    Application

    Power Transformers: Silicon steel is also the material of choice for distribution and power transformer cores due to the availability of very low core loss grades with extremely high magnetic induction in the rolling direction combined with excellent permeability. This greatly enhances the energy savings and system stability.

    Energy-Saving Industrial Transformers: Suitable for medium to large-sized industrial transformers, silicon steel minimizes energy loss and still provides outstanding magnetic properties, enabling use in high efficiency power conversion systems.

    Reactors and Chokes: Ideal for inductors, reactors and choke cores in continuous load applications. It allows the least iron loss, tremendous magnetic stability and truly spectacular performances in high power electrical equipment.

    Renewable Energy Transformers: Commonly used in wind power machinery, solar inverter and other ratable of renewable energy, complies with steady operation, decreased power consumption and enhanced system efficiency.

    Electrical Distribution Equipment: Silicon steel plays the role of excellent stackability, dimensional stability and magnetic stability for a reliable power distribution system when utilized in switchgear, voltage regulators and industrial control transformers.
