lt is our great pleasure to express our deep gratitude for your interest to Yantai Dong Shan.

We have represented the national transformer industries for 30 years.
2001 years , we had started in producing copper & aluminium magnet wires and providing them for the electronic and telecommunication industries home and abroad.

The reality is that the existing copper magnet wire has been replaced by an aluminium magnet wire owing to the rapid growth of basic materials industries. As the aluminium is three times lighter than a copper, the aluminium products are not only lighter but also friendly to the environment. For this reason, it will help solve the environmental problem regulated by the world governments and lower the production cost.

and raw materials as like copper has been climb so to be improve the problems
our company will prepare the conducter instead of copper materials,that is CCAW(Copper clad aluminun magnet wire).CCAW can use like copper and aluminum conductor and the characteristic outstanding more than the aluminum conductor.

Now, we will always devote ourselves to a new research and development and do our best to become the best company in the world transformer and aluminium magnet wire industries. we should appreciate whatever comments you may have and assure you that we shall serve you to the best of our ability.
