Electrical flat copper wire and flat aluminum wire

The electrical flat copper wire is the conductor extruded or drawn from the oxygen-free copper rod through the mold of certain specifications. The electrical flat copper wire can be taken as the finished product for use, and can also be an in-progress product, which is widely applied for winding of the motor, transformer, reactor and other similar electrical equipment.

The electrical aluminum flat wire is the conductor formed through continuous extrusion from the oil-free electrical round aluminum rod with the mold of certain specifications, and is widely applied for the winding of the motor, transformer, electric welding machine and other similar electrical equipment.
