Abstract

The utility model discloses a kind of high intensity self-adhering-type enamel-covered wire, it is characterized in that, including metal core and outer coat, the metal wire core outer surface is outer coat, and the outer coat is followed successively by polyethylene layer, Inverter fed motor layer, polyamidoimide paint film, high heat transfer paint film, self-adhesion paint film from inside to outside.The intensity of high frequency enamel-covered wire is improved by the utility model, there is heat sinking function and self-adhesion function, easy to use, long lifespan.

Description

A kind of high intensity self-adhering-type enamel-covered wire

Technical field

The utility model belongs to enamel-covered wire technical field, more particularly to a kind of high intensity self-adhering-type enamel-covered wire.

Background technology

With developing rapidly for variable-frequency control technique, the application field of variable-frequency motor is more and more extensive, and especially exchange becomes Frequency motor, alternating-current variable frequency motor using when electricity be impulse wave, waveform has a towering spike, and with the precipitous rise time and High frequency.Conventional variety enamel-covered wire is with this alternating current generator, because of the anti-high frequency of this enamel-covered wire and momentary pulse spike The ability of voltage is weak, and enamel-cover line winding is easy to that breakdown between adjacent turns phenomenon occurs, and motor service life is shortened, in this situation Under, the Inverter fed motor enamel-covered wire of variable-frequency motor is urgently developed.The anti-corona performance of enamel-covered wire in the market is low, tensile resistance Weak, service life is short.

Utility model content

The purpose of this utility model is to provide a kind of intensity height have tack, the high intensity self-adhesion of service life length Type enamel-covered wire.

In order to solve the above technical problems, the utility model provides a kind of high intensity self-adhering-type enamel-covered wire, it is characterised in that bag Metal core and outer coat are included, the metal wire core outer surface is outer coat, and the outer coat is followed successively by from inside to outside Polyethylene layer, Inverter fed motor layer, polyamidoimide paint film, high heat transfer paint film, self-adhesion paint film.

Improvement of the present utility model has：In order that enamel-covered wire plays more preferable insulation effect, the thickness of the polyethylene is 0.50-0.55mm；

In order that enamel-covered wire plays more preferable Inverter fed motor effect, the thickness of the Inverter fed motor is 0.40-0.44mm.

In order that enamel-covered wire plays more preferable insulation effect, the thickness of the polyamidoimide paint film is 0.33-0.35；

In order that enamel-covered wire plays more preferable radiating effect, the thickness of the high heat transfer paint film is 0.30-0.35mm；

In order that enamel-covered wire plays more preferable self-adhesion effect, the thickness of the self-adhesion paint film is 0.35-0.40mm；

In order that enamel-covered wire plays more preferable conductive effect, the metal of the metal core is aluminium.

The beneficial effects of the utility model are：The utility model discloses a kind of high intensity self-adhering-type enamel-covered wire, outer coating Layer surface scribbles polyethylene layer, Inverter fed motor layer, polyamidoimide paint film, high heat transfer paint film, self-adhesion paint successively from inside to outside Film.Enamel-covered wire is set to reach with tack, the effect of corona resistance, tensile resistance is strong, improves service life.

Brief description of the drawings

Accompanying drawing 1 is structural section figure of the present utility model.

Label declaration：1- metal cores；2- polyethylene layers；3- Inverter fed motor layers；4- polyamidoimide paint films；5- high fevers pass Lead paint film；6- self-adhesion paint films.

Embodiment

The utility model is further described with reference to the accompanying drawings and in conjunction with the embodiments.

Referring to the drawings 1, the utility model provides a kind of straight weldering property high frequency enamel-covered wire, it is characterised in that including metal core 1 With outer coat, the outer surface of metal core 1 is outer coat, the outer coat be followed successively by from inside to outside polyethylene layer 2, Inverter fed motor layer 3, polyamidoimide paint film 4, high heat transfer paint film 5, self-adhesion paint film 6.

Inverter fed motor layer is the insulated paint with corona resisting characteristics, it is preferred that can use three-layer insulated structure, intermediate layer is The Inverter fed motor layer of the inorganic oxide filling such as titanium dioxide is admired, aluminum oxide, silica, zinc oxide, iron oxide.

Improved as the step of progress one of the present utility model, in order that enamel-covered wire plays more preferable insulation effect, the poly- second The thickness of alkene is 0.50-0.55mm；In order that enamel-covered wire plays more preferable Inverter fed motor effect, the thickness of the Inverter fed motor is 0.40-0.44mm.In order that enamel-covered wire plays more preferable insulation effect, the thickness of the polyamidoimide paint film is 0.33- 0.35；In order that enamel-covered wire plays more preferable radiating effect, the thickness of the high heat transfer paint film is 0.30-0.35mm；In order to Enamel-covered wire is set to play more preferable self-adhesion effect, the thickness of the self-adhesion paint film is 0.35-0.40mm；In order that enamel-covered wire plays more Good conductive effect, the metal of the metal core is aluminium.

Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
