Abstract
The utility model provides a medium-strength aluminum alloy stranded wire. One or a plurality of medium-strength aluminum alloy stranded wires are used as a reinforcing core. A plurality of medium-strength aluminum alloy stranded wires are spirally wound on the exterior of the reinforcing core. Each medium-strength aluminum alloy stranded wire respectively comprises a plurality of medium-strength aluminum alloy single wires. The spiral winding directions of every two adjacent medium-strength aluminum alloy stranded wires are opposite. As the medium-strength aluminum alloy core is used, the medium-strength aluminum alloy stranded wire has high tension strength, high conductivity, and strong capability of resisting natural disasters.
Description
Technical field
The utility model relates to a kind of cable, relates 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.
The utility model content
The purpose of this utility model is exactly in order to provide a kind of middle strength aluminium alloy twisted wire with good tensile strength and good electrical conductivity.
In order to achieve the above object, the utility model has adopted following technical scheme: 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 middle strength aluminium alloy single lines in every layer, and the spiral winding direction of strength aluminium alloy line is opposite in every adjacent two layers.
The strength aluminium alloy line is three layers in the described multilayer that is spirally wound on the strengthening core periphery.
The strength aluminium alloy line is four layers in the described multilayer that is spirally wound on the strengthening core periphery.
The strength aluminium alloy line is five layers in the described multilayer that is spirally wound on the strengthening core periphery.
The strength aluminium alloy twisted wire has been owing to adopted middle strength aluminium alloy core in the utility model, thereby tensile strength is higher, and conductance is higher, and the ability of opposing natural calamity is stronger.
Description of drawings
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 plan structure schematic diagram of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, strength aluminium alloy twisted wire in of the present utility model, by strength aluminium alloy line in one or more as strengthening core 1, be wound with strength aluminium alloy line 2 in the multilayer at strengthening core 1 peripheral spiral, the strength aluminium alloy line comprises many middle strength aluminium alloy single lines in every layer, and the spiral winding direction of strength aluminium alloy line is opposite in every adjacent two layers.
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 inner core that is made of a middle strength aluminium alloy line and the Duo Gen.
Be spirally wound in the multilayer of strengthening core periphery strength aluminium alloy line 2 respectively comprise many of the same size in the strength aluminium alloy single lines, the spiral winding direction of strength aluminium alloy line is opposite in every adjacent two layers, is 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.
