Transformer core manufacturing demands accuracy in both dimension and magnetic performance. A minor deviation in coil width can result in excess scrap, inconsistent stacking, and higher losses. CRGO Narrow Width Coils address this challenge by providing material in precise widths suited to transformer lamination design, ensuring optimum utilization and magnetic efficiency from the start of the production line.
Optimized Material Utilization
Traditional wide coils often require slitting or trimming before use, which not only consumes time but also increases waste. CRGO Narrow Width Coils are pre-processed to exact lamination dimensions, minimizing offcuts and improving yield. This results in smoother workflow, better quality control, and reduced operational costs in high-volume core manufacturing.
Magnetic Performance and Grain Orientation
The strength of CRGO Narrow Width Coils lies in their highly aligned grain structure, oriented in the rolling direction of the steel. This orientation minimizes hysteresis and eddy current losses, ensuring efficient magnetic flux flow within the transformer core. The result is lower energy loss, reduced heating, and improved overall transformer performance.
Manufacturing and Operational Benefits
No Additional Slitting: Streamlined production with minimal material handling.
Uniform Lamination Widths: Enhanced stacking accuracy and reduced air gaps.
Lower Core Loss: Maintained grain orientation improves flux efficiency.
Higher Throughput: Simplified workflow and faster lamination assembly.
Material Cost Savings: Better yield from every coil.
Application in Modern Transformer Manufacturing
CRGO Narrow Width Coils are ideal for manufacturing rectangular, step-lap, and mitred laminations used in power and distribution transformers. Their consistent width and controlled surface finish support automated core cutting and assembly systems, ensuring repeatable quality and compliance with energy efficiency standards.
Conclusion
For transformer manufacturers focused on efficiency, CRGO Narrow Width Coils provide a measurable advantage reduced waste, better performance, and faster production. They represent a step forward in material optimization and play a key role in achieving both operational and energy efficiency targets.
