Products Enamelled Copper Wire
Enamelled Copper Wire
ETP-grade copper with polyester, polyesterimide or amide-imide covering for motors, generators and transformers.
Our core product. Electrolytic tough-pitch copper of 99.99% purity is drawn to size, annealed in a controlled atmosphere and coated on our European and Chinese enamelling lines with the covering your winding calls for: polyester (Grade 1, 2 or 3), polyesterimide with a polyamide-imide overcoat for high thermal margins, or self-bonding coats where the coil must hold its own shape.
Each gauge is held to the covering thicknesses published in IS 13730 and IEC 60317 and checked by non-contact micrometers before the spool leaves the line. Elongation, springback, breakdown voltage and pinhole counts are logged for every batch.
