Transformers use silicon steel sheets as their core material for the following main reasons:

High Permeability: Silicon steel sheets have a high permeability, meaning they can effectively conduct magnetic flux, reducing the transformer's hysteresis loss.

Low Hysteresis Loss: Silicon steel sheets exhibit very low hysteresis loss, which means they can retain minimal energy loss when subjected to varying magnetic field strengths, making transformers more efficient.

Low Eddy Current Loss: Silicon steel sheets also have low eddy current losses because they are typically thin and laminated, reducing the circular path of eddy currents and lowering eddy current losses.

Low Conductor Loss: Since silicon steel sheets are insulated, they perform well in terms of conducting, minimizing energy loss due to current flow through conductors.

Good Thermal Stability: Silicon steel sheets maintain stability at high temperatures, which is crucial for transformers operating over extended periods as they need to withstand high temperatures.

Reduced Magnetic Leakage Loss: The magnetic properties of silicon steel sheets help minimize the magnetic leakage loss of transformers, enhancing energy transfer efficiency.

Excellent Corrosion Resistance: Silicon steel sheets are typically coated with an oxide layer, improving their corrosion resistance and extending the lifespan of transformers.

In summary, as a core material, silicon steel sheets significantly reduce a transformer's hysteresis loss, eddy current loss, and conductor loss, enhancing efficiency, reducing energy loss, and making transformers more reliable and economical in electrical energy transmission and conversion. Therefore, silicon steel sheets are the ideal choice for transformer cores.
