Abstract
Provided is an aluminum alloy twisted wire with high conductivity and high strength. One or more aluminum alloy wires with high conductivity and high strength are used as a reinforcing core. Multiple layers of aluminum alloy wires with high conductivity and high strength are wound spirally on the outer side of the reinforcing core. Each layer of aluminum alloy wires with high conductivity and high strength comprises multiple single wires. Every two adjacent aluminum alloy wire layers have opposite spiral winding direction. By using the aluminum alloy core with high conductivity and high strength, the aluminum alloy twisted wire with high conductivity and high strength achieves high tensile strength, high conductivity, and a strong capability of resisting natural disasters.
Description
Technical field
The utility model relates to a kind of aerial condutor, relate in particular to a kind of high conductivity high strength 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 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.
Summary of the invention
The purpose of this utility model is to provide a kind of high conductivity high strength aluminium alloy stranded conductor at above-mentioned weak point, is a kind of high conductivity high strength cable with good tensile strength and good electrical conductivity.
In order to achieve the above object, the utility model has adopted following technical scheme to realize:
The high conductivity high strength aluminium alloy stranded conductor by one or more high conductivity high strength aluminium alloy wire as strengthening core, be wound with the high conductivity high strength aluminium alloy wire that is no less than one deck at the peripheral spiral of strengthening core, each is made up of every floor height conductance high-strength aluminum alloy line many single lines, and the spiral winding direction of every adjacent two layers aluminium alloy wire is opposite.
The described multilayer high conductivity high strength aluminium alloy wire that is spirally wound on the strengthening core periphery is three layers.
The described multilayer high conductivity high strength aluminium alloy wire that is spirally wound on the strengthening core periphery is four layers.
The described multilayer high conductivity high strength aluminium alloy wire that is spirally wound on the strengthening core periphery is five layers.
The beneficial effects of the utility model are, the high conductivity high strength aluminium alloy stranded conductor makes tensile strength higher owing to adopted the high conductivity high strength aluminium alloy core, and conductance is higher, and the ability of opposing natural calamity is stronger.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing:
Fig. 1 is perspective view of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model;
Fig. 3 is plan structure schematic diagram of the present utility model.
