Ultra-fine rectangular enameled copper wire refers to a type of wire that is extremely thin and has a rectangular cross-section. It is commonly used in applications that require high electrical conductivity and space-saving design.

Here are some production characteristics of ultra-fine rectangular enameled copper wire:
Size: Ultra-fine rectangular enameled copper wire is typically produced in sizes ranging from 0.02 mm x 0.04 mm to 0.2 mm x 0.5 mm, although these dimensions can vary depending on specific requirements.

Conductor Material: The conductor material is copper, which is known for its excellent electrical conductivity. Copper wire is preferred in many applications due to its low resistance and high efficiency.

Insulation: The wire is coated with a thin layer of enamel insulation to provide electrical isolation and protect against short circuits. The insulation material used is usually a synthetic resin such as polyurethane (PU), polyamide (nylon), or polyester.

Uniformity: The production process aims to achieve uniformity in terms of conductor size, shape, and insulation thickness. This ensures consistent electrical properties and mechanical performance throughout the wire length.

Precision Rolling: The wire is typically produced through precision rolling, where the copper is processed to achieve the desired rectangular shape and size. The rolling process involves multiple passes through calibrated rollers to gradually reduce the wire dimensions while maintaining its integrity.

Enameling: Once the wire is shaped, it undergoes an enameling process. The enamel coating is applied using methods such as dipping, spraying, or electrostatic deposition. The wire is then passed through an oven to cure and bond the enamel, forming a solid insulation layer.

Quality Control: Stringent quality control measures are implemented during production to ensure the wire meets specified standards. This may include tests for insulation thickness, adhesion, resistance, and other electrical properties.

Packaging: After production,ultra-fine rectangular enameled copper wire is typically wound onto spools or bobbins for convenient storage and transportation. The packaging process ensures that the wire remains protected and organized until it is ready for use.

It's important to note that specific production characteristics may vary depending on the manufacturer, intended application, and any custom requirements.
