Description
Technical field
It the utility model is related to a kind of enamel-covered wire, particularly insulating lacquer layer.
Background technology
At present, the transformer market scale motive force of growth in China is powerful, to find out its cause, mainly having two：First, traditional change
Depressor upgrading will expedite the emergence of the very big market share, and the superseded work of backward products can promote effectively opening for bidding
Exhibition, huge economic benefit will be apparent from；On the other hand, energy-saving, intelligent transformer research and development, manufacture, sell, make
With, safeguard and will turn into main flow, the inevitable opportunity to develop brand-new for the industrial zone of completely new product.But Domestic Transformers are with 180
Level polyester-imide ultra micro thin flat wire is applied or simple composite due to being influenceed by traditional processing technology and material price are higher using single
The mode of double enamelled coatings, the resist processing of product than relatively low, therefore heat-resisting life is not high, moisture resistant poor performance, paint film poor toughness with
And the shortcomings of anti-processing and forming lesion capability difference, as much time using can cause coil turn-to-turn short circuit.
Utility model content
The purpose of this utility model is, there is provided a kind of polyester-imide enameled sheet wire.The utility model has heat-resisting life
The characteristics of long, moisture resistance can be strong, paint film toughness and anti-processing and forming lesion capability are good.
The technical solution of the utility model：A kind of insulating lacquer layer, including copper strap wire, the outer surface of copper strap wire is successively
Provided with the first insulating barrier, Inverter fed motor layer, the second insulating barrier and waterproof layer；First insulating barrier includes 2 layers of polyester-imide enamelled coating,
And tear resistant layer is provided between 2 layers of polyester-imide enamelled coating.
In foregoing insulating lacquer layer, the polyester-imide thickness of paint layer is 0.013 to 0.017mm.
In foregoing insulating lacquer layer, the tear resistant layer is Phthalazinone poly (arylene ether nitrile) ketone (PPENK) enamelled coating, and
Tear resistant layer thickness is 0.008 to 0.012mm.
In foregoing insulating lacquer layer, the Inverter fed motor thickness degree is 0.018 to 0.022mm.
In foregoing insulating lacquer layer, second insulating barrier is polyamidoimide enamelled coating, and the second insulating barrier
Thickness is 0.018 to 0.022mm.
In foregoing insulating lacquer layer, the waterproofing layer thickness is 0.010 to 0.012mm.
Compared with prior art, the utility model uses in 2 layers of polyester-imide enamelled coating and sets Phthalazinone poly (arylene ether nitrile) ketone
(PPENK) priming paint of enamelled coating, has taken into account insulating properties and toughness.Middle anti-corona layer can improve the enamelled coating life-span, prevent enamelled coating
It is breakdown because ionizing.Finish paint includes polyamidoimide enamelled coating and waterproof layer, and polyamidoimide is a kind of with preferably wear-resisting
The insulated paint of performance, reduce the damage that enamel-covered wire is subject in following process winding.Above-mentioned enamelled coating has good heat resistance.
Therefore, the utility model has strong heat-resisting life length, moisture resistance energy, paint film toughness and anti-processing and forming lesion capability good
Feature.
