Class 240 High-Temperature Enameled Aluminum Round Wire – Aromatic Polyimide Insulation, Lightweight Alternative for Extreme Environments
QYL-240 is a premium aromatic polyimide enameled aluminum round wire offering the highest thermal class available in the industry – 240°C. This wire is engineered for mission-critical applications where weight reduction is as important as thermal reliability.
Aluminum conductors provide a significant weight advantage – approximately one-third the weight of copper – making QYL-240 the ideal choice for aerospace, electric vehicles, and other applications where every gram matters. The aromatic polyimide insulation provides exceptional resistance to thermal degradation, oxidation, radiation, and aggressive chemicals.
With a cut-through temperature of 450°C and heat shock resistance up to 260°C, QYL-240 delivers the same high-temperature performance as its copper counterpart (QY-240) while offering substantial weight savings for lightweight motor designs.
Key Features & Benefits
Highest continuous operating temperature – 240°C, with cut-through at 450°C and heat shock at 260°C.
Exceptional resistance to thermal aging, radiation, oxidation, and chemicals.
Approximately one-third the weight of copper – ideal for weight-sensitive applications like aerospace and EV motors.
Available from 0.14 mm to 1.20 mm to suit various winding specifications.
Maintains dielectric strength and insulation resistance at extreme temperatures.
Manufactured to GB/T 6109.22, IEC 60317-46, and IATF 16949 standards.
