Electrical breakdown of high-temperature insulation materials can be prevented by using thermoplastic Polyimide, TPI. This polymer can be extrusion-coated as other polymers, but AURUM®, TPI reduces electrical and magnetic losses. AURUM® has the highest Tg of any commercially available Thermoplastic, 473°F (245°C) and its insulation performance especially at temperatures above 302°F (150°C) beats any other known insulation.
As the automobile sector transitions to electric vehicles, new polymers that offer higher electrical and thermal properties are used. For better system integration, weight-reduction and downsizing in higher-volt systems, for faster charging and longer charging distances, electrical breakdown must be prevented by high-temperature insulation materials. AURUM® reduces electrical and magnetic losses with a high comparative tracking index (CTI) > 600 volts.
TPI coated magnet wires are a suitable choice for high-voltage applications (800V and above). Here are some key characteristics of AURUM® coated magnet wires for high-voltage mobility applications:
• High-Temperature Resistance: Capable of withstanding elevated temperatures in general and best-in class performance near welding-spots.
• Thermal Stability: Provide thermal stability over a wide temperature range, ensuring the integrity of the insulation even well above 302°F (150°C) continuously.
• Electrical Insulation: electrical breakdown and ensure the safety and reliability of the system.
• Flexibility:
• Chemical Resistance:
• High Dielectric Strength:
• Lightweight: AURUM® coated magnet wires are lightweight because even 30%
less volume insulates better than other, commonly used materials.
AURUM® is a semicrystalline TPI suitable for powder-coating, injection molding and extrusion coating, with highest-in-class glass transition temperature.
Extrusion processing AURUM® for wire insulation is highly economical.
