The role of oriented electrical steel in transformers
* The first is the core material:
Silicon steel is used as the core component of transformer equipment, and the core component of the transformer is the core. The core component of the transformer is composed of oriented electrical steel laminations. The responsibility of the core is to transfer magnetic flux between the primary and secondary windings. High-quality oriented electrical steel can ensure that the core has low loss and high magnetic permeability, thereby further improving the performance of the transformer.
* The second role is to reduce losses:
No matter what equipment will produce losses during operation, transformers are no exception. Transformers will produce iron losses (including hysteresis losses and eddy current losses) during operation. Oriented electrical steel can greatly reduce these losses, reduce energy waste, and improve the overall efficiency of the equipment due to its special grain orientation and thin specifications. And tell you that the steel loss values of silicon steel of different specifications are also very different.
* The third role is to improve equipment efficiency and stability:
Silicon steel has very good performance. The high efficiency of magnetic permeability and low loss characteristics enable oriented electrical steel to provide stable performance in transformers, reduce heat generation, and extend the service life of equipment.
How to read the grade of electrical steel (silicon steel)?
First of all, what is the core indicator of electrical steel? Of course, it is its low loss! In the process of magnetic and electrical energy conversion, energy will be lost in the form of heat, noise, etc. All indicators related to loss are key indicators of electrical steel.
Nominal Thickness | Nominal thickness tolerance | Longitudinal thickness tolerance | Traverse thickness tolerance | Width tolerance | Flatness | Camber within 2m |
mm | mm | mm | mm | mm | % | mm |
0.18 | ±0.015 | ≤0.020 | ≤0.010 | 0~+1 | ≤1.5 | ≤0.9 |
0.20 | ±0.015 |
0.23 | ±0.020 | ≤0.025 | ≤0.015 |
0.27 | ±0.025 |
0.30 | ±0.025 |

In fact, the naming of electrical steel grades usually includes the following four indicators: silicon steel thickness, silicon steel type, silicon steel iron loss, and steel coating. Cold Rolled Steel Coil silicon steel thickness: often marked with 100 times the nominal thickness (mm), such as 50 represents 0.5mm thickness
Silicon steel type: often identifies the type of electrical steel, such as non-oriented, oriented, oriented for UHV transformers, medium frequency non-oriented, etc.
Silicon steel iron loss: often marked with 100 times the iron loss guarantee value, such as the common values of 600, 800, etc.
Steel coating: represents the type of insulating coating on the surface of electrical steel, such as semi-organic thin coating, self-adhesive coating, etc.
About Steel Coil Non-oriented: P15/50, the iron loss value per Kg of core material when magnetized to a magnetic induction value of 1.5T at a frequency of 50Hz (W/Kg);
Oriented: P17/50, the iron loss value per Kg of core material when magnetized to a magnetic induction value of 1.7T at a frequency of 50Hz (W/Kg);
