Silicon steel for Transformer plays an important role in optimizing transformer efficiency

The silicon steel for transformer, also known as electrical silicon, is a special steel containing silicon that can exhibit some special magnetic properties, such as creating a hysteresis region, increasing permeability, and reducing core losses, and silicon steel for transformer is a soft magnetic alloy widely used in the field of electrical engineering.

Silicon Steel for Transformer is usually manufactured in cold rolled form and is typically less than 2 mm thick. Multiple pieces of electrical steel are often pressed into stacks, commonly known as silicon steel sheets for transformer, for use in the cores of stator and rotors in transformers and electric motors. After being pressed into stacks, electrical steel is usually cut and shaped using a dimple die, laser or EDM process.

1.Silicon Steel for Transformer – Classification Orientation

Silicon steel for transformer can be divided into two main categories: oriented and non-oriented.

The magnetic properties of oriented silicon steels are strongly directional, with the lowest iron loss values in the rolling direction, the highest permeability and high magnetic susceptibility under certain magnetizing fields. Oriented silicon steel for transformer content of about 3%, and requires a low content of oxide inclusions in the steel, at the same time must contain a certain inhibitor (MnS, A1N), because more for the manufacture of transformer cores, so silicon steel for transformer also known as cold-rolled transformer steel.

Non-oriented silicon steel has a very low carbon content, silicon content between 0.8% -4.8%, the addition of silicon can improve the iron resistivity and maximum permeability, reduce the coercive force, core loss (iron loss) and magnetic aging. In the deformation and annealing of the steel plate in the grain was irregular orientation distribution, hot and cold rolled from the thickness of 1 mm or less silicon steel sheet.This silicon steel for transformer is very good performance.

2.Silicon Steel for Transformer- Usage

According to the use of silicon steel for transformer is divided into three categories: hot rolled silicon steel, cold rolled electrical steel and special purpose silicon steel. Cold rolled sheet thickness uniformity, good surface quality, high magnetic, and gradually replace the hot rolled sheet. Low-silicon sheet contains less than 2.8% silicon, it has a certain mechanical strength; high-silicon sheet contains 2.8%-4.8% silicon, it has good magnetic properties, but more brittle.

The silicon steel for transformer has good processability: Silicon steel sheets are easy to cut and stack, suitable for transformer core manufacturing

The silicon steel for transformer used in the manufacture of transformer cores, can effectively improve the performance of the transformer, so that the transformer has a higher efficiency, lower noise, as well as smaller size and weight.

Our silicon steel products for transformers are a model of excellence in the industry! They have extremely low iron loss, which significantly reduces the energy consumption of the transformer, making a great contribution to energy saving and emission reduction, and at the same time saving a lot of operating costs for customers.

High magnetic induction strength makes the transformer output stronger power under the same volume, excellent performance and extraordinary efficiency. Its excellent stacking performance ensures that the iron core fits tightly, which improves the overall stability of the transformer, effectively reduces noise and vibration, and makes the equipment run more smoothly and quietly.

In addition, the product surface is flat and smooth, and the insulating film is firmly attached, which further enhances the insulation performance and service life. Our silicon steel products can be perfectly adapted, with its excellent performance and reliable quality, to provide a solid guarantee for the transmission and conversion of electric power, to help electrical equipment toward a new era of high efficiency, energy saving, environmental protection!
