CRGO Lamination
By Rasquinha Transcore Electricals Pvt Ltd
Cold Rolled Grain Oriented (CRGO) lamination stands at the heart of modern transformer manufacturing, ensuring efficiency, reliability, and long-term performance of electrical power systems. At Rasquinha Transcore Electricals Pvt Ltd, CRGO lamination is not merely a material we process—it is a core engineering discipline shaped by precision, experience, and a deep understanding of magnetic behaviour.
CRGO steel is uniquely engineered with grains aligned in the rolling direction, dramatically reducing core loss and improving magnetic permeability. This grain orientation gives CRGO its defining characteristic: exceptional performance under alternating magnetic fields. For transformer manufacturers, this translates into lower no-load losses, reduced heat generation, and significant enhancement in electrical efficiency. As the demand for energy-efficient systems grows worldwide, the role of high-grade CRGO lamination becomes more critical than ever.
Our lamination process begins with the careful selection of high-quality CRGO coils sourced from trusted global mills. Each coil undergoes rigorous inspection to ensure consistent thickness, uniform grain structure, and optimal insulation coating. At Rasquinha Transcore Electricals Pvt Ltd, precision cutting is executed using advanced slitting, shearing, and step-lap punching technologies. This ensures minimum burr height, tight dimensional tolerance, and superior stacking quality—all essential for reducing magnetostriction and audible noise in the final transformer core.
One of the key strengths of our manufacturing approach is the integration of post-annealing processes. Annealing restores the magnetic properties of CRGO steel affected during cutting and handling. Through controlled heating cycles in a nitrogen-based atmosphere, we ensure that the laminations regain their low-loss characteristics and high magnetic induction levels. This meticulous restoration process allows transformer manufacturers to achieve greater efficiency and improved performance consistency across their product lines.
CRGO laminations produced by Rasquinha Transcore Electricals Pvt Ltd are available in a wide range of configurations, including EI laminations, step-lap mitred laminations, toroidal laminations, and customized designs tailored to customer specifications. Each lamination set is deburred, cleaned, and packaged with care to uphold our commitment to quality and reliability.
In a rapidly evolving electrical landscape, energy-saving materials and precision engineering have become mandatory. Rasquinha Transcore Electricals Pvt Ltd remains dedicated to supporting the transformer industry with world-class CRGO lamination solutions that meet international standards while addressing the growing need for sustainability and performance. With a focus on innovation, accuracy, and customer satisfaction, we continue to power the progress of industries, utilities, and infrastructure across India and beyond.
