KNOWLEDGE BASE --- The Importance of Silicon Steel Sheet for Transformers
Silicon steel sheets are regarded as the primary material to form transformer core as for transformers. Silicon steel is a kind of steel that contains silicon and its silicon content ranges from 0.8% to 4.8%. Why should transformer cores be made of silicon steel? This is because silicon steel is a magnetic material with strong magnetic conductivity. It can generate a large amount of magnetic induction in current coils. Then the volume of transformer can be reduced.

The power loss of transformer in the communication state happens not only in the resistance of coil, but also in the iron core under the magnetization of alternating current. Generally speaking, the power loss in iron core is called iron loss. The iron loss is caused by two factors: one is hysteresis loss and the other is eddy current loss. Hysteresis loss is the iron loss that occurs in the process of magnetization of iron core due to the presence of hysteresis. The magnitude of this loss is proportional to the size of the area enclosed by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow and when silicon steel is used to make transformer, the hysteresis loss of iron core is small, which can greatly reduce the heating.

When the transformer is in operation, the magnetic flux generated by the alternating current in the coil is alternating certainly. The changing magnetic flux induces current in the iron core. The induced current generated in the iron core circulates in a plane perpendicular to the flow direction, so it is called eddy current loss, which also causes the iron core to heat up. In order to reduce the eddy current loss, the iron core of transformer is laminated with  insulated silicon steel sheets. The eddy current passes through a smaller section in a long and narrow circuit to increase the electric limit of the eddy current circuit. At the same time, the silicon in the silicon steel increases the resistivity of material and also has the effect of reducing the eddy current.

All in all, silicon steel sheet plays an important role in transformer and determines the lifespan of transformer.
