The aluminum enameled wire comprises aluminum round conductor which comprises a primer layer, a middle layer and a surface insulation layer, wherein the primer layer is an epoxy resin layer, the middle layer is a high temperature polyester layer, a polyester inferior amine paint layer or a modified polyester resin layer and the surface insulation layer is polyamide-imide paint layer. 

How to produce the enameled round aluminum wire?
1) aluminium conductor is placed on the wire drawing machine draw greatly, in draw repeatedly stretch after, be drawn into the naked aluminium round conductor of 0.700mm～2.500mm,
2) aluminium round conductor unwrapping wire passes the cleaning of wash water groove, and per minute cleans the aluminium round conductor 10～20 times, and 400～600 ℃ of continuous annealing temperature are cleaned through supercooling again, and cooling water is an ionized water, and the ionized water conductivity is 10～20 μ s/cm, 60～80 ℃ of cooling water temperatures,
3) coat epoxy resin coating, japanning 1～10 road, every japanning is once cured once,
4) coat high-temperature polyester lacquer, polyester-imide lacquer or modified polyester resin lacquer, japanning 3～9 roads, every japanning is once cured once,
5) be coated with the polyamidoimide lacquer, japanning 2～5 roads, every japanning is once cured once,
6) the conductor lines footpath more than in each step and the product of conductor speed, just the value of enamelled wire DV is 22～40, the solvent evaporation temperature is 280～350 ℃, the film curing temperature is 390～500 ℃, film thickness is 0.035～0.090mm, apply lubricating oil, the online detection of instrument after testing, finished product take-up promptly get the aluminium enamel-covered wire that 200 grades and above high-temperature polyester or polyester-imide composite polyamide acid imide coat with lacquer.
The conductor lines here directly is meant the diameter before the japanning, because upper base enamelled coating lacquer, intermediate layer lacquer, surface insulation layer lacquer be for carrying out simultaneously, it is consistent that speed and temperature are controlled.

Enameled round aluminum wire has the features of high temperature resistance, coolant resistance, good surface quality and optimal thermal performance.
