Why choose Class 200 polyesterimide enameled wire?

As new energy motors develop towards high power density and high frequency, traditional Class 155 enameled wire can no longer meet the stringent working conditions. Class 200 polyesterimide enameled wire has become the preferred solution chosen by the world’s top 10 motor manufacturers due to its superior performance and outstanding performance.

Reasons for choosing Class 200 polyesterimide enameled wire

• Revolutionary breakthrough in high temperature insulation

✅200℃ continuous temperature resistance: 52,000 hours of measured life (IEC 60851 accelerated aging test), 3 times longer than the traditional Class 155 enameled wire life.

✅250℃ short-term overload: passed 100 hours of extreme test (UL 1446 standard only requires 72 hours).

✅ Thermal shock performance: remains intact under rapid temperature change conditions of -65℃~250℃ (military grade standard).

• The perfect solution for the frequency conversion era

✅Corona resistance life of 80,000 hours (10kHz PWM frequency conversion test data)

✅Partial discharge <3pC (only 1/5 of competitors at 2000V voltage)

✅Breakdown voltage 8.5kV (0.5mm wire diameter measured, 15% higher than the industry standard)

• Triple protection system

✅Mechanical protection: no cracks when the bending radius ≤ 2D (ASTM D2518 certification)

✅Chemical protection: passed 48h acid and alkali/refrigeration oil immersion test

✅Environmental protection: 100% insulation integrity after 1000h salt spray test

• Global certification system

✅UL certification file number: E468639 (200℃ Class)

✅EU CE certification: EN 60317-30 standard

✅Japanese JIS C3202 Type 2 certification
