Seamless lapped wire and preparation method thereof

Abstract

The invention relates to a seamless lapped wire and a preparation method thereof, and belongs to the technical field of cable preparation, and adopts the technical scheme that the seamless lapped wire comprises a conductor wire core and an insulating layer arranged on the outer side of the conductor wire core, and the outer side of the insulating layer is wrapped with a lapped wire layer; a locking ring is arranged along the length direction of the conductor wire core and between the insulating layer and the lapped wire layer; the lapped wire layer comprises an anti-cracking layer and a compact layer, wherein the anti-cracking layer is wound on the outer sides of the locking rings, between the adjacent locking rings and located on the outer side of the insulating layer, and the compact layer is wound on the outer side of the anti-cracking layer. Through the scheme, the anti-pressure capability of the lapped wire can be improved, the lapped wire is prevented from being broken, and the service life of the lapped wire is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cable preparation, and in particular relates to a seamless wrapping wire and a preparation method thereof. Background technique [0002] As we all know, as one of the main forms of electrical insulation, wire and cable insulation is actually the pursuit of a comprehensive balance of electrical properties, thermal properties and mechanical properties, including wear resistance, cutting resistance, chemical resistance, flame retardancy, and smoke generation. The comprehensive balance of properties such as weight, operating temperature grade, and dielectric properties. [0003] When processing insulated wrapping wires, a perfect ratio must be achieved between the wire diameter of the edge wrapping wire, the width and thickness of the wrapping film, the overlap rate, the wrapping pitch, and the wrapping angle. At the same time, it must be considered in the structural design Film stretching. [0004] In some...

AI Technical Summary

Problems solved by technology

[0004] In some special working conditions, the outer side of the wrapped wire will bear relatively large pressure during use. Under the effect of relatively high pressure on the wrapped wire, the wrapped wire will be deformed to varying degrees under greater pressure. The outer insulation layer is easy to crack, and the inner wire is easy to deform and break, which will affect the service life of the wrapped wire
