Polyester imine aluminum enameled wire is a type of wire mainly used for winding electrical equipment such as motors and transformers. The characteristic of aluminum enameled wire is that its conductor is made of aluminum and coated with one or more layers of polyester imine paint as insulation material on its surface. Polyester imine paint has excellent heat resistance, mechanical strength, and good chemical stability, including solvent resistance and refrigerant resistance, which enables polyester imine aluminum enameled wires to maintain good electrical and physical properties at high working temperatures and special environments. It is suitable for applications that have high requirements for the heat resistance level and overall performance of insulation materials.
