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

Abstract

The invention discloses a forming process of electric wire fixing preformed armor rods. The forming process comprises the steps of forming-head polishing-cleaning-rod selection-twisting-binding-gum dipping-ribbon shearing (ribbons for binding)-marking-sand spreading-combining-bending. The forming process overcomes the defects of the prior art, and is reasonable in layout; steel wire strips of each set of steel wires are connected tightly; each steel wire in each set of the steel wires is specially treated, so that the preservative effect is good; and the preformed armor rods are high in twisting strength, so that the loose phenomenon is not generated in use.

Description

Technical field [0001] The invention relates to the technical field of power transmission lines, and in particular belongs to a pre-twisted wire forming process for wire fixing. Background technique [0002] After searching the relevant patent documents, the pre-twisted yarn and its preparation method that are the same as the present invention have not yet been retrieved. The existing electric power industry uses pre-twisted wires to fix the anti-vibration hammers or spacers on the transmission and distribution lines. Because the pre-twisted wires are convenient to use, they are more and more popular. The pre-twisted wire currently used is generally aluminum wire pre-twisted wire or aluminum-clad steel pre-twisted wire; due to its insufficient strength, the fixed point of the aluminum wire is prone to loosening after being used for a period of time; the existing aluminum The clad steel pre-twisted wire adopts the method of covering the steel wire with an aluminum layer to make t...
