Features of  polyurethane enameled copper wire :
1 It is adoped copper ribbon wires,better than round wires in terms of space factor
2 This product has very good self-bonding character apart from the properties of ployester enameled wire
3 It can be self-bonded after electric heating or solvent-bond
4 It can reduce the pollution of coil manufactory  
5 Save the power consumption and raise the benifit 
6 Feature of Copper-clad-Aluminum wire 
Copper-clad-Aluminum wire is a composite comductor with an aluminm base material.As the conductor is composed of aluminum core and copper cladding,wire characteristics lie between those of aluminum and copper.Lighter than copper wire.Highter conductivity than aluuminum wire.

Applications of  polyurethane enameled copper wire :
1 Alcohol soluble enamelled flat copper wire
   1)Moving coils
   2)Printer coils
   3)Small Motor
   4)High-class speaker
   5)Special voice coil
      etc.
 2)Alcohol soluble Enameled copper-clad-aluminum round and flat wire
   1) Voice coils
   2) Moving coils
   3) Hollow coils for motors
