Problems solved by technology

[0002] The paper of the existing aluminum paper-wrapped wire is wound in the same direction, which will easily cause the breakdown of the insulation layer, resulting in increased power consumption of the transformer, which cannot meet the needs of use. Therefore, a paper-wrapped wire whose insulation layer is not easy to be broken down is needed. Meet the needs of transformers and other equipment

Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0009] The aluminum paper covered wire includes an aluminum core 4, a first paper covering 1, a second paper covering 2 and a third paper covering 3, the first paper covering 1 is wrapped around the aluminum core, and the second paper covering is wrapped around the aluminum core. Wrapped on the outside of the first paper wrapping layer, and wrapped on the outside of the second paper wrapping layer by the third paper wrapping layer. The winding direction of the first paper wrapping layer is the same as that of the third paper wrapping layer and opposite to that of the second paper wrapping layer. That is, when wrapping, the first and third paper wrappings are wrapped clockwise, and the second paper wrapping is wrapped counterclockwise; or the first and third paper wrappings are wrapped counterclockwise, and the second paper wrapping is clockwise...

Abstract

The invention relates to the field of guide lines, in particular to an aluminum paper covered wire. The aluminum paper covered wire comprises an aluminum core, a first paper covered layer, a second paper covered layer and a third paper covered layer, wherein the first paper covered layer is lapped outside the aluminum core, the second paper covered layer is lapped outside the first paper covered layer, and the third paper covered layer is lapped outside the second paper covered layer. According to the aluminum paper covered wire provided by the invention, the winding gap is narrowed, so that raw materials are saved by 3%-4%, the cost is lowered, and meanwhile, the insulation safety of the aluminum paper covered wire is improved, so that the insulation of a wound transformer is improved greatly.

Description

technical field [0001] The invention relates to the field of wires, in particular to an aluminum paper covered wire. Background technique [0002] The paper of the existing aluminum paper-wrapped wire is wound in the same direction, which will easily cause the breakdown of the insulation layer, resulting in increased power consumption of the transformer, which cannot meet the needs of use. Therefore, a paper-wrapped wire whose insulation layer is not easy to be broken down is needed. Meet the needs of transformers and other equipment. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and to provide an aluminum paper-covered wire whose insulating layer is not easy to be broken down, which is specifically realized by the following technical solutions. [0004] An aluminum paper-wrapped wire, the aluminum paper-wrapped wire includes an aluminum core, a first paper wrap, a second paper wrap and a third paper wrap, the firs...
