CRGO Mother Coil Supplier in India
Cold Rolled Grain Oriented Electrical Steel
By Rasquinha Transcore Electricals Pvt Ltd
Rasquinha Transcore Electricals Pvt Ltd is a trusted supplier and processor of CRGO Mother Coils (Cold Rolled Grain Oriented Electrical Steel) for transformer manufacturers across India and export markets. Our CRGO steel is widely used in power, distribution, and instrument transformers due to its superior magnetic performance and low core loss characteristics.
What is CRGO Mother Coil?
CRGO electrical steel is manufactured with approximately 3% silicon content and extremely low carbon and phosphorus levels. This precise composition enhances magnetic permeability while minimizing hysteresis and eddy current losses, making it ideal for high-efficiency transformer core applications.
Grain Oriented Electrical Steel โ High Magnetic Efficiency
CRGO steel undergoes advanced cold rolling and annealing processes that align the crystal grains in a specific rolling direction. This grain orientation delivers:
Low core loss
Reduced magnetizing current
Higher transformer efficiency
Long operational life
Thickness & Width Range
We supply CRGO mother coils in multiple thicknesses to suit transformer design requirements:
0.23 mm
0.27 mm
0.30 mm
Up to 0.35 mm
Standard width range:
600 mm to 1300 mm
(Custom widths available on request)
Coil Weight
Typical CRGO mother coil weight ranges from 2 MT to 5 MT per coil, depending on thickness and width.
Surface Finish & Insulation Coating
Our CRGO electrical steel is processed with:
Precision cold rolling
Controlled annealing
High-quality insulation coating
This ensures excellent surface finish, electrical insulation, and consistent magnetic performance.
Applications
Power transformers
Distribution transformers
Instrument transformers
Reactors and high-efficiency magnetic cores
CRGO steel plays a critical role in reducing no-load losses and improving overall transformer efficiency.
