Summary of the invention
the purpose of this utility model is, provides a kind of high-temperature resistant enamelled wire.By the thickness in monolayer forming each enamelled coating is set as non-uniform thickness, thus it is even to make enamelled wire structure have performance, and resistance to elevated temperatures is good, long service life, and adhesion property is good, puncture voltage is high, is heated evenly, and is applicable to the advantages such as high-speed winding.
the technical solution of the utility model: a kind of high-temperature resistant enamelled wire, includes circular copper wire, circular copper wire is provided with modified poly ester enamelled coating, polyester-imide enamelled coating, polyamidoimide enamelled coating and nylon enamelled coating from the inside to the outside successively; Wherein modified poly ester enamelled coating is made up of 3 layers of modified poly ester individual layer; Polyester-imide enamelled coating is made up of 9 layers of polyester-imide individual layer; Polyamidoimide enamelled coating is made up of 8 strata amide imide individual layers; Nylon enamelled coating is made up of 4 layers of nylon individual layer, and each thickness in monolayer is all identical, and thickness is: 0.0030-0.0032mm.
aforesaid high-temperature resistant enamelled wire, described thickness in monolayer is 0.0031mm.
the beneficial effects of the utility model: compared with prior art, the utility model is structurally by setting gradually modified poly ester enamelled coating from the inside to the outside on the surface at circular copper wire, polyester-imide enamelled coating, polyamidoimide enamelled coating and nylon enamelled coating, and to formation modified poly ester enamelled coating, polyester-imide enamelled coating, the individual layer number of plies of polyamidoimide enamelled coating and nylon enamelled coating limits, the thickness in monolayer forming these enamelled coatings is set as identical numerical value simultaneously, when thickness in monolayer is 0.0028-0.0032mm, enamelled wire structural behaviour is even, there is resistance to elevated temperatures good, long service life, adhesion property is good, the advantages such as puncture voltage is high and be heated evenly, being provided with nylon enamelled coating can make enamelled wire structure be applicable to high-speed winding, when the thickness limiting the individual layer forming each enamelled coating is 0.0031mm, the performance of enamelled wire structure is best, and resistance to elevated temperatures improves 25%, and aging speed reduces 20%, and useful life extends 18%, and puncture voltage (KV) is more than 12.00, and the thickness in monolayer of each enamelled coating is set to identical numerical value, thus make enamelled wire when producing, paint convenient, need not often go adjustment coating apparatus to change the thickness in monolayer of each enamelled coating, thus shorten the thickness in monolayer regulation time of each enamelled coating, improve the production efficiency of enamelled wire, for enterprise brings larger economic benefit.
