The construction of span route, the input cost of shaft tower when reducing line construction, saves valuable land resource, reduces electric power and is transmitting
In loss, improve power transmission efficiency purpose conducting wire be of great significance.
Utility model content
The purpose of this utility model is to provide a kind of heat-resistant aluminum alloy wires with Extra High Strength strengthening core, to solve
Conducting wire certainly in the prior art be not able to satisfy big section, large span route construction demand the problem of.
The utility model provides a kind of heat-resistant aluminum alloy wire with Extra High Strength strengthening core, including strengthening core, packet
Coating, the strengthening core are set to clad and are formed by cavity, and the strengthening core is twisted by several Extra-high-strength aluminium-clad steel wires
It closes, the clad is twisted by several heat resistant aluminum alloy wires.
Further, the intensity of the aluminum-clad steel wire is more than or equal to 1700Mpa.
Further, the aluminum-clad steel wire includes steel core and the metallic aluminium for being set to steel core surface.
Further, the intensity of the steel core is more than or equal to 1700MPa.
Further, described 2 layers of cladding layer arrangement.
Beneficial effect using above-mentioned technical solutions of the utility model is:
The utility model aluminium alloy conductor forms strengthening core, and strengthening core external sheath using Extra High Strength aluminium Baogang is twisted
Heat resistant aluminum alloy wire, the comprehensive breaking strength and transmission line capability of conducting wire are greatly improved, specific manifestation in the following areas:
The heat-resisting aluminium alloy twisted wire integral strength of Extra High Strength aluminium Baogang strengthening core greatly promotes, so as to increase bar away from
Or reduce arc sag；
The clad that heat resistant aluminum alloy wire is twisted meets the construction in big section, large span route, reduces electric power
Loss in the transmission, improves power transmission efficiency；
The continuous work for the clad that heat resistant aluminum alloy wire is twisted allows temperature to can achieve 210 DEG C, improves current-carrying
60% or more amount, generates apparent energy-saving benefit.
Detailed description of the invention
Fig. 1 is the utility model heat-resistant aluminum alloy wire structural schematic diagram；
In attached drawing, parts list represented by the reference numerals are as follows:
1- aluminum-clad steel wire, 2- aluminium alloy wire, 3- steel core, 4- metallic aluminium.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.
As shown in Figure 1, a kind of heat-resistant aluminum alloy wire with Extra High Strength strengthening core of the present embodiment, including strengthening core,
Clad, the strengthening core are set to clad and are formed by cavity, and the strengthening core is by several Extra-high-strength aluminium-clad steel wires 1
It is twisted, the clad is twisted by several heat resistant aluminum alloy wires 2.
In the embodiment, aluminum-clad steel wire base is produced using continuously extruded seamless welding technology, aluminum-clad steel wire base wire drawing uses
Hydrodynamic lubrication technology, increases a pressure inlet before wire drawing die, and adhesive tape of the wire drawing powder by moving steel wire is constantly sent
Entering in wire drawing die, this method changes the metal stresses state deformed in mold, higher radial stress is increased, so that
Aluminium being capable of deformation synchronous with steel.Predeformation and rear deformation process are carried out when twisted, eliminate most of monofilament residual stress and are twisted
Stress caused by process, so that twisted wire is more compliant.
Heat-resisting aluminium alloy is by slip wire drawing machine wire drawing, and the size of slippage decides that sliding generates function in drawing process
The size of rate loss, but has the presence centainly slided, be conducive in drawing process between wire rod tension automatic adjustment, reduce
The generation broken in high-speed wire-drawing.So the present embodiment aluminum alloy drawing equipment uses micro- sliding type, slide coefficient 1.0
~1.01, it had both reduced energy consumption and has also ensured wire drawing quality.
Specifically, the aluminum-clad steel wire 1 includes steel core 3 and the metallic aluminium 4 for being set to 3 surface of steel core, the aluminum-clad steel wire 1
It is all larger than with the intensity of steel core 3 equal to 1700Mpa.
Further, in the embodiment, described 2 layers of cladding layer arrangement.
To sum up, the utility model aluminium alloy conductor forms strengthening core using Extra High Strength aluminium Baogang is twisted, and outside strengthening core
Layer cladding heat resistant aluminum alloy wire, the comprehensive breaking strength and transmission line capability of conducting wire are greatly improved；
The heat-resisting aluminium alloy twisted wire integral strength of Extra High Strength aluminium Baogang strengthening core greatly promotes, so as to increase bar away from
Or reduce arc sag；
The clad that heat resistant aluminum alloy wire is twisted meets the construction in big section, large span route, reduces electric power
Loss in the transmission, improves power transmission efficiency；
The continuous work for the clad that heat resistant aluminum alloy wire is twisted allows temperature to can achieve 210 DEG C, improves current-carrying
60% or more amount, generates apparent energy-saving benefit.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
