Problems solved by technology

[0002] With the wide application of high-power power supply filters and high-frequency high-voltage transformers, the demand for high-voltage, high-temperature-resistant, and large-section high-frequency enamelled winding wires has increased. The maximum cross-sectional area of ​​strands produced by the machine (equipment) can only reach 1.5mm 2 , while the 1.5mm 2 The above industrial needs can only be assembled by the secondary manual processing of the manufacturer, and it is also necessary to cover the outer surface with polyester film or polyimide film to shape, that is, the consistency of the product diameter cannot be guaranteed, and it is impossible to bring the product Quality assurance, but also a lot of waste of human and material resources

Abstract

The invention provides an anti-impulse tensile high frequency enamelled winding wire characterized by comprising metal wire cores and a polyester protection layer; a number of the metal wire cores are intertwisted into a bundle on an outer side of which the polyester protection layer is coated; or a number of the metal wire cores are intertwisted into a group which forms an enamelled wire primary group, a number of enamelled wire primary groups are intertwisted into a bundle on an outer side of which the polyester protection layer is coated; a polyamide-imide coating layer is coated on an outer side of the polyester protection layer. Compared with technologies of the prior art, the anti-impulse tensile high frequency enamelled winding wire is markedly advantageous in that when the anti-impulse tensile high frequency enamelled winding wire is applied to a large power and high frequency filtering inductor or a high frequency and high voltage transformer, high frequency performance can be realized, power consumption can be lowered, and energy can be saved by more than 20%; the anti-impulse tensile high frequency enamelled winding wire is high in flexibility, ductility and pull resistance.
