Silicon Electrical Steel Product Description
Electrical steel (silicon steel sheet) is mainly divided into two categories: grain-oriented electrical steel and grain non-oriented electrical steel. The direction of easy magnetization grains of oriented electrical steel is distributed along the rolling direction. The rolling direction has excellent characteristics such as high magnetic induction, low iron loss and low magnetostriction.
At the same time, it can also be processed by magnetic domain refinement technology to obtain lower iron Loss of performance, widely used in the field of transformer industry. The grain direction of non-oriented electrical steel is randomly distributed, and the electromagnetic properties are uniform in all directions. It is widely used in the motor industry.

Non-Oriented Silicon Steel Application
Power Transformer Cores: It is most widely used in large main transformers for high-voltage power transmission in power grids, as well as small transformers for power distribution in residential areas and factories. With its low iron loss characteristic, it can reduce electrical energy waste during the long-term operation of transformers and ensure efficient power transmission in the power grid.
Special Reactor Cores: It is used in reactors for harmonic suppression and voltage stabilization in power grids, as well as filter reactors in the new energy field. Its high magnetic permeability can ensure the stable magnetic circuit of reactors under high load and avoid performance fluctuations.
Precision Instrument Transformers: For current transformers and voltage transformers used to measure current and voltage in power systems, they rely on its high magnetic performance to ensure accurate signal transmission and avoid measurement errors or false triggering of protection devices.
