Oil-immersed Transformer Core

Oil-immersed transformer cores offer several advantages:

1. Good Magnetic Performance:

Made from silicon steel laminations, the core possesses high magnetic permeability and low losses, enhancing the overall efficiency of the transformers.

2. Enhanced Cooling:

The core and windings are immersed in the insulating oil. This oil helps to effectively dissipate heat, allowing the transformer to operate at higher capacities without overheating.

3. Improved Insulation:

The oil also provides excellent dielectric strength, enhancing the overall insulation of the transformer core.

4. Reduced Noise Level:

Oil immersed transformer cores operate more quietly than dry-type transformer cores due to the damping effect of the oil, which absorbs vibrations and noise generated during operation.

5. Protection Against Corrosion:

The insulating oil can help protect the core components from moisture and corrosion, thereby enhancing their durability.

6. Fire Resistance:

The insulating oil used in these transformer cores has high flash points, which adds a level of fire resistance compared to air-cooled types.

7. Increased Reliability:

The cooling and insulation provided by the oil contribute to the longevity of the core.

8. Improved Efficiency:

The reduced energy losses due to the properties of silicon steel and the cooling effect of the oil lead to higher operating efficiency, making oil immersed transformer cores more efficient in transformer applications.

Oil-immersed transformer cores are widely used in various applications, including:

1. Transformer Manufacturing: this type of core is widely used in the manufacturing of oil immersed transformers.

2. Power Generation and Distribution: They are commonly used in substations and power plants to step up or down voltage levels for efficient power transmission.

3. Industrial Applications: Oil-immersed transformer cores are used in manufacturing facilities to supply power to heavy machinery and equipment that require high voltage levels.

4. Renewable Energy Systems: They are utilized in wind farms and solar power plants to manage voltage levels and connect to the grid.

5. Railway Systems: They are used in railway electrification systems to provide power to trains.

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.
