Product Description
EI Type Transformer Core
The EI type transformer core is a widely used magnetic core structure composed of E-shaped and I-shaped laminated silicon steel sheets. Designed for efficient magnetic flux conduction, it is commonly employed in power transformers, inductors, and various electrical equipment. Its stacked-layer construction reduces eddy current losses, making it ideal for low- to medium-frequency applications such as power supplies, lighting systems, and industrial control devices.
Product Specifications
Parameter Specifications
Core Material High-grade grain-oriented or non-oriented silicon steel
Lamination Thickness Standard options include 0.35 mm, 0.5 mm, and 0.65 mm
Coating Insulated surface coating to minimize interlaminar losses
Standard Sizes Customizable based on power ratings (e.g., EI-48, EI-57, EI-66, etc.)
Operating Frequency 50/60 Hz to 1 kHz
Core Loss Optimized for minimal hysteresis and eddy current losses (specific values depend on grade and thickness)
Key Advantages
High Magnetic Efficiency
Silicon steel's high permeability ensures excellent magnetic flux conduction, improving overall transformer performance.
Reduced Energy Loss
Laminated design and insulated coating significantly cut down eddy current and hysteresis losses, enhancing energy efficiency.
Mechanical Stability
The interlocking E and I layers provide robust structural integrity, reducing vibrations and noise during operation.
Cost-Effective Manufacturing
Simple geometry allows for easy punching, stacking, and assembly, lowering production costs.
Wide Applicability
Suitable for diverse voltage and power requirements across industries, from consumer electronics to heavy machinery.
