CRGO 0.27mm Semi Jumbo Secondary Oily Sheets

The CRGO 0.27mm Semi Jumbo Secondary Oily Sheets are a versatile mid-format offering bridging the gap between regular sheets and full jumbo lengths. At 1,000mm to 2,000mm in length, these sheets are ideal for medium-capacity transformer cores where longer laminations improve stacking efficiency without requiring the full jumbo format.
Classified as secondary due to surplus inventory or minor handling conditions — not material defects — these sheets retain their original 0.27mm thickness and M4 Grade magnetic properties. The oily surface treatment provides reliable corrosion protection, while their secondary classification presents a compelling cost advantage for budget-conscious manufacturers. Well-suited for step-lap and butt-lap core configurations in medium power and distribution transformers.
