Polyimide film insulated aluminium wire
Polyimide film insulated aluminium wire is a type of winding wire made by electric round aluminum rod which drawn by dies with special size, then over coated with enamel repetitiously.Enamelled
Round Aluminum Wire is a fundamental part of a winding in every electrical machine or apparatus. Compared to fibrous insulations, enamelled aluminium wire offers a favourable space
saving factor together with a high level of breakdown voltage. The main application of Enamelled Enamelled Aluminium wire is in winding of Motor and Transformers.

The advantages of Enamelled round aluminum wire :
1. Compared with the copper enameled wire, enameled aluminum wire is easier to winding, also there is a solid oxide film on the surface of enameled aluminum wire, which make it has a good insulating effect, a long life.
2. Due to the good insulating effect of aluminum film layer, it's heatresistant temperature can be 20 degrees higher than the copper wire;
3. Thegreatest benefit of using aluminum is that it is 1/3 lighter than copper which significantly lower the production costs, second it can attach to the solids easily, and third it can also reduce the freight and transportation during the operation.
Features of Enameled Round Aluminum Wire :
Low density allows coil weight reduction
Rapid heat dissipation
High cut through
Excellent heat shock
Perfect breakdown voltage
High heat resistance
Good solvent resistance
