copper magnet wire is sometimes called winding wire or enameled wire. Enameled round wire is copper or aluminum wire with a thin layer of insulating coating, wound into a coil. Magnet wires are the main components of transformers, inductors, motors and other electrical equipment. Sam Dong is the world's leading supplier of enameled round wires used in electrical appliances, automobiles, power generation and power distribution.

The insulating layer or outer coating used on the enameled round wire is a polymer film (varnish) made of various resins (usually polyester, polyglass or polyamide), which can form a strong and continuous protection for the wire Layer and allow multiple windings in the coil without short circuit. Various types of varnishes produce different characteristics or characteristics, such as:

High fever index (AI)
Abrasion resistance (NY)
Self-adhesive (SB)
Self-lubricating (SL)
The enameled round wire meets the temperature class of 105 °C to 240 °C, and can guarantee a service life of 20,000 hours at the rated temperature. Magnet wires come in various sizes and shapes, such as rectangles, squares, and circles. Enameled wire with a thermoplastic layer that bonds the coils together is used to create self-supporting coils, eliminating the need for spools and adapting to tight spaces in various electronic applications.

The electromagnetic coil converts electrical energy into an electromagnetic field. This facilitates various functions, such as increasing the voltage in the transformer, generating sound in headphones and speakers, powering the motor, providing volume control, positioning the transducer, and other resistor functions.
