Laminated Transformer Core

Construction Characteristics:

1. Lamination: The core is made from thin silicon steel sheets (typically less than 0.5 mm thick) that are stacked or laminated together. Each sheet is coated with a non-conductive insulation material to reduce eddy current losses.

2. Orientation: The layers can be arranged in various orientations. Laminations are often oriented in the direction of the magnetic field to improve the core’s magnetic properties (known as grain-oriented laminations).

1. Reduction of Eddy Current Losses

By laminating the core, the path for eddy currents is broken up, which decreases their magnitude and, subsequently, energy losses.

2. Lower Hysteresis Losses

Furthermore, laminating the core also helps minimize hysteresis losses. The thin insulation layers between the laminations reduce the magnetic coupling between them, reducing the hysteresis effect and associated losses.

3. Enhanced Magnetic Properties

Laminated transformer cores can be designed to enhance specific magnetic properties, such as permeability and saturation levels, making them suitable for various transformer designs.

4. Improved Efficiency

Using transformer laminated cores can improve the overall efficiency of transformers, particularly in power and distribution applications. This makes them suitable for applications where energy conservation is important.

5. Better Thermal Performance

The laminated structure can help dissipate heat more effectively, improving the thermal performance of the transformer.

6. Better Performance at Higher Frequencies

Laminated transformer cores can handle the magnetic flux changes better, making them suitable for higher frequency applications compared to solid transformer core designs.

7. Cost-effectiveness

The use of silicon steel laminations is not only effective in reducing losses but also often more cost-effective than some alternative materials or core designs.

Laminated transformer cores are widely used in many applications, including:

1. Transformer Manufacturing: primarily used in the fabrication of various transformers, including power transformers, distribution transformers, current transformers, etc.

2. Factory Equipment: applied in industrial machinery and equipment that require transformers to step down or step up voltages.

3. Audio Equipment: employed in audio transformers for amplifiers and other audio devices due to their ability to handle various frequencies efficiently.

4. Renewable Energy: used in transformers for wind turbines, solar inverters, and other renewable energy systems where efficiency is critical.

5. Small Equipment: found in smaller transformers used in electronics, such as charger units and power supplies.

6. Inductive Components: used in inductors and chokes in electronic circuits for filtering and energy storage.

1. High-quality Silicon Steel Materials

We maintain long-term and stable direct supply relationships of silicon steel wafers with many well-known domestic and foreign steel mills, such as Baosteel, WISCO, and Shoudu Steel. Thus we can fully ensure the best quality of silicon steel chips — the main material of the transformer core.

2. Advanced Automatic Production

Silicon steel adopts the international advanced automatic intelligent production line processing, with high processing precision, small burr, good flatness, and high efficiency, thus greatly shortening the delivery cycle.

3. Intelligent Manufacturing

No driving in the whole manufacturing process, and the intelligent workshop has constant temperature and humidity and remains dust-free. The whole process from raw materials to the finished iron core reduces the extra stress of silicon steel, reduces the manufacturing process coefficient of the iron core, and effectively ensures the product performance and quality.

4. Unique Processing Method

We adopt unique full-sequence lamination methods, advanced processes, and equipment, which have a remarkable effect on energy saving and environmental protection of products.

Besides, the clam parts are made of high strength steel, formed by numerical control bending. Compared with groove steel, they have mechanical strength, more accurate size and positioning, and smooth and beautiful appearance’s surname.

5. Complete Quality Assurance System

Quality is a core value at GNEE EC. We conduct factory acceptance testing (FAT), type testing, and third-party inspection tests to ensure excellence. We also conform to ISO 9001:2015, AS 9100, and AS 9003 quality management standards for all our transformer core products. And we have advanced CMM equipment to inspect final products.
