Magnetic steel core" is a general term that can refer to the core of a transformer, as well as the cores used in other electromagnetic devices such as inductors, motors, and generators.

In the context of transformers, magnetic steel core typically refers to the laminated core made of silicon steel (CRGO or amorphous steel), which is specifically designed to enhance magnetic performance and minimize energy losses. It serves as the central component of a transformer, providing a path for magnetic flux and facilitating energy transfer between the primary and secondary windings.

Why is it called "magnetic steel core"?

The core is made of magnetic materials (usually ferromagnetic) that have high magnetic permeability, allowing efficient flux flow.

Steel (often with added silicon),silicon steel is commonly used because it offers a good balance of magnetic properties, mechanical strength, and cost-effectiveness.

Is it a general term for transformer cores?

Yes, "magnetic steel core" is a broad term and can refer to any type of core made from magnetic steel. However, depending on the design and application, there are specific types of transformer cores, such as:

CRGO (Cold-Rolled Grain-Oriented) Steel Cores

Most common for power and distribution transformers.

Amorphous Steel Cores

Used for high-efficiency transformers due to lower core losses.

Laminated Steel Cores

Thin sheets of magnetic steel stacked to reduce eddy current losses.

Wound Cores

Continuous strips of magnetic steel wound into a closed-loop core.

However, in professional contexts, it's often more precise to specify the type of transformer core, such as step-lap cores, distributed gap cores, or wound cores, to clarify the design and application.

Our CRGO cores, designed for transformers up to 10 MVA, come pre-tested for no-load losses and are delivered fully assembled and ready for coil insertion.
