Step-Lap CRGO Transformer Laminations
Vertical & Horizontal Step-Lap Core Manufacturer in India
Rasquinha Transcore Electricals Pvt. Ltd. is a leading manufacturer and exporter of Step-Lap CRGO Transformer Laminations in India, offering Vertical and Horizontal Step-Lap cores for distribution transformers and power transformers. Our precision-engineered CRGO laminations are designed to achieve lowest no-load losses (NLL), reduced sound levels, lower magnetizing current, and faster core assembly, meeting international transformer efficiency standards.
Vertical Step-Lap CRGO Transformer Lamination | Low-Loss Core Design
The Vertical Step-Lap CRGO Lamination, based on the proven Westinghouse step-lap design, uses a cross step-lap joint system that minimizes joint overlap and improves magnetic flux continuity. Compared to conventional lap joints, this design significantly reduces transformer losses and noise.
Vertical Step-Lap Benefits
Reduced joint overlap (3–5 mm vs 10–15 mm)
Progressive stepping across 5–7 laminations
Lower core losses and magnetizing current
Reduced transformer noise levels
Optimized CRGO steel usage
Faster and easier transformer core assembly
Horizontal Step-Lap CRGO Transformer Lamination | High-Efficiency Core
Our Horizontal Step-Lap CRGO Transformer Laminations are engineered for advanced magnetic performance and simplified transformer manufacturing. The stacked core design uses precisely aligned step-lap joints between yoke and leg members, ensuring uniform flux distribution and reduced no-load losses.
Horizontal Step-Lap Core Advantages
Reduced no-load losses (NLL)
Lower sound levels in transformers
Simplified top yoke insertion
Faster core assembly time
Competitive manufacturing cost
