Magnet wire is copper wire with a thin layer of insulation, and it is used in a variety of applications including transformers, wound coils, motors, solenoids, and instruments. Raw copper is drawn to meet specific size requirements based on National Electrical Manufacturer's Association (NEMA) standards. This magnet wire meets the NEMA MW-79-C standard for operating temperature (155°C/311°F) and insulation makeup. The insulation is made from modified Polyurethane with a polyamide overcoat, which protects the coiled wire from short-circuiting.
