The invention provides a combination wire with good electromagnetic property. The combination wire comprises a support line, two layers of conductors, a layer of protection sleeve and self-adhesive filaments, wherein a first insulating layer covers the outside of the support line; the two layers of conductors cover the outer side of the support line and a second insulating layer covers the outer sides of the conductors; the protection sleeve covers the outer sides of the conductors; gaps between the conductors are filled with the self-adhesive filaments; and the conductors are spirally wound on the support line. The combination wire with good electromagnetic property is simple in structure and convenient to manufacture; multiple strands of conductors are spirally wound on the support lineand the current directions of the support line and the conductors are opposite, so that most of electromagnetic waves can be eliminated and the influences of the electromagnetic waves on equipment arereduced; the gaps between the conductors are filled with the self-adhesive filaments, so that the adhesion of the combination wire can be provided and the service life of the combination wire is prolonged.
Description
technical field [0001] The invention relates to a combined wire with good electromagnetic performance, in particular to a combined wire with good electromagnetic performance. Background technique [0002] Magnet wires are mainly used in the windings of transformers, motors and various electrical equipment. The magnet wires in the prior art are covered with insulating layers on the conductors, which usually have the following disadvantages: (1) The insulation structure is unreasonable, and the closure of the magnet wires Poor resistance, easy hydrolysis, and poor water resistance; (2) Imported materials are used, and the manufacturing cost is high, which is not suitable for general use. Therefore, there is an urgent need for a magnetic wire with good insulation and water resistance, low cost and universal application. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a combined wire with good electromagnetic properties....
