CRGO Domamin Refined High Induction Product Description
Electrical steel, usually referring to cold rolled electrical steel, can be divided intotwo major categories including grain oriented electrical steel and non-orientedelectrical steel. Grain oriented electrical steel, with its easy magnetizationdirection parallel to the rolling direction, has excellent magnetic properties in thisdirection including low core loss, high permeability and low magnetostriction andis widely used in the transformer industry.
Further it can obtain lower core lossby domain refinement treatment. Meanwhile non-oriented electrical steel.featured by random distribution of grain orientation and magnetic isotropy, iswidely applicable to the motor industry.
CRGO Domamin Refined High Induction Characteristics and Advantages
- Low Loss: The domain refinement process greatly reduces hysteresis loss, minimizing electrical energy waste during equipment operation and meeting high-efficiency energy-saving requirements.
- High Magnetic Induction: The high magnetic induction intensity enables equipment to be smaller and lighter, reducing the consumption of raw materials and the demand for installation space.
- Low Noise: The optimized magnetic domain structure suppresses vibrations caused by magnetostriction, thereby reducing equipment operation noise. It is suitable for noise-sensitive scenarios (such as distribution transformers in residential areas).
CRGO Domamin Refined High Induction Application
High-voltage and extra-high-voltage power transformers, especially power grid equipment that requires high energy efficiency and low noise.
Special transformers (such as traction transformers and high-power industrial transformers) in scenarios that need to balance power density and operational stability.
