When it comes to transformer winding, edge quality of the aluminium strip is not just a detail—it’s critical. Poor edge processing can cause scratches on insulation paper, electrical discharge, or even safety hazards. That’s why we offer professional edge treatment services for all our aluminium strips.

Types of Edge Processing We Provide

• Deburred Edge – Removed sharpness and micro burrs, suitable for high-speed winding
• Round Edge – Smoothly rolled edge for maximum insulation protection
• Flat/Cut Edge – Standard straight cut, used for secondary processing

All processed edges are inspected for consistency and free from burrs, cracks, or deformation. Our precision tools ensure dimensional integrity after edge processing.

Why Edge Treatment Matters for Your Transformers

• Improves safety during winding operation
• Protects insulation layers and interlayer paper
• Enhances coil smoothness and uniformity
• Reduces manual polishing or post-treatment at your end

Product Compatibility

• Aluminium Alloys: 1060-O, 1350-O
• Thickness: 0.3 mm – 2.5 mm
• Width Range: 20 mm – 1200 mm
• Edge Type: Round / Deburred / Flat

Whether you're making oil-immersed distribution transformers or dry-type reactors, proper edge processing saves time, cost, and rework.
