Multi-strand flat enameled wire and manufacturing method thereof

Abstract

The invention discloses a multi-strand flat enameled wire and a manufacturing method thereof, under the condition that the specified size of a conductor is not changed, a plurality of flat conductors are doubled to form the conductor with the specified size, equivalently, the conductor with the specified size is divided into a plurality of overlapped flat wire conductors, and the original perimeter of the conductor is changed into the sum of the perimeters of the plurality of flat wire conductors; under the condition that the length of the conductor is not changed, the perimeter of the conductor is increased, so that the surface area of the conductor is increased, and the problem of skin effect of the conductor is effectively solved; after the flat conductors are doubled, movement co-construction between wires is increased, and the problem of poor flexibility of the wires can be well solved; and the finished multi-strand flat enameled wire is suitable for the fields of new energy automobiles and the like, and not only meets standard requirements, but also meets customer requirements.

Description

technical field [0001] The invention relates to the technical field of enameled wire, in particular to a multi-strand flat enameled wire and a manufacturing method thereof. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, and thermal properties; enameled wire is the main raw material for charging piles, new energy vehicles, motors, electrical appliances and household appliances, especially the new energy vehicle industry has ach...

Problems solved by technology

[0003] Ordinary enameled wires have the problem of difficult winding in practical applications. Because enameled wires generally have relatively large specifications, the flexibility of the wires is poor, and the application efficiency is low (small surface area and cross-sectional area); customers have always hoped to provide a flexible It is a new type of multi-strand flat enameled wire that solves the problem of skin effect, so that when they wind the coil, it can well solve the problem of difficult winding due to poor flexibility of the wire, and it is not easy to damage the paint film. Multiple parallel flat wires are used After the enameled wire and the coil are wound, the section ratio and surface area can be greatly increased. The products are mainly used in the motors of new energy vehicles. In the prior art, flat enameled wires have not been produced, which cannot meet the needs of customers. It is necessary to provide a Innovative manufacturing process to produce multi-strand flat enameled wire
