Enamelled copper wire, also known as magnet wire or winding wire, is a type of copper wire that has a thin insulating layer of enamel or varnish applied to its surface. This insulating layer is typically made of a synthetic polymer material such as polyurethane, polyester, or polyimide. The purpose of the enamel coating is to provide electrical insulation while allowing the wire to carry an electrical current.
Enamelled copper wire comes in various gauges (diameters) and insulation types, allowing engineers and manufacturers to choose the appropriate wire for their specific needs. The enamel insulation is resistant to heat, moisture, and many chemicals, making it a reliable choice for applications where electrical insulation is crucial.
Enamelled copper wire is commonly used in a variety of electrical and electronic applications, including:
