Enameled copper wire, also called "magnet wire," is widely used all
over the world in electrical equipment.. The difference between the
enameled copper wire and regular wire is in the insulation
surrounding the wire. Normal copper wire is insulated by wrapping
it in thick rubber. Enameled copper wire is insulated by coating it
with enamel. It is primarily used in three types of applications.
It is used, in transformers to transform one kind of electrical
energy into other kinds. It is used in motors to transform
electrical energy into mechanical energy. It is also used in
generators to transform mechanical energy into electrical energy.
FEATURES AND BENEFITS
Higher thermal property
Good resistance to refrigerant and freon
Suitable for windings that are subjected to constantly high
temperature and mechanical stress
Good chemical resistanceFE
