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.

Application of Xinyu copper winding wire:

Used in production of light weight, relatively high conductivity, heat
resistance and good windings, especially the transmission of high frequency
signal windings;

Used in magnet wires of high-frequency voltage devices, common transformer,
inductance coils, electromotors, household electrical and micro-motors;

Used in electrical tools, ballasts, automotive electronics, refrigerator and
air conditioner compress or motors. Such as television sets, electric stove,
microwave ovens etc.

Used in electrical appliances, communication tools, instruments,
transformers, generators,electromotors, and so on.
