Abstract
The utility model particularly relates to a light in weight, the extra -high voltage smart power grids's stand wear and tear aluminium alloy wire who has good wearability. Aluminium alloy wire include the aluminum alloy sinle silk that stranded high strength aluminum alloy line hank system formed, the outside parcel mica tape layer of sinle silk, mica tape layer's the outside sets up the crosslinked polyethylene layer, the outside on crosslinked polyethylene layer sets up the kai fula fibrous layer, the outside of kaifula fibrous layer sets up the PPEK insulating layer. The sinle silk outside sets up 3 layers of insulating layer altogether, and insulating effectual, mica tape layer still has good fireproof effect except that the insulation, use the kai fula fibrous layer as the protective layer, improved the wearability of wire, and kaifula fibrous layer light in weight, wire whole weight reduced.
Description
Technical field
This utility model is related to electric wire grid equipment field, and the wear-resistant aluminum of more particularly to a kind of extra-high voltage intelligent grid is closed
Golden wire.
Background technology
With the increase of power consumption, it is desirable to which the current-carrying capacity of cable is increasing, the cable core cross-section of cable constantly increasing,
The long measure and length of cable also increases in the benefit of mouth therewith.Existing cable, generally complete copper or full aluminum, due to copper
The non-oxidizability of matter cable, welding performance and electric conductivity are superior to aluminum, are widely used in the big field of electric current；But copper electricity
Cable is higher due to expensive and density, is replaced by aluminum conductor under some use conditions.At present in world many countries
Aluminium alloy conductor is widely used on transmission line of electricity, and they are mainly high-strength aluminum alloy line.China's wire in 1999 is listed in
National standard has 3 kinds of forms：
Aluminium alloy stranded conductor (hereinafter referred to as AAAC), the aluminium alloy wire that whole line segments have homogeneity is constituted；Aluminium alloy core, aluminium
Twisted wire (hereinafter referred to as ACAR), its core be aluminium alloy wire, outer layer process electrician circle aluminum steel；Steel core aluminum alloy stranded wire (letter below
Claim AACSR), its core be high intensity steel wire, outer layer process aluminium alloy wire.
China started to develop and develop high-strength aluminum alloy line from the sixties in 20th century.The popularization and application on 500kV circuits
AAAC, makees wire using AAAC on extra high voltage network, compared with the steel-cored aluminium strand (ACSR) for generally adopting at present,
Have the following advantages：Sag characteristic is good, corrosion-resistant, surface resistant to damage, and percentage elongation is big, and energy loss is few, and hot properties is good.
But the insulating barrier and protective layer of current AAAC twisted wires still continue to use the insulating barrier and protective layer of ACAR, its protective layer
It is easy to transported equipment during transport and laying to cut or scratch, when such as using crane transfer or installing, lifting
Machine suspension hook some spines may cause the protective layer of twisted wire to be destroyed, and so as to leave trouble to safety, cause the generation of peril,
And the protective layer on the outside of traditional twisted wire is heavier, causes twisted wire total quality larger.The insulating barrier of general AC AR only has one layer, once
Insulating barrier local damage, can cause whole insulating barrier all to fail.
The content of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of lightweight, good insulation preformance, with good wear-resisting
The abrasion-resistance aluminum alloy wire of the extra-high voltage intelligent grid of property.
For achieving the above object, the technical scheme adopted by this utility model is：A kind of extra-high voltage intelligent grid it is wear-resisting
Aluminium alloy conductor is damaged, described aluminium alloy conductor includes the aluminium alloy core of multiply high-strength aluminum alloy line process；It is described
The outside parcel Muscovitum belt of core, the outside of Muscovitum belt arrange cross-linked polyethylene layer, and the outside of cross-linked polyethylene layer is arranged
Kafra fiber layer, the outside of Kafra fiber layer arrange PPEK insulating barriers.
Preferably, the number of share of stock of described aluminium alloy core is 45 strands or 61 strands.
Preferably, described Muscovitum belt is two-sided synthetic mica belt or one side synthetic mica belt；Described Kev
Draw；Described PPEK insulating barriers are macromolecular material
The insulating barrier of heterocycle biphenyl polyether ketone.
This utility model has the advantages that：Muscovitum belt, cross-linked polyethylene layer, PPEK insulation are set on the outside of core
Layer totally 3 layer insulating, insulation effect are good, after the insulating barrier in outside loses insulation effect, the insulating barrier still effective protection of inner side
Core；Muscovitum belt also has good flameproof effect；Using Kafra fiber layer as protective layer, the wear-resisting of wire is improve
Property, and Kafra fiber layer weight is light, reduces wire overall weight.
Description of the drawings
Fig. 1 is aluminium alloy conductor schematic cross-section.
Specific embodiment
A kind of abrasion-resistance aluminum alloy wire of extra-high voltage intelligent grid as shown in Figure 1, including multiply high-strength aluminum alloy
The aluminium alloy core 1 of line process, 1 preferred number of share of stock of aluminium alloy core are 45 strands or 61 strands.The outside parcel of the core 1
Muscovitum belt 2, Muscovitum belt 2 function as insulated waterproof layer, and its structure can be two-sided synthetic mica belt, it is also possible to
It is one side synthetic mica belt；Two-sided synthetic mica belt is, with synthetic mica paper as base material, to make two-sided benefit with glass fabric
Strong material, i.e., formed the glass fabric bonding of mica paper and its both sides with silicon resin adhesive；One side synthetic mica belt
It is, with synthetic mica paper as base material, to make single-side reinforced material with glass-fiber-fabric, i.e., with silicon resin adhesive by mica paper and its side
Glass fabric bonding form.During using one side synthetic mica belt, the glass fabric of its side is contacted with core 1, is prevented
Only core 1 pokes mica paper, plays the protective effect to mica paper.
The outside of Muscovitum belt 2 arranges cross-linked polyethylene layer 3, and the second layer that functions as of cross-linked polyethylene layer 3 insulate
Layer, its thickness should be greater than the thickness of Muscovitum belt 2.The outside of described cross-linked polyethylene layer 3 arranges Kafra fiber layer 4, triumphant
Husband draw fibrous layer 4 effect be protect its on the inside of arrange core 1, Muscovitum belt 2, cross-linked polyethylene layer 3, Kafra fiber tool
There are high intensity, high abrasion, high tear resistance, improve protected effect, especially more sharp sharp sword, burr etc. are had well
Protection effect, and high abrasion resistance.
The outside of described Kafra fiber layer 4 arranges PPEK insulating barriers 5, and PPEK insulating barriers 5 are miscellaneous for macromolecular material
The insulating barrier of ring biphenyl polyether ketone, which functions as outer insulation.In order to improve the intensity of PPEK insulating barriers 5, preferably
Embodiment is：Carried out using epoxy resin layer 6 between described Kafra fiber layer 4 and PPEK insulating barriers 5 bonding.
