Transformer Core

2019-04-06

Transformer core, or iron core is the main magnetic circuit part of the transformer. It is usually made up of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and a surface coated with an insulating varnish. Transformer core and the coil wound thereon form a complete electromagnetic induction system. The amount of power transmitted by the power transformer depends on the material and cross-sectional area of the core.
