The structure of enameled wire is very simple, consisting of conductor and insulating layer. Because of its high dielectric strength, small footprint and good heat dissipation, it is widely used as a coil winding in motors and transformers.
Generally speaking, UL certified enameled wire needs to do four tests: Thermal Aging Test (Full Thermal Aging Test or One Temperature Thermal Aging Test) Dielectric Strength Test Elongation and Heat Shock Test Infrared Analysis – IR
