Electrical steel

Electrical steel

Electrical steels are distinguished by their excellent electro-magnetic properties. There are two categories: grain-oriented electrical steel and non-oriented electrical steel.

PG-Core(Grain-Oriented Electrical Steel)

The grain's easy magnetization direction is aligned to the rolling direction. Therefore, this product features excellent magnetic properties in the rolling direction. It is widely used for large-sized power transformers or large or small size transformers

PN-Core(Non-Oriented Electrical Steel)

The non-oriented electrical steel features even magnetic properties in the rolling direction and in other directions. They are widely used for iron core materials of rotating machines ranging from large-size power generators to small-size precision electric motors. They are also desirable for iron core of small-size power transformers.
