Low Core Loss CRGO Silicon Steel Coil for Transformer Cores
url: /crgo-silicon-steel-coil
Our CRGO (Cold Rolled Grain Oriented) silicon steel coils are engineered for transformer core applications. With low core loss and high magnetic induction ranging from 1.50T to 1.95T, these coils ensure superior energy efficiency in power transformers. Thickness options from 0.15mm to 1.00mm and widths up to 1250mm provide flexibility for various lamination designs. Available with C2, C3, C4, and C5 insulation coatings.
Key Selling Points
- Low core loss: Magnetic induction 1.50T-1.95T reduces energy dissipation during transformer operation, improving overall efficiency.
- Grain-oriented structure: Optimized magnetic flux path maximizes permeability in the rolling direction, ideal for transformer cores.
- Insulation coatings C2-C5: Enhanced interlaminar resistance minimizes eddy current losses, extending transformer lifespan.
- Wide dimension range: Thickness 0.15-1.00mm and width 20-1250mm accommodate diverse core geometries.
- ASTM/JIS/EN/GB standards: Meets international specifications, ensuring reliability in global projects.
