Specifications for 27mm Thickness Silicon Steel with Iron Loss Values
Below is a clear representation of the specifications for silicon steel with a thickness of 27mm and corresponding iron loss values of 105 and 120:
| Thickness (mm) | Iron Loss Value (W/kg) | Grade | Core Loss (P15/50) | Applications | Additional Notes |
|---|---|---|---|---|---|
| 27.0 | 105 | Grain-Oriented Steel | ≤ 1.05 | Transformers, Motors | Optimized for energy efficiency |
| 27.0 | 120 | Grain-Oriented Steel | ≤ 1.20 | Transformers, Generators | Higher magnetic flux density |
Key Points:
Grade Matching: These values correspond to premium grain-oriented silicon steel designed for reducing energy losses in transformers and motors.
Core Loss (P15/50): Indicates the iron loss under a magnetizing frequency of 50 Hz and induction of 1.5T.
Key Features of Silicon Steel Laminations
- Grain-Oriented Silicon Steel (CRGO)
Optimized for low core loss and high magnetic permeability.
Enhances transformer efficiency while minimizing energy dissipation.
- High Magnetic Induction
Essential for improving the performance of power transformers and large motors.
- Dimensional Precision
Customizable sizes and thicknesses to meet exact project requirements.
Common sizes include 0.23mm and 0.35mm thickness for transformer steel laminations.
- Eco-Friendly Performance
Reduces energy loss, making it ideal for sustainable and green power applications.
Key Applications in Transformers
- Power Transformers
Core Material: 27mm silicon steel is widely used in the core of power transformers, where it efficiently handles high voltage and current.
Benefits: The material's low iron loss (e.g., 105 or 120 W/kg) minimizes energy wastage during power transmission, making it essential for grid infrastructure.
- Distribution Transformers
Purpose: These transformers are used in electrical distribution networks, where consistent energy supply is critical.
Advantages: Silicon steel's excellent magnetic properties ensure reduced noise, lower heat generation, and enhanced durability.
- Specialized Transformers
Application: Used in high-frequency transformers for industrial and renewable energy sectors.
Performance: Grain-oriented silicon steel ensures precision in magnetic flux direction, improving transformer efficiency and reducing operational costs.
Why 27mm Silicon Steel Is the Industry Standard
| Property | Performance Advantage | Benefits for Transformers |
|---|---|---|
| Thickness | 27mm provides structural stability for large transformers | Ensures consistent operation under heavy loads |
| Low Core Loss | 105/120 W/kg at 1.5T magnetic flux density | Reduces energy wastage and heat generation |
| Grain Orientation | Strongly aligned grains optimize magnetic performance | Improves flux flow and transformer efficiency |
| Magnetic Permeability | Excellent magnetic response to alternating current | Minimizes eddy current losses |
