Avoiding Oxidation and Waste in Aluminum Transformer Strip
How to Prevent Oxidation and Energy Loss in Transformer Aluminum Strips
Transformer aluminum strips, particularly alloys like 1350, 1060, and 1070, are widely used for electrical windings and coils. However, two critical issues must be addressed to maintain quality and efficiency: oxidation and electrical loss.
How to Prevent Oxidation
✅ Use Anti-Oxidation Coated Aluminum
- Choose aluminum strips with anti-oxidation coating (such as fluorocarbon film or oil film)
- Essential for humid or coastal environments like Brazil, Ecuador, and Colombia
✅ Adopt Vacuum Packaging with Moisture Protection
- Use vacuum-sealed packaging with desiccants, moisture-proof paper, and fumigation pallets
- Protects aluminum strip surface during long-distance sea shipping
✅ Store in a Dry, Ventilated Warehouse
- Recommended humidity level: below 60%
- Keep strips away from direct sunlight or condensation
How to Reduce Electrical Loss
✅ Ensure Surface Cleanliness
- Aluminum strips must be free from oil, oxide layers, and scratches
- Use precise slitting machines to maintain edge quality
✅ Use High-Conductivity Alloys
- Opt for electrical-grade aluminum like 1350-O or 1060-O
- High purity (>99.5%) and conductivity (>61% IACS)
✅ Apply Precision Winding
- Utilize automatic winding machines to reduce air gaps
- Combine with high-quality insulation paper to improve dielectric strength
✅ Request Quality Certifications
- Ensure suppliers provide ISO 9001, SGS, and RoHS certifications
- Ask for conductivity and mechanical test reports
Export Tips for South American Clients
| Common Issue | Recommended Solution |
|---|---|
| Oxidation during shipping | Anti-oxidation oil + vacuum packaging |
| High humidity in storage | Use desiccants and sealed wooden crates |
| High energy loss | Use 1350-O strips + precision winding |
| Product complaints | Include COA + third-party test report |
