FAQ

1. What material is used for silicon steel toroidal cores?

Our silicon steel toroidal cores are made from grain-oriented silicon steel (CRGO). This material offers favorable magnetic properties and is commonly used in instrument transformer applications.

2. What thicknesses are available for silicon steel cores?

Available thicknesses include 0.05mm, 0.08mm, 0.10mm, 0.20mm, 0.23mm, 0.27mm, 0.30mm, and 0.35mm. Custom material requirements can also be discussed.

3. What are silicon steel toroidal cores used for?

They are commonly used in current transformers, voltage transformers, electrical metering equipment, and power distribution systems.

4. Why is CRGO silicon steel used for toroidal transformer cores?

CRGO (Cold-Rolled Grain-Oriented) silicon steel offers favorable magnetic properties along its rolling direction and is widely used in transformer core manufacturing. Its magnetic characteristics make it suitable for applications requiring efficient magnetic flux conduction and low core losses.

5. What is the difference between a silicon steel toroidal core and a laminated transformer core?

A silicon steel toroidal core typically features a ring-shaped magnetic structure, while laminated transformer cores are assembled from stacked steel sheets in configurations such as E-I or U-I shapes. Their selection depends on transformer design, winding requirements, installation space, and electrical performance targets.
