Square enameled aluminum wire is a type of magnet wire that features a square cross-section and is coated with an insulating enamel layer. It is widely used in electrical applications where efficient winding, high conductivity, and lightweight properties are required.
Square Enameled Aluminum Wire Application
■ 120 degree flat enamelled wire for oil-immersed transformer
■ 130, 155, 180 degree flat enamelled wire are widely used in all kinds of magnet coil
■ 200 degree flat enamelled wire works constantly in high temperature
■ 240 degree flat enamelled wire for magnet coils of aviation, military and marine application
Key Features:
✅ Lightweight – About one-third the weight of copper, making it ideal for applications where weight reduction is important.
✅ Good Conductivity – Although aluminum has lower conductivity than copper, its weight-to-conductivity ratio makes it an efficient alternative.
✅ Space-Saving Design – The square shape allows for tighter coil packing compared to round wire, improving space utilization and increasing efficiency.
✅ Heat Resistance – Available in different enamel coatings to withstand various temperature ranges, typically up to 220°C.
✅ Oxidation Resistance – The enamel coating prevents oxidation, which is a common issue with bare aluminum wire.
