Features:
Magnetic permeability: The iron core is a magnetic conductive part in the transformer, and it is in a constantly changing electromagnetic field, and its magnetization and magnetic induction intensity are constantly changing. The magnetic permeability of the core makes the primary coil better coupled with mutual inductance, so as to realize magnetoelectric conversion.
Skeleton role: The iron core is also used as the skeleton of the transformer, which is used to fix the various components of the transformer, such as coils, insulation parts, leads, etc.

Focus on hot spots

Transformer core grounding and safety

The manufacturing process of transformer iron core involves many links, including cutting, stacking and fixing of silicon steel sheet.

Application and classification of transformer core

Transformers according to its use can be divided into power transformers, test transformers, instrument transformers and special purpose transformers and other types.

Material and structure of transformer core

Material: Transformer core is usually made of silicon steel sheet or NiFe (nickel-iron) alloy and other materials.
