Rongdawire supplies enameled copper winding wire made from 99.99% pure electrolytic copper, coated with thermal-grade insulation suitable for high-temperature applications. The wire is manufactured in standard SWG and AWG sizes, with insulation systems meeting IEC 60317 and NEMA MW 1000 standards. It is used in transformers, motors, and inductors where high conductivity and thermal stability are critical.
The enamel coating is applied in multiple layers and cured under controlled conditions to ensure adhesion and dielectric strength. Common insulation types include polyesterimide and polyamide-imide, rated for Class H (180°C) operation. The wire exhibits low elongation under tension and maintains flexibility during winding, reducing breakage rates in automated coil winding machines.
Buyers include manufacturers of electric motors, power transformers, and aerospace components. The product is typically sold in spools of 10kg to 50kg, with custom spool sizes available. Packaging is in moisture-resistant cartons with desiccant. Delivery is usually FOB Xuancheng or CIF Shanghai. Buyers must specify the required AWG size, insulation class, and coating thickness in their purchase order.

Before ordering, confirm the exact AWG size, insulation class, and enamel type match your application. Request a sample for dielectric, thermal, and mechanical testing. Do not accept wire without a material certificate showing compliance with IEC or NEMA standards. Verify the copper purity via a spectrometer report if used in high-efficiency motors.
Logistics are typically FOB Xuancheng or CIF Shanghai. Lead time ranges from 15 to 30 days depending on order size. Payment terms are commonly 50% advance, 50% against BL copy. Incoterms must be clearly defined. Buyers should ensure the supplier provides export documentation, including a commercial invoice and packing list with batch numbers.
Quality checks should include a visual inspection for coating defects, a dielectric test on a sample, and a diameter measurement using a micrometer. Request a batch-specific test report for insulation thickness and tensile strength. For large orders, consider a pre-shipment inspection by SGS or Bureau Veritas to verify compliance with technical specifications.
