Enamelled copper wire, also called “Magnet Wire,” is widely used in various Electrical Applications due to its superior Electrical, Thermal and Mechanical Properties. Enameled Copper Wire are insulated by coating it with enamel of different temperature class. Enamelled Copper Wire are primarily used in three types of applications – in transformers to transform one kind of electrical energy into other kinds. Copper Enameled Winding Wire are used in motors to transform electrical energy into mechanical energy.
