Cold rolled non oriented electrical steel 35WW230, 35WW250,…

What is cold rolled non oriented electrical steel?

Cold-rolled non-oriented electrical steel (CRNO steel or CRNO electrical steel) is a type of steel that is specifically designed for use in electrical power and distribution transformers, as well as other electromagnetic applications. It is also known as silicon steel or electrical steel.

One of the key characteristics of CRNO steel is its high magnetic permeability, which means it can conduct magnetic flux with low energy loss.

CRNO steel is also known for its low core loss, which refers to the amount of energy that is converted into heat when the steel is subjected to an alternating magnetic field. Low core loss is important for efficient operation of electrical transformers, as it helps minimize energy waste and increases the overall efficiency of the transformer.

Feature

The product exhibits desirable magnetic properties, including low core loss, high permeability, and excellent performance in various applications. It also possesses good thickness tolerance, with minimal differences in thickness parallel and perpendicular to the direction of rolling, and a high lamination factor. The product is suitable for punching and cutting, with precise dimensional tolerance. The insulation coating is characterized by minimal color deviation, strong adhesiveness, and excellent resistance to heating and corrosion, with high insulation coating resistance. There are multiple options for insulation coating available for production. Furthermore, the product has been tested by professional inspection organizations and found to comply with international and domestic environmental regulations, including EU RoHS and REACH, with regards to hazardous substances.
