Problems solved by technology

Transformers using transposed wires can significantly reduce the volume and reduce losses. However, the structure needs to be bent many times when it is wound into a coil. Therefore, the insulating paper on the outer layer is easy to wear, which affects the performance of the transposed wires. safety

Embodiment Construction

[0012] As shown in the figure, in order to solve the above-mentioned technical problems, a transposition wire of the present invention includes a wire body 1 and a polyimide layer 2 coated on the wire body 1. Since the wire body 1 is covered with a polyimide layer 2 , can improve the insulation and safety of the transposition wire, and only the polyimide layer is coated on the outer body of the wire, so the structure is simple and the manufacturing cost is low.

[0013] In order to further improve the insulation of the transposed wire, when the polyimide layer 2 is processed as a polyimide film, the polyimide is coated on the outside of the wire body 1 and dried to form a film layer.

[0014] To sum up, compared with the prior art, the present invention has the advantages of strong insulation performance, good safety, simple structure and low cost.

[0015] The description and application of the present invention here are illustrative, and are not intended to limit the scope o...

Abstract

The invention provides a transposed conductor which comprises a conductor body and a polyimide layer covering the conductor body. Due to the polyimide layer covering the conductor body, insulativity and safety of the transposed conductor can be improved. Besides, since only an insulating layer is coated outside insulating layer, the transposed conductor is simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to a wire, in particular to a transposed wire. Background technique [0002] Transposed wire is a new material widely used in the field of transformer production in recent years. As the capacity of the transformer increases, the cross-sectional area of ​​the winding wire will also increase in a certain proportion. However, due to the limitations of many factors such as electrical loss index, wire production process conditions and user use conditions, it is impossible to produce wires with extra large cross-sections. As a result, a new winding wire-transposition wire is produced. [0003] The transposition conductor of present technology is to exchange arranging positions successively on special transposition conductor equipment with many single high-quality enamelled copper flat wires or paper-coated flat wires and carry out transposition. Finally, the outer layers of the transposed enameled wires are covered with insulating pa...
