Aluminum clad steel pre-stranded wire and preparation method thereof

Abstract

The invention relates to an aluminum clad steel pre-stranded wire for fixing a damper or a spacing bar in power transmission and distribution circuits of the power industry and a preparation method thereof. The aluminum clad steel pre-stranded wire consists of an inner core steel wire, an aluminum clad layer and end face treatment layers, wherein the aluminum clad layer is clad on the periphery of the inner core steel wire, and the end face treatment layers are clad at two ends of the inner core steel wire and the aluminum clad layer or the end of the inner core steel wire. Because the end face of the pre-stranded wire is designed into a duckbilled shape, the pre-stranded wire is bound with a power transmission cable more firmly; because the end faces are provided with the treatment layers, the rust corrosion of the end faces is avoided; because the oxide layer on the end face of the inner core steel wire is cleared by adopting the methods of quick burnishing, polishing and the like, corrosion of acid washing on the aluminum clad layer is avoided, and pollution of acid to the environment is reduced; and a flexible blanket is placed in a container, and a plating aid is coated on the inclined plane of the inner core steel wire by adopting a rubbing method, so corrosion of the aluminum clad layer is reduced.

Description

technical field [0001] The invention relates to a pre-twisted wire for fixing an anti-vibration hammer and its accessories for power transmission and distribution lines in the electric power industry, in particular to an aluminum-clad steel pre-twisted wire for fixing an anti-vibration hammer and spacers and a preparation method thereof. Background technique [0002] After retrieving the relevant patent documents, the same aluminum-clad steel pre-twisted wire and its preparation method as that of the present invention have not yet been retrieved. The existing power industry adopts pre-twisted wires to fix the anti-vibration hammers or spacers on the transmission and distribution lines. Because the pre-twisted wires are easy to use, they are more and more popular. The existing pre-twisted wires are generally aluminum wire pre-twisted wires or aluminum-clad steel pre-twisted wires; due to the insufficient strength of aluminum wire pre-twisted wires, the fixed points are prone ...

AI Technical Summary

Problems solved by technology

However, due to the phenomenon of exposed steel wires in the broken section of the pre-twisted wires, corrosion and other phenomena on the surface of the steel wires appear after a period of outdoor use, which brings certain hidden dangers to the project. Therefore, it is necessary to improve the existing pre-twisted wires. Improve power transmission and distribution capabilities
