Silicon Steel Transformer Core

Technical Specifications of Silicon Steel Transformer Cores in GNEE EC

What Is Silicon Steel Transformer Core?

Silicon steel transformer core is a type of magnetic iron core made from silicon steel (also known as electrical steel), an alloy of iron with silicon. The addition of silicon can greatly enhance the steel’s electrical resistivity and reduce hysteresis losses, making it an ideal material for transformer cores. Nowadays, silicon steel has become a commonly used material to manufacture transformer cores, offering an incredibly efficient and cost-effective solution for electricity transmission worldwide.

What Type of Silicon Steel Transformer Cores Can Gnee Provide?

At Gnee factory, we can manufacture electrical steel transformer cores in a wide range of forms, offering diverse and efficient solutions for different customers. You can get:

According to Material:

This type of transformer core can be made in either CRGO or CRNGO materials. It can be divided into:

CRGO (Cold Rolled Grain Oriented Silicon Steel) Transformer Core: Made from grain oriented silicon steel to have a highly oriented crystalline structure, which allows for improved magnetic properties in a specific direction.

CRNGO (Cold Rolled Non Grain Oriented Silicon Steel) Transformer Core: Made from non grain oriented silicon steel to have similar magnetic properties in all directions.

According to Shape:

Silicon steel transformer cores can be produced in many different shapes, like rectangular, toroidal, etc., each featuring distinct application ranges.

Silicon Steel Toroidal Transformer Core: Formed in a toroidal (doughnut) shape, widely used in toroidal transformers and other transformers.

Silicon Steel EI Transformer Core: Formed in EI shape, widely used in EI transformers and other transformers.

Silicon Steel UI Transformer Core: Formed in ui shape, widely used in ui transformers and other transformers.

Silicon Steel C-shaped Transformer Core: Formed in C shape, widely used in C transformers and other transformers.

Silicon Steel Rectangular Transformer Core: Formed in a rectangular or square shape, widely used in various transformers.

According to the Manufacturing Process

Laminated Silicon Steel Transformer Core: This type of core is made by lamination stacking technology, which can minimize air gaps, reduce losses, and enhance overall transformer performance.

Wound Silicon Steel Transformer Core: This type of core is made by advanced winding technology, which can eliminate joint losses, reduce vibration, and provide exceptional magnetic flux uniformity.

What Are the Advantages of Silicon Steel Transformer Cores Offered by GNEE EC?

1. High Magnetic Permeability: Silicon steel offers significantly higher magnetic permeability compared to traditional iron cores. This means that it requires less energy to magnetize the core and is able to ensure optimal flux density, translating into improved efficiency and performance.

2. Ultra-low Core Losses: Using high-grade grain-oriented (GOES) & non-oriented (NOES) silicon steel and thin lamination technology can significantly lower hysteresis and eddy current losses. This enhances energy efficiency for long-term savings, making it ideal for power transformers and other high-efficiency applications.

3. Reduced Size and Weight: Transformer cores constructed from silicon steel tend to be lighter and more compact for the same power rating compared to conventional materials, making them easier to install, transport, and use in various applications without compromising performance.

4. Great Durability and Longevity: Our silicon steel transformer cores are resistant to aging, corrosion, and mechanical stress, able to withstand varying environmental conditions. This durability leads to longer life cycles for transformers, reducing replacement costs over time.

5. Improved Thermal Performance: Silicon steel transformer cores can maintain their magnetic properties over a wide temperature range, ensuring reliable operation under varying conditions.

6. Cost-Effective Solutions: Compared to other advanced materials like amorphous metal, the silicon steel transformer core remains cost-effective, making it a preferred choice for transformer manufacturers.

What Are the Main Applications of Gnee’s Silicon Steel Transformer Cores?

Our silicon steel transformer cores are suitable for a variety of applications, including:

1. Transformer Manufacturing: Extensively used in the manufacturing of various transformers, including silicon steel transformers, distribution transformers, audio transformers, instrument transformers, etc.

2. Power Generation: Essential in power plants for stepping up or stepping down voltage levels, ensuring efficient energy distribution.

3. Industrial Machinery: Commonly found in various industrial applications where efficient power management is necessary.

4. Renewable Energy Systems: Used in wind and solar inverters to maximize energy conversion efficiency.

5. Automotive and Electric Vehicles: Increasingly important in electric vehicle chargers and drive systems for enhanced performance.

6. Inductive Components: used in inductors, chokes, and reactors in power electronics and other applications requiring magnetic energy storage.
