Xinyu Copper Winding Wire structure in the wire and cable is the most simple, but due to the composition of the material is not the same, with different characteristics, so the use is not the same. In order to facilitate selection of suitable varieties from a wide variety of enamelled wire, the enamelled wires must be systematically categorized for the purpose of distinguishing their commonality and individuality and finding their regularity.
Xinyu Copper Winding Wire can be classified according to conductor material, film material, wire shape and insulation thickness, etc.:
According to conductor materials to points: then there are copper, aluminum, alloy (manganese copper, Hong Tong, Ni-Cr, etc.) and bimetallic (silver plated copper, nickel plated copper), copper winding wire.
According to the paint material points: there are pure polyester, acetal, oily, polyurethane, polyimide, polyester imide and polyamideimide and other copper winding wire and its two lacquer composite copper winding wire. According to the wire shape to points, there are round, flat enameled wire.
The name of an enamelled wire should include the above four categories. For example, the current mass-produced QZ-2-type polyester copper winding wire full name should be thick insulated polyester enamelled round copper wire with thin insulated polyester enamelled round copper wire, thick insulated polyester enamelled round aluminum wire, thin insulating polyester paint Round aluminum line phase distinction.
