T2 copper strip is a widely used copper material for transformer winding because it provides a good balance of conductivity, ductility, processing performance and cost efficiency.
During transformer winding, the copper strip needs to maintain stable thickness, smooth surface and good edge quality. If the edge has burrs or sharp corners, it may damage insulation paper or insulation film, causing potential insulation failure. Therefore, low burr edge or round edge copper strip is recommended for transformer winding applications.
Our T2 copper strip is produced with precision slitting and strict inspection to ensure stable quality for transformer coil production.
T2 copper strip is widely used in:
Transformer winding
Transformer coils
Dry-type transformers
