With the development of science and technology, the improvement of insulation materials for motors and electrical appliances, and the improvement of insulation technology, the requirements for the heat resistance of insulating materials have become more and more severe.

The enameled aluminum round wire produced by Henan Signi Aluminum has high product yield, high temperature resistance, refrigerant resistance, good surface quality and good thermal performance. Its structural feature is that a primer layer, an intermediate layer, and a surface insulation layer are sequentially arranged on the surface of the aluminum round conductor. The primer layer is an epoxy resin layer, and the intermediate layer is a high-temperature polyester layer, a polyester imine paint layer, or a modified layer. In any one of the polyester resin layers, the surface insulation layer is a polyamideimide paint layer.


 
The production of enameled aluminum round wire includes the following steps: 1) the aluminum conductor is stretched on a wire drawing machine to be drawn into an aluminum round conductor, 2) the aluminum round conductor is put through a washing tank for cleaning, and 3) is coated with epoxy Lacquer, 4) coated with high-temperature polyester paint, polyesterimine paint or modified polyester resin paint, 5) coated with polyamideimide paint.
 
Executive standard: GB / T23312.4-2009 Part 4 155/180/200/220 polyester enamelled aluminum round wire
Grade: 155, 180, 200, 220
Specification range: Φ0.15 ～ 1.20mm
 
roduct features and uses: This enameled aluminum round wire has high mechanical strength, and has good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance. It is widely used in various motors, electrical appliances, meters, telecommunications equipment and home appliances; The weakness is poor thermal shock resistance and low moisture resistance.
