◎ Enameled copper wire
        (PEW, EIW, AIW, EI-AIW, SL-EI-AIW)


Magnet wires are wound like coils inside of electric. electric
equipment, which transform mechanical energy into
electric energy. into electric energy.
Necessaryfor all the equipment that needs
electricty such as heavy industry, automotive parts, home
appliances, medical equipment, and even to aerospace industry.
We are providing various enameled copper wires to meet
customer' demands.
