Silicon steel sheet: key material in the electrical field

图片
In the modern electrical industry, silicon steel sheet is an extremely important soft magnetic material, widely used in various types of electromagnetic equipment such as motors, transformers, reactors, etc., and plays a key role in the efficient operation of the power system. Silicon steel sheet, also known as electrical steel sheet, is a silicon-iron alloy with a silicon content of 0.5%-4.5%. The addition of silicon significantly increases the resistivity of steel and reduces the eddy current loss generated by the iron core in the alternating magnetic field, which is an important characteristic of silicon steel sheet that distinguishes it from ordinary steel. At the same time, silicon steel sheet also has a higher magnetic permeability, which can conduct magnetism more effectively, so that electromagnetic equipment can generate sufficient magnetic flux under a smaller excitation current, greatly improving energy utilization efficiency. From the manufacturing process p...

Understanding EI Lamination for Transformers

图片
Transformer technology plays a critical role in electrical systems, with EI laminations being one of its core components. These laminations are designed to minimize energy losses and enhance efficiency. EI lamination refers to the thin layers of silicon steel arranged in the shape of the letters “E” and “I” to form the magnetic core of a transformer. These laminations are used to reduce energy losses caused by eddy currents and improve the magnetic properties of the core. Importance of EI Laminations in Transformers 1. Minimizing Eddy Currents: – Laminations decrease the loop area for eddy currents, reducing energy losses. – Insulated coatings between layers prevent the flow of these currents. 2. Enhancing Magnetic Efficiency: – Silicon steel is chosen for its excellent permeability and low hysteresis loss. – The lamination design optimizes the flow of magnetic flux. 3. Reducing Heat Generation: – Lower energy losses translate to reduced heat, increasing transformer li...
