200 grades of higher in the uniformity requirement of its thermal impact, narrow side breakdown voltage after bending and paint film, conventional compound enamel-covers
Copper strap wire its it is many adopt heat-resistant polyester for priming paint, poly- phthalein amine phenol imines is finish paint, and its film thickness is 1 grade, its temperature resistant grade height,
Paint film cracking is produced after chemical-resistance is excellent, but its narrow side carries out 4b bendings easily, breakdown voltage only has 1000V or so,
After 200-250 DEG C of baking 30 minutes, breakdown voltage only has 800V-1OOOV, and the population deviation scope of film thickness is big, attachment
The relatively low, thickness of property is also uneven.Its processing bare copper flat wire is produced using drawing process, and surface easily produces burr, passeris montani saturati skin etc. and lacks
Fall into, painted with felt method, it is impossible to using high-viscosity insullac, consumption solvent is more, and japanning felt is burnt by lower fire door high temperature
Roasting, the easy ageing hardening of felt, service life are short, and production cost is high, and felt method painting operations skill set requirements are high, it is difficult to ensure that
The concordance of product quality.
Utility model content
For the problems referred to above, this utility model provides a kind of Inverter fed motor compound enameled sheet wire, its thermal shock resistance properties and electrically
Performance is good, and after narrow side carries out 4b bendings, breakdown voltage can be maintained at the effect before not bending, and greatly improve the resistance to of enameling copper strap wire
The prescription of voltage.
To reach above-mentioned purpose, embodiment of the present utility model is adopted the following technical scheme that：
A kind of Inverter fed motor is combined enameled sheet wire, including the copper conductor, polyimide film layer, cloud that set gradually from the inside to the outside
Master tape layer and glass fiber layer, are coated with the first Inverter fed motor layer, the polyamides between the copper conductor and polyimide film layer
The second Inverter fed motor layer is coated between imines thin layer and Muscovitum belt, between the Muscovitum belt and glass fiber layer, is coated with
Three Inverter fed motor layers.
