In 240 grades of aromatic polyimide enamelling cuprum round line above-mentioned, the thickness of the waterproof layer is 0.04-0.06mm.
Compared with prior art, paint is improved in the outer surface of the utility model by the axial strip resist bending paint item of a circle
The counter-bending and tensile property of film, while the anti-torsion performance of the paint of the resistance to torsion item raising paint film by a circle closed curve shape,
Resist bending paint item and resistance to torsion paint item are disposed alternately at the outer surface of waterproof layer, and the paint film of the utility model is made to have preferable power
Learn performance.On the other hand, the utility model is the enamelled coating structure of multilayer, and the ductile layers therein being clipped in the middle can be carried effectively
The toughness of high paint film, can bear that temperature cycles more times bring expands with heat and contract with cold, and service life is improved, to ensure that
Heat resistance.By heat shock resistance layer, the utility model is also preferable to the resistance of thermal shock.Moreover, metal aoxidizes
Nitride layer can reduce the corona phenomenon of enameled wire as shielded layer, the strong oxidizing property gas attack paint film for preventing corona from generating；Simultaneously
Waterproof layer is then used to prevent abrasion and corrosion of the sundries to paint film during transport and use, both improves the longevity of paint film
Life.
Therefore, the utility model has the characteristics that paint film mechanical property, heat resistance and thermal shock resistance are preferable.This
Outside, the utility model also has the characteristics that with long service life.
