Abstract
The utility model relates to a cable wire, in particular to a medium-strength aluminium alloy stranded wire. The medium-strength aluminium alloy stranded wire takes one or more medium-strength aluminium alloy wires as a reinforcing core and a plurality of layers of medium-strength aluminium alloy wires are wound around the reinforcing core in a spiral way; each layer of medium-strength aluminium alloy wires comprises a plurality of independent wires; the spiral winding directions of every two adjacent layers of aluminium alloy wires are opposite; and there can be three, four or five layers of the medium-strength aluminium alloy wires wound around the reinforcing core in a spiral way. By adopting the medium-strength aluminium alloy core, the tensile strength of the medium-strength aluminium alloy stranded wire is higher, the conductivity is higher, and the resistance to natural hazards is stronger.
Description
Technical field
The utility model relates to a kind of cable, relate in particular to a kind of middle strength aluminium alloy twisted wire.
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.
Summary of the invention
The purpose of this utility model is to provide a kind of middle strength aluminium alloy twisted wire at above-mentioned weak point, is a kind of middle intensity 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: middle strength aluminium alloy twisted wire by strength aluminium alloy line in one or more as strengthening core, be wound with strength aluminium alloy line in the multilayer at the peripheral spiral of strengthening core, the strength aluminium alloy line comprises many single lines in every layer, and the spiral winding direction of every adjacent two layers aluminium alloy wire is opposite.
The strength aluminium alloy line is three layers in the described multilayer that is spirally wound on the strengthening core periphery.
The described middle intensity multilayer aluminium alloy wire that is spirally wound on the strengthening core periphery is four layers.
The described middle intensity multilayer aluminium alloy wire that is spirally wound on the strengthening core periphery is five layers.
Strength aluminium alloy twisted wire in the utility model makes tensile strength higher owing to adopted middle 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 a perspective view of the present utility model;
Fig. 2 is a sectional structure schematic diagram of the present utility model;
Fig. 3 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing 1~3, middle strength aluminium alloy twisted wire of the present utility model comprises strength aluminium alloy line 2 in strengthening core of being made up of middle strength aluminium alloy line 1 and the multilayer that is spirally wound on strengthening core core periphery.
Strengthening core 1 can be made of (the whole less situation of strength aluminium alloy twisted wire in being applicable to) a middle strength aluminium alloy line, can comprise that also the strength aluminium alloy line is spirally wound on the coating layer (the bigger situation of strength aluminium alloy twisted wire integral body in being applicable to) that this inner core periphery constitutes among the strengthening core 1 that is made of many middle strength aluminium alloy lines and the Duo Gen.
Be spirally wound on that strength aluminium alloy line 2 respectively comprises many single lines of the same size in the multilayer of strengthening core 1 periphery, the spiral winding direction of strength aluminium alloy line is opposite in every adjacent two layers.Be spirally wound on that the strength aluminium alloy line can be three layers, four layers or five layers as required in the multilayer of strengthening core periphery.
