Abstract
The present invention relates to a carbon fiber complex core high elongation duralumin stranded wire. The carbon fiber complex core high elongation duralumin stranded wire comprises a carbon fiber complex core wire which is coated with an insulation layer, and the multiple layers of duralumin stranded wires from inside to outside are arranged at the exterior of the insulation layer, wherein the insulation layer concretely employs organosilane crosslinked polyethylene; the multiple layers of duralumin stranded wires from inside to outside concretely employ three layers of duralumin stranded wire structures from inside to outside; and the diameter of the carbon fiber complex core wire is 2-2.5 times of the diameter of each duralumin stranded wire, the stretching rate of the carbon fiber complex core wire is not less than 2.5%, and the operation temperature of the carbon fiber complex core wire is not less than 120 DEG C. The carbon fiber complex core high elongation duralumin stranded wire is light per weight and large in pulling strength so as to improve the stretching and weight ratio of the wire; and moreover, compared to the steel core aluminum stranded wire with the same outer diameter, the weight is reduced by 17.7%, the stretching is improved about 20%, the sag feature is good, and the long-item operation temperature is improved to 120 DEG C, so that the current-carrying capability can be doubled, the deficiency of construction and wire putting of soft aluminum stranded wire can be improved, and the carbon fiber complex core high elongation duralumin stranded wire can perform long-distance stringing and is especially suitable for new construction of lines.
Description
Technical field
The invention belongs to power cable technical field, particularly a kind of carbon fiber complex core height stretches rate duralumin twisted wire.
Background technology
Power cable conductor domestic at present all adopts copper conductor substantially, and China or a copper resource most deficient
Country, but bauxite resource is extremely abundant, has begun to the conductor as cable with aluminium alloy early in 40 Duo Nianqian American-European countries,
Copper conductor is replaced to have become as a kind of inexorable trend with aluminium alloy conductor, steel core cable also obtains in remote distance power transmission simultaneously
Arrive application, but either copper conductor cable or steel core cable, due to the heavier-weight of its own, have therefore given distance stringing
Bring heavy gravity load.
Content of the invention
The purpose of the present invention is for the deficiencies in the prior art, and proposes a kind of carbon fiber complex core height and stretch rate duralumin strand
Line.
The present invention solves its technical problem and takes technical scheme below to realize：
A kind of carbon fiber complex core height stretches rate duralumin twisted wire, including carbon fiber complex core line, in carbon fiber complex core line
Outer wrap has insulating barrier, is furnished with multilamellar duralumin twisted wire from inside to outside in insulating barrier outer row.
And, described insulating barrier specifically adopts organosilane crosslinked polyethylene.
And, the concrete three layers of duralumin twisted wire structure adopting from inside to outside of described multilamellar duralumin twisted wire from inside to outside.
And, the diameter of described carbon fiber complex core line is 2-2.5 times of every duralumin twisted wire diameter, carbon fiber complex core
The expansion and contraction 2.5% of line, 120 DEG C of running temperature.
Advantages of the present invention and good effect are：
1st, the present invention and steel-cored aluminium strand ratio, during same outer diameter, has that lightweight, pull-off force is big, linear expansion coefficient is little.
2nd, the cable light unit weight of the present invention, pull-off force are big, then wire draws anharmonic ratio to improve, and twists with same outer diameter steel-core-aluminium
Line weight/power ratio have dropped 17.7%, and pulling force improves 20%.
3rd, because cable linear expansion coefficient of the present invention is little, sag characteristic is good, can improve longtime running temperature to 120 DEG C, thus
Current capacity can be double.
4th, stretch the duralumin round wires of rate due to present invention employs height, be easy to lay stringing, similar to traditional twisted wire, improve
The deficiency of soft aluminum stranded conductor the construction line-putting, thus newly-built circuit can be particularly well-suited to distance stringing.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is implemented to be further described, following examples are descriptive, be not to limit
Property it is impossible to protection scope of the present invention is limited with this.
A kind of carbon fiber complex core height stretches rate duralumin twisted wire, as shown in figure 1, including carbon fiber complex core line 1, in carbon fiber
The outer wrap of compounded yarn has insulating barrier 2, is furnished with multilamellar duralumin twisted wire 3 from inside to outside in insulating barrier outer row.
In being embodied as of the present invention, described insulating barrier specifically adopts organosilane crosslinked polyethylene.
In being embodied as of the present invention, described multilamellar duralumin twisted wire from inside to outside concrete using 3 layers from inside to outside
Duralumin twisted wire structure.
In being embodied as of the present invention, the diameter of described carbon fiber complex core line is the 2- of every duralumin twisted wire diameter
2.5 times, the expansion and contraction 2.5% of carbon fiber complex core line, 120 DEG C of running temperature.
Carbon fiber complex core height stretches rate duralumin twisted wire that lightweight, tensile strength is high, heat stability is good, current-carrying capacity is big and resistance to
The advantages of corrosion.In addition carbon fiber complex core height is stretched rate duralumin twisted wire line and is overcome composite core soft aluminum molded line with twisted wire the construction line-putting and is stranded
Difficult defect.Therefore, carbon fiber complex core height is stretched rate duralumin twisted wire and be can be widely applied to newly-built circuit and transform in circuit, has
Higher safety and economy.Carbon fiber complex core height stretches the performance comparison such as following table of rate duralumin twisted wire and conventional wire cable：
