Abstract

The utility provides a steel core aluminum alloy stranded wire, which comprises a steel core, and multi-layer aluminum alloy wires, wherein the steel core is composed of steel wires, the multi-layer aluminum alloy wires are spirally wound around the outer circumference of the steel core, each layer aluminum alloy wires includes multiple single wires, and the spirally winding directions of each two adjacent layers aluminum alloy wires are opposite. The utility model utilizes a steel core structure, thereby resistance to the tensile strength is higher, and the capability of resisting natural disasters is stronger.

Description

The steel core aluminium alloy stranded conductor

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of steel core aluminium alloy stranded conductor.

Background technology

Cable is widely used in transmission line, especially aerial high-voltage power transmission line.For being used for the cable of aerial high-voltage power transmission line, not only require it to have excellent conducting performance, also require it to have very high tensile strength.Cable now commonly used is an aluminium alloy stranded conductor, but simple aluminium alloy stranded conductor tensile strength is not enough, is subjected to the influence of natural calamity easily and breaks.

The utility model content

The purpose of this utility model is exactly in order to provide a kind of steel core aluminium alloy stranded conductor with good tensile strength.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of steel core aluminium alloy stranded conductor, comprise steel core of forming by steel wire and the multilayer aluminium alloy wire that is spirally wound on the steel core periphery, every layer of aluminium alloy wire comprises many single lines, and the spiral winding direction of every adjacent two layers aluminium alloy wire is opposite.

Described steel core comprises that the inner core and the Duo Gen steel wire that are made of a steel wire are spirally wound on the coating layer that this inner core periphery constitutes.

The described multilayer aluminium alloy wire that is spirally wound on the steel core periphery is three layers.

The described multilayer aluminium alloy wire that is spirally wound on the steel core periphery is four layers.

The described multilayer aluminium alloy wire that is spirally wound on the steel core periphery is five layers.

The utility model steel core aluminium alloy stranded conductor is owing to adopted structure of steel pole, thereby tensile strength is higher, and the ability of opposing natural calamity is stronger.
