CRGO Core Material Supplier in India (Transformer Core Lamination Sheets)

WHAT IS CRGO CORE
CRGO core refers to transformer core material made from Cold Rolled Grain Oriented (CRGO) electrical steel, specifically designed to achieve high magnetic permeability and extremely low core losses. Due to its grain-oriented structure, CRGO core material allows magnetic flux to flow efficiently in the rolling direction, significantly reducing hysteresis and eddy current losses. This makes CRGO lamination core sheets the preferred material for manufacturing energy-efficient transformer cores used in both distribution and power applications across India.
CRGO core sheets are typically available in thickness ranges of 0.23 mm, 0.27 mm, and 0.30 mm, with different grades offering varying levels of core loss performance. Transformer manufacturers and core cutting units rely on high-quality CRGO lamination sheets to ensure optimal efficiency, reduced energy losses, and long operational life of electrical transformers.
As a trusted CRGO core material supplier in India, S M Steels provides both prime and secondary CRGO core sheets suitable for diverse transformer applications.
TYPES OF CRGO CORE MATERIALS
CRGO core materials are supplied in multiple forms depending on the requirements of transformer manufacturers and core cutting units.
CRGO Lamination Sheets
CRGO lamination sheets are the most commonly used format for transformer core assembly. These sheets are precision cut and processed into shapes such as mitered and V-notched laminations for efficient core building.
CRGO Slit Coils
Slit coils are narrow-width CRGO coils used by core cutting units to produce lamination sheets. These are widely used where custom sizes and high-volume cutting operations are required.
Assembled Transformer Cores
Fully assembled transformer cores are manufactured using CRGO lamination sheets. While S M Steels primarily supplies CRGO core materials and sheets, these materials are used by manufacturers to produce assembled transformer cores.

TRANSFORMER APPLICATIONS
CRGO core material plays a critical role in transformer performance and efficiency.
Distribution Transformers
Used in power distribution networks, CRGO core sheets help reduce no-load losses and improve energy efficiency.
Power Transformers
High-grade CRGO lamination core sheets are used in large power transformers where efficiency and performance are critical.
Core Cutting Units
Core cutting units depend on CRGO slit coils and lamination sheets to manufacture precision transformer core components.
Transformer manufacturers across India rely on consistent supply of transformer lamination core sheets to maintain production and meet industry demand.
PRIME VS SECONDARY CRGO CORE MATERIAL
Prime CRGO core material offers the highest quality with the lowest core losses, making it ideal for high-efficiency transformer applications where performance and reliability are critical. It typically has a uniform surface finish and consistent magnetic properties, which ensures better operational efficiency. In contrast, secondary CRGO core material is more cost-effective and suitable for budget-oriented or general transformer applications. While it may have slightly higher core losses and some surface variations, it remains a widely used option for many manufacturers depending on their specific requirements. S M Steels supplies both prime and secondary CRGO core sheets, helping buyers choose the right material based on application, performance expectations, and pricing.
AVAILABLE FORMATS
CRGO core materials are available in various formats to suit manufacturing processes.
-
Regular CRGO lamination sheets
-
Jumbo CRGO core materials
-
Mitered laminations
-
V-notch and Double V-notch laminations
-
