Aluminium Enameled Winding Wire or simply called Enameled Aluminium Wire is critical part in the winding of almost all the electrical machines and apparatuses. In terms of space saving, these enameled wires are much better in comparison to the fibrous insulation. Adding on, these coated wires or metal wires also have higher level of breakdown voltage. Their diameter range is 1.50 to 5.50 mm, with main application being in the winding of transformers and motors. Aluminium Enameled Winding Wire can have four types of enamel such as Polyester, Polyesterimide, Polyvinyl Acetal (PVA / PVF) and Polyesterimide (base coat) + Polyamide-imide (top coat).
