1. Litz wire: A conductor is an electromagnetic wire that is stranded or braided by multiple independently insulated conductors. Typical applications are: high frequency inductors, transformers, inverters, fuel cells, motors, communications and IT equipment, ultrasonic equipment, sonar equipment, televisions, radio equipment, induction heating, etc.

2. Bare copper wire: It has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; it has good thermal conductivity and is often used to manufacture magnetic instruments and instruments that must be protected from magnetic interference, such as compasses, aviation instruments, etc.; plastic poles Good, easy to hot and cold pressure processing, can be made into copper materials such as pipes, rods, wires, strips, strips, plates, foils, etc. There are two kinds of pure copper products: smelted products and processed products.

3. Enameled wire: It is a main variety of winding wire. It consists of conductor and insulating layer. After the bare wire is softened by annealing, it is painted and baked many times.
