Fast Delivery Smooth Surface Electrical Silicon Steel Sheet Price

Product Description

High magnetic induction oriented silicon steel sheet is the main material that constitutes the transformer core. The basic requirements for the transformer core material are low ferromagnetic loss at a certain frequency and magnetic flux density and high magnetic flux density at a certain magnetic field intensity. The size of the no-load loss of the transformer is mainly determined by the material of the silicon steel sheet. In addition, it is related to the design and manufacturing process of the iron core.

Frequently Asked Questions

What is oriented silicon steel sheet?

Oriented silicon steel sheet, also known as cold-rolled grain-oriented (CRGO) steel, is an alloy of iron and silicon designed to offer low core loss and high magnetic permeability in a specific rolling direction, making it highly efficient for electrical transformer applications.

Why is oriented silicon steel used for transformer cores?

It provides low ferromagnetic loss (core loss) at typical operating frequencies and high magnetic flux density. This helps reduce the no-load loss of transformers, boosting operational efficiency and lowering thermal generation.

What are EI laminations?

EI laminations are punched pieces of silicon steel sheets shaped like the letters "E" and "I". Stacking these pieces creates a closed magnetic path (core), which is used in inductors, small motor devices, and power transformers.

How do I choose the correct EI model specification?

You should select the model according to the dimensional specifications required for your device, specifically focusing on the outer dimensions (A and B), the center tongue width (C), stack height, and the mounting hole (aperture) diameter.

Can you customize sizes and hole placements?

Yes. Various standard models from EI-28 to EI-144 offer different aperture placements and sizes (e.g., 3.2mm, 3.5mm, 4.0mm, or without holes) to ensure optimal installation stability and fit for your hardware requirements.
