The stacked transformer core is designed for high-performance power and distribution transformers, offering low core loss, excellent magnetic performance, and long-term stability. Made from cold-rolled grain-oriented (CRGO) silicon steel, each lamination is precisely stacked to reduce eddy current loss, minimize noise, and optimize magnetic flux distribution.

This laminated transformer core supports both dry-type and oil-immersed transformer designs. With customizable dimensions and core configurations, it is ideal for OEMs, industrial power systems, and transformer manufacturers who require reliability and efficiency in compact transformer construction.

These cores are manufactured under strict quality controls and comply with global electrical standards to ensure consistent performance in demanding applications.

 Features:

• CRGO silicon steel lamination for minimal magnetic losses

• Low noise and vibration during operation

• High stacking factor and space-efficient design

• Custom-built to match voltage and capacity requirements

• Compatible with single-phase and three-phase systems

• Suitable for dry-type and oil-filled transformers

• Manufactured in accordance with IEC and ANSI standards
