Class 155 Modified Polyester Enamelled Aluminium Round Wire is a type of magnet wire made from high-purity aluminium conductor coated with modified polyester insulating varnish. The wire is produced through multiple coating and high-temperature curing processes. With a thermal class rating of 155°C (Class 155), it offers excellent electrical insulation, heat resistance, and mechanical performance, making it widely used in motors, transformers, and various electrical winding equipment.
Excellent Heat Resistance
This wire can operate continuously in environments up to 155°C and provides reliable thermal aging resistance for medium- and high-temperature applications.
Reliable Electrical Insulation
The modified polyester enamel coating offers high dielectric strength and insulation performance, helping improve the safety and reliability of electrical windings.
Lightweight
Compared with copper wire, aluminium wire has a lower density, which helps reduce the overall weight of electrical equipment and is especially suitable for lightweight applications.
Good Processing Performance
The wire features good flexibility, strong adhesion, and abrasion resistance, making it suitable for high-speed winding and automated manufacturing processes.
Cost-Effective Solution
Compared with enamelled copper wire, enamelled aluminium wire can significantly reduce material costs while still meeting electrical design requirements.
