What Our Clients Say

Testimonials

Industrial Motor Manufacturer

Daniel Whitfield

"We use these Enamelled Copper Wires for our 200°C class industrial motor windings. The polyimide insulation holds up well under continuous thermal load, and dielectric strength consistently exceeds 7000 VAC in our incoming inspection."

Chief Winding Engineer

Алексей Романов

«Мы закупаем эмалированные медные провода для силовых трансформаторов. Провод диаметром от 0,05 до 5,0 мм с изоляцией класса 180 стабильно выдерживает термоудар 220°C, а удлинение не менее 35% позволяет наматывать плотные катушки без разрывов эмали.»

Wind Turbine Generator Manufacturer

Slivina

"These Enamelled Copper Wires are used in our wind turbine generator windings where partial discharge resistance is critical. The 200°C class wire with corona-resistant coating has performed reliably under high-frequency PWM conditions, and the flat wire dimensions are held within tight tolerances, which keeps our winding factor consistent."

Electromagnetic Component Distributor

Fernanda Oliveira

"Distribuímos esses Enamelled Copper Wires para fabricantes de transformadores e motores no Brasil. O que mais nos tranquiliza é a conformidade: certificação UL, RoHS e IEC 60317 em cada lote, com relatórios de inspeção completos. Isso nos permite atender rapidamente às auditorias dos nossos clientes e manter prazos curtos."

Our Inquiry Service

Enameled copper wire consists of a pure copper core coated with a thin layer of insulation (typically polyesterimide or polyamide-imide). The enamel coating acts as an electrical insulator while maintaining flexibility, allowing the wire to be tightly wound into coils without short-circuiting. This insulation also provides:

High-temperature resistance(up to 220°C for industrial motors)

Corona resistance for high-voltage applications like wind turbine generators

Direct solderability without stripping the coating, ideal for circuit board repairs

Its core advantage lies in balancing conductivity (coppe’s low resistance) and durability, making it essential for transformers, motors, and electromagnetics

Enameled copper wire is versatile across industries due to its compact design and thermal stability:

Electronics & Repair: Used in fly wires for motherboard repairs (0.1mm diameter), sensors, and relays.

Energy Systems: Wind turbine generator windings (corona-resistant), transformer coils (compact power efficiency).

Industrial Machinery: Electric vehicle traction motors, industrial motors (180–220°C environments), and automotive wiring harnesses.

DIY & Crafts:  Jewelry making and model building (thin gauges like 0.04–0.31mm).
Applications prioritize minimal energy loss, heat dissipation, and space-saving designs.

Current Requirements:​​

Thicker wires (e.g., 0.5–2.0mm) handle higher currents in motors/transformers.

Thin gauges (0.04–0.2mm) suit low-current electronics like sensors.

Temperature Rating:​​

Standard polyesterimide: 155°C (e.g., household appliances).

Polyamide-imide: 220°C (industrial motors).

Insulation Type:​​

Use polyamide-overcoated wires for harsh environments (abrasion resistance).
Always verify specifications (e.g., IEC 60317 standards) and consult wire gauge calculators for precision.
