Enameled wire (enameled copper wire)


What is ECU wire?

Using refined electrolytic copper as conductor , and covered with insulating material(such as UE, PE,EI,AI) in high temperature oven. Enameled copper wire has the characteristic of high break down voltage and high strength.


Motor category

Such as all kinds of household electrical appliances (such as kitchen electrical appliances, washing machines, vacuum cleaners, motor and other high-speed motor)

Fan motor

Variety of micro motor

Variety of pump motor

Variety of automotive electrical appliances, etc.


Transformer category

Such as various types of high-frequency transformer

All kinds of ordinary power frequency transformer

Various types of chargers, etc.


Electromagnetic induction coil category

Such as rectifier

All kinds of loop inductance coil, choke

Various types of electromagnetic induction disk, etc.


1. The most widely used enameled wire products, which are widely used in all kinds of electronic, motor, transformer coil.

2. High conductivity compared to aluminum.

3. High strength, not easy to elongate during the winding process.

4. High stability of the product
