Silicon Steel Sheet of Transformer Product Description
Silicon steel, also known as silicon steel Sheet or Electrical Steel, it is a ferro-silicon soft magnetic alloy steel with very low carbon content, usually containing 0.5% to 4.5% silicon. The addition of silicon can increase the resistivity and maximum permeability of iron to reduce the coercivity, iron loss and magnetic aging.
Silicon Steel Core Feature
- High Magnetic Permeability, Low Excitation Loss
- Low Iron Loss, Excellent Energy Efficiency
- Stable Magnetic Properties, Long Service Life
- Balanced Processability and Strength
Electrical Silicon Steel Core Application
- Power System Equipment
Large power transformers (500kV and above)
Reactors and transformers
- Motor Field
Industrial motors (fans, water pumps, machine tool motors)
New energy vehicle drive motors
Household motors (air conditioner compressors, washing machine motors)
- Electronic Equipment
Distribution transformers (household/commercial)
Switching power supply transformers (chargers, adapters)
