEEE C57, we focus on three technical pillars:
- Material Selection: Utilizing high-permeability grades (e.g., 23RK075, 27P095) to ensure low hysteresis loss.
- Step-Lap Shear Technology: Our CNC-controlled longitudinal shearing lines implement multi-step lap joints, which reduce the flux density at the joints and lower noise levels by 3–5 dB.
- Burr Control: We maintain burr heights below 0.02mm, effectively preventing interlaminar short circuits that cause localized overheating.
3. Global Supply Chain & Customization
Whether you are a transformer manufacturer in Europe, Southeast Asia, or the Americas, precision is paramount. We provide:
- Distributed Gap Cores for specialized reactors.
- Laminated Cores for standard distribution transformers.
- Custom Geometric Tolerances to ensure seamless assembly.
