The Middle East is a growing market for dry-type transformers, thanks to its infrastructure expansion and preference for fire-safe electrical systems. Aluminum strip is widely used in these transformers due to its light weight and excellent electrical properties. This guide outlines the key factors to consider when selecting aluminum strip for this region.

Common Aluminum Grades

The most popular aluminum alloys for dry-type transformer windings are:

• 1050 – High purity and excellent conductivity
• 1060 – Similar to 1050, widely used for LV/HV windings
• 1070 – Offers slightly better conductivity, used for high-efficiency designs

All are typically supplied in soft annealed (O) temper to allow easy shaping during winding.

Suitable Dimensions

Middle Eastern clients often request specific thickness and width ranges:

• Thickness: 0.20 mm to 2.0 mm
• Width: 30 mm to 650 mm
• Core ID: 150 mm or 300 mm, depending on equipment

Heat Resistance

Dry-type transformers operate at elevated temperatures. Aluminum strips must maintain stability under 155°C (Class F) or even 180°C (Class H). Proper annealing and tight tolerance control help avoid deformation or breakdown.

Surface Cleanliness & Edge Quality

For safe winding and insulation application:

• Edges should be burr-free and smooth
• Surface must be clean and free from oil, dust, or oxide

Regional Logistics and Certification

When exporting to Middle Eastern markets such as Saudi Arabia, UAE, or Oman, consider:

• GCC Conformity Marking (for some large projects)
• Proper export packaging to withstand desert conditions
• Fast and stable delivery via Jebel Ali or Dammam ports

Choosing the right aluminum strip for dry-type transformers in the Middle East involves more than just alloy and size. High-temperature performance, edge quality, and logistics preparation are equally important for a smooth and efficient supply chain.
