Grade 180 Polyester Imide Enameled Aluminum Round and Flat Wire

Product Introduction

Grade 180 Polyester Imide Enameled Aluminum Round and Flat Wire is a type of high-performance magnet wire manufactured with high-purity aluminum conductors coated with polyester imide insulating enamel. With a thermal class rating of 180°C (Class 180), the product provides excellent heat resistance, electrical insulation performance, and mechanical strength, making it suitable for medium- and high-temperature electrical applications.
Compared with conventional polyester enamelled wire, polyester imide enamel offers improved thermal stability, better chemical resistance, and enhanced electrical reliability, making it widely used in motors, transformers, generators, and new energy equipment.

Product Features

Excellent Heat Resistance
The wire can operate continuously at temperatures up to 180°C and provides reliable thermal aging resistance for high-temperature electrical systems.
Reliable Electrical Insulation
The polyester imide enamel coating offers high dielectric strength, excellent breakdown resistance, and stable insulation performance under demanding operating conditions.
Good Mechanical Performance
The product has strong enamel adhesion, good flexibility, and abrasion resistance, making it suitable for high-speed winding and automated production.
Lightweight Design
Using aluminum conductors helps reduce the overall weight of electrical equipment, especially for applications requiring lightweight structures.
Good Chemical Resistance
The enamel layer provides good resistance to oils, solvents, refrigerants, and chemical corrosion, improving long-term durability.
Cost-Effective Solution
Compared with copper magnet wire, enamelled aluminum wire offers significant material cost advantages while maintaining reliable electrical performance.
