Wholesale Enamelled Flat Wire Manufacturers, Supplier

Enameled rectangular wire is an enamelled rectangular conductor with an R Angle. It is described by the narrow edge value of the conductor, the wide edge value of the conductor, the heat resistance grade of the paint film and the thickness and type of the paint film. Conductors can be copper or aluminum. Compared with round wire, rectangular wire has incomparable advantages and characteristics and is used in many fields.

Frequently Asked Questions
Q: What is the difference between different thermal classes of enameled winding wires?
The thermal class (e.g., 130, 155, 180, 200) represents the maximum continuous operating temperature (in degrees Celsius) that the wire insulation can withstand for a standard lifetime without degrading. Higher classes offer better heat resistance.
Q: Why choose rectangular winding wires over round ones?
Rectangular winding wires provide a higher space factor in coils compared to round wires, allowing for more compact designs, lower electrical resistance, better heat dissipation, and higher efficiency in motors and transformers.
Q: What are the advantages of using aluminum rectangular winding wires?
Aluminum rectangular wires are significantly lighter and more cost-effective than copper. They are ideal for applications where weight reduction is critical, such as in automotive components and large industrial transformers.
Q: What insulation materials are used in Class 200 winding wires?
Class 200 enameled wires utilize a composite insulation structure, typically consisting of a Polyester-imide base coat and a Polyamide-imide (or Acid-imide) top coat. This combination offers excellent thermal stability, chemical resistance, and mechanical strength.
Q: What are the typical applications of Acetal enameled rectangular wires?
Acetal enameled wires (Class 120/105) exhibit outstanding mechanical toughness and resistance to transformer oils, making them particularly suitable for oil-immersed transformers and heavy-duty mechanical winding processes.
