Features & Advantages:

Low Cost: making it a good choice for applications where weight and cost are important considerations.
Mechanical Properties: Enameled aluminum wire is designed to be flexible and durable, able to withstand winding and bending during installation and operation.
Corrosion Resistance: The enamel coating helps protect the aluminum wire from corrosion, extending its lifespan in various environments.
