Case Studies

CRGO electrical steel coils being loaded at port for African distribution transformer projects

35 Tons of CRGO Electrical Steel Coils for African Distribution Transformer Projects

Core Key Points A representative distribution-transformer order specifies standard CRGO, core loss 0.90-1.10 W/kg, magnetic induction 1.78-1.88T, thickness 0.27-0.35mm. The cost-efficient tier of CRGO — right for grid infrastructure builds where absolute lowest loss matters less than on a power transformer. Port congestion across Africa's major gateways varies sharply. Mombasa averaged ~5.33 days of vessel waiting time as of June ...

Lamination Stacking Factor Explained: Why It Affects Transformer Core Efficiency

Key Takeaways Stacking factor is the ratio of actual magnetic steel volume to total core volume in a laminated stack. It's never 100% — coating and surface irregularities always take up some space. Typical stacking factor for coated electrical steel runs 92%-97%, depending on coating thickness, coil flatness, and thickness uniformity. Thicker insulation coatings (higher coating class) reduce interlaminar losses ...

Electrical Steel Grade Equivalents: GB vs JIS vs EN vs AISI Naming Explained

Key Takeaways Four major standards name the same electrical steel differently: GB/T 2521 (China), JIS C 2552/2553 (Japan), EN 10106/10107 (Europe), and AISI M-series (United States) — and none of them use the same code structure. Every naming system encodes the same two facts — thickness and core loss — just in a different order and format. Once you know ...
