What governing standard and construction define POLYESTER-GLASS ENAMEL WIRE (IEC 60317-48 Class 200 Enamelled + Dacron/Glass-Fiber Yarn Covered Copper Winding Wire)?

POLYESTER-GLASS ENAMEL WIRE (IEC 60317-48 Class 200 Enamelled + Dacron/Glass-Fiber Yarn Covered Copper Winding Wire) is manufactured in accordance with IEC 60317-48 / NEMA MW 50-C for Up to 3.6 kV service over -40 °C to +200 °C. Its 4-layer construction comprises stranded copper conductor, polyester enamel base, polyamide-imide enamel overcoat, polyester-glass serving.

What is the minimum bending radius and installation temperature for POLYESTER-GLASS ENAMEL WIRE?

The minimum installed bending radius for POLYESTER-GLASS ENAMEL WIRE is 6 × OD across its continuous operating temperature range of -40 °C to +200 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of POLYESTER-GLASS ENAMEL WIRE arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per IEC 60317-48 / NEMA MW 50-C); (02) Polyester enamel base (Polyester enamel base (continuous layer)); (03) Polyamide-imide enamel overcoat (Polyamide-imide enamel overcoat (continuous layer)); (04) Polyester-glass serving (Polyester-glass serving high-coverage braided layer (woven structure)).

What factory test certificates are supplied with POLYESTER-GLASS ENAMEL WIRE?

Every production drum or spool of POLYESTER-GLASS ENAMEL WIRE undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per IEC 60317-48 / NEMA MW 50-C, and is delivered with an EN 10204 3.1 factory test certificate.
