Enamelled Copper/Aluminum Flat Wire
Enamelled copper (aluminum) flat wire is an electromagnetic wire made of high-purity copper (or aluminum) as the conductor, rolled or drawn into a flat cross-section, coated with insulating paint and cured by baking. Suitable for winding manufacturing of various transformers, motors, reactors and other electromagnetic equipment, especially for high-power density and miniaturized electrical products. Compliant with GB/T 6109 and IEC 60317, it features high space factor and excellent heat dissipation.

Product details
Enamelled copper (aluminum) flat wire is an electromagnetic wire made of high-purity copper (or aluminum) as the conductor, rolled or drawn into a flat cross-section, coated with insulating paint and cured by baking. Suitable for winding manufacturing of various transformers, motors, reactors and other electromagnetic equipment, especially for high-power density and miniaturized electrical products. Compliant with GB/T 6109 and IEC 60317, it features high space factor and excellent heat dissipation.
Product Features
High space utilization: flat cross-section enables tight winding with 15%-25% higher filling factor than round wires, reducing equipment volume. Excellent conductivity and heat dissipation: copper (≥97%IACS)/aluminum (≥61%IACS) conductors; flat structure boosts heat dissipation, lowering temperature rise by 8-15℃ to extend life. Reliable insulation: paint layers (130℃-240℃) with oil/solvent resistance, high mechanical strength, breakdown voltage ≥60kV/mm. Strong processability: withstands bending/winding for automatic equipment; tinned copper/anti-oxidation aluminum enhance connection reliability. Material economy: aluminum flat wire (1/3 copper density) cuts cost 30%-50%, ideal for weight/cost-sensitive medium-low voltage equipment.
Product Classification
Classified by conductor material: enamelled copper flat wire (high conductivity for high-frequency, high-power equipment); enamelled aluminum flat wire (lightweight for low-voltage, high-current scenarios). By insulating paint type: polyester (130℃, general); polyimide (220℃-240℃, high-temperature resistant); polyurethane (155℃, direct solderable). By cross-sectional size: narrow side 2mm-15mm, wide side 5mm-50mm, with customizable special specifications for different windings.
After-sales Service
Technical support: cross-section selection, insulation grade matching and winding design consultation to optimize electromagnetic performance. Quality assurance: each batch with material certificate and test report, supporting third-party testing, 18-month warranty. Supply guarantee: regular specs shipped within 72 hours, customized ones delivered in 15-20 days, with national direct logistics.
