Problems solved by technology
Generally, the winding wires matched with reactors, transformers and motors use copper as the conductor, which has good electrical conductivity but the cost is too high, and the insulation layer attached to the surface of the copper material has poor continuity, poor conductor forming tightness, and poor insulation performance. There are many problems such as the difficulty in handling the interface between the layer and the conductor, which affects many performances of the product

Embodiment Construction
[0013] Production steps:
[0014] 1. Cleaning of bare aluminum rods: soak the aluminum rods in a pool of sodium hydroxide aqueous solution with a molar concentration of 5%, and pass them at a speed of 5-10 meters per minute to clean off surface impurities and oil stains; The aluminum rods cleaned by the aqueous solution are cleaned with tap water to remove the retained sodium hydroxide solution, and then dried by a blow-drying device for later use.
[0015] 2. Aluminum rods are formed into aluminum wires by extrusion: the traditional wire drawing process is replaced by an extrusion process, which improves the surface finish and the density of the aluminum material, thereby increasing the current intensity; the crystal structure of the material changes from a long strip to a long structure , thereby improving the mechanical strength of the product.
[0016] 3. After coating the heat-resistant polyester primer on the aluminum wire, then coat the polyamide-imide topcoat to form ...

Abstract
The invention discloses a production method of a transposed winding conducting wire for an environment-friendly reactor, which relates to the technical field of electrical appliances. The production method comprises the following steps: firstly cleaning bare aluminum rods, further forming aluminum wires by extruding the aluminum rods, then coating heat-resistant polyester primers outside the aluminum wires, further coating polyamide-imide finish coats, forming lacquered wires, finally twisting at least five lacquered wires, and winding polyamide-imide outside the twisted lacquered wires. The production method can solve the difficult problems of poor forming compactness of a conductor, difficult treatment of an interface between an insulating layer and the conductor, non-ideal insulation effect and the like in the prior art, and has low cost, high performances and environmental protection, and the product can be widely applied in the industrial and civil fields of track traffic, nuclear power plants, power plants and the like.
Description
technical field [0001] The invention relates to the technical field of electric appliances. Background technique [0002] Winding wires are divided into reactors, motors and winding wires for transformers by product type. Generally, the winding wires matched with reactors, transformers and motors use copper as conductors, which have good electrical conductivity but high cost, and the insulation layer attached to the surface of copper has poor continuity, poor conductor forming tightness, and poor insulation performance. There are many problems such as the difficulty in handling the interface between the layer and the conductor, which affects many properties of the product. Contents of the invention [0003] The purpose of the invention is to design a production method for transposition winding wires for environmental protection reactors with good insulation and stable conduction. [0004] The present invention comprises the following steps: [0005] 1) Cleaning of bare ...
