What specific types of high-grade magnetic materials are commonly used in the construction of the transformer core?

The Energy-Saving Three-Phase Oil-Immersed Distribution Transformer core is a crucial component responsible for the efficient transfer of magnetic energy between the primary and secondary windings. Various high-grade magnetic materials are used in the construction of transformer cores. Two common types are:

Grain-Oriented Silicon Steel:

Grain-oriented silicon steel, also known as electrical steel or transformer steel, is a widely used material for transformer cores. It is specifically processed to have grains aligned in a single direction, enhancing its magnetic properties. This alignment helps reduce hysteresis and eddy current losses in the core, making it highly efficient for power transformers.

Amorphous Metal Alloys:

Amorphous metals, or metallic glasses, are another type of material increasingly used in transformer cores, especially for energy-saving applications. These alloys have a disordered atomic structure, lacking the regular crystalline arrangement found in traditional materials. Amorphous metals exhibit lower core losses, particularly hysteresis and eddy current losses, compared to grain-oriented silicon steel. This characteristic makes them highly desirable for enhancing the energy efficiency of Energy-Saving Three-Phase Oil-Immersed Distribution Transformers.

The choice between these materials depends on factors such as the desired efficiency, cost considerations, and specific transformer design requirements. While grain-oriented silicon steel is a long-established and cost-effective choice, amorphous metals offer superior energy efficiency but may come at a higher initial cost. Transformer manufacturers carefully select the core material based on the intended application and performance goals.
