Gold thread silk 122, the first aluminium alloy filament 121 is mutual stranded with the second aluminium alloy filament 122, the second aluminium alloy filament 122 it is straight
Footpath is less than the diameter of the first aluminium alloy filament 121.
Wherein, protective layer 200 is located at outermost layer, and lead body 100 is played a protective role.Protective layer 200 includes insulation
Layer 210 and screen layer 220, screen layer 220 are used for electric field and the magnetic field produced after shielded conductor body 100 is powered, it is to avoid externally
Boundary's equipment is interfered.Insulating barrier 210 is coated on outside screen layer 220, and it is isolation lead body 100 that it, which is acted on, bears corresponding
Voltage, prevents current leakage, prevents that lead body 100 from being destroyed.Insulating barrier 210 is crosslinked polyethylene material, this material
With good insulating properties and excellent heat resistance, it will not decompose and be carbonized below 300 degree, Long-term service temperature is reachable
90 degree, the thermal life was up to 40 years.
In the prior art, lead body is typically made up of steel core and aluminum stranded conductor, i.e., wrap up one layer of phase in steel wire outer surface
The aluminum steel being mutually hinged, steel wire is ferromagnetic material, primarily serves load effect, does not convey electric current substantially in alternating current circuit, on the contrary
Magnetic hystersis loss and eddy-current loss can be caused.
And in the present embodiment, lead body 100 is made up of the aluminium alloy layer 120 of aluminium alloy core 110 and first, wire sheet
Each part in body 100 is that aluminium alloy is made, and is not in magnetic hystersis loss and eddy-current loss in alternating current circuit, with preferable
Synthesis electric conductivity.Formed in addition, lead body 100 coats aluminium alloy core 110 by the first aluminium alloy layer 120, this knot
The lead body 100 of structure has larger capacitance, can effectively improve the utilization rate of aluminium.

Property.After six the 6th aluminium alloy filaments 112 are stranded on the 5th aluminium alloy filament 111, two adjacent the 6th aluminium alloy filaments
Be not in gap between 112, compactness is good, with certain longitudinal water-blocking ability.
The first aluminium alloy layer 120 in lead body 100 is located at outside aluminium alloy core 110, it may have conductive capability.The
One aluminium alloy layer 120 is by many first aluminium alloy filaments 121 on same circumference and many structures of second aluminium alloy filament 122
Into the middle diameter of the second aluminium alloy filament 122 is small compared with the diameter of the first aluminium alloy filament 121, that is to say, that the second aluminium alloy filament
122 resistance is larger.When inside wire by transient high-current, lead body 100 will be blown, it is ensured that electrical equipment
Safety.Certainly, the second aluminium alloy filament 122 should be moderate with the difference of the first aluminium alloy filament 121, and concrete numerical value can be according to tool
Body situation is set.
The situation that lead body 100 is blown has two kinds：One is, passes through instantaneous big electricity inside the second aluminium alloy filament 122
During stream, producing larger heat makes whole lead body 100 fuse；Two are, by instantaneous big inside the second aluminium alloy filament 122
During electric current, its own is blown, and causes the effective cross section of whole lead body 100 to be accumulated and reduces, in the effect of transient high-current
Issue hot melt disconnected.
In the fusing process of lead body 100, the second aluminium alloy filament 122 is played an important role, the second aluminium alloy filament
122 distribution will directly influence the fusing speed and fusing effect of lead body 100.Therefore, in the present embodiment, such as Fig. 3 institutes
Show, the second aluminium alloy filament 122 is arranged at intervals with the first aluminium alloy filament 121, the first aluminium alloy layer 120 of this structure exists
Transient high-current by when be heated more uniform, heat can be quickly delivered on aluminium alloy cored wire, it is ensured that lead body 100 can
Quick fuse.
In the present embodiment, the first aluminium alloy filament 121 and the second aluminium alloy filament 122 are 6, the first aluminium alloy filament
121 and the second overall hexagonal structure of the first aluminium alloy layer 120 that constitutes of aluminium alloy filament 122, with preferable stability.
6 first aluminium alloy filaments 121 and 6 second aluminium alloy filaments 122 have preferably tight after being stranded in aluminium alloy core 110
Close property, this structure make it that lead body 100 takes up space minimum.
Because the first aluminium alloy layer 120 is overall hexagonal, the screen layer 220 in protective layer 200 is circular configuration, first
Gap is certainly existed between aluminium alloy layer 120 and screen layer 220.After protective layer 200 is destroyed, it is easy to be detained product in gap
Water, will directly influence wire performance and the life-span of lead body 100.Therefore, in the present embodiment, as shown in figure 1, in screen layer
Packed layer 230 is provided between 220 and lead body 100, packed layer 230 is water blocking yarn, can effectively strengthen the longitudinal water-blocking energy of wire
Power.Certainly, it may also set up water blocking yarn in the gap between the aluminium alloy layer 120 of aluminium alloy core 110 and first.
A kind of aluminium alloy conductor that the present embodiment is provided, protective layer 200 plays a protective role to lead body 100, in it
The electric field and magnetic field that the screen layer 220 in portion is produced after being powered to lead body 100 are shielded, it is to avoid external device is led
The interference of line.The aluminium alloy layer 120 of aluminium alloy core 110 and first in lead body 100 is the carrier of electric power.Lead body
100 coat the structure of aluminium alloy core 110 using the first aluminium alloy layer 120, it is possible to increase the capacitance of wire, improve the utilization of aluminium
Rate.Each part in lead body 100 is all aluminum material, is not in magnetic hystersis loss and eddy-current loss, with higher
Comprehensive benefit.In addition, when have in wire transient high-current by when, because the second alloy filament resistance is larger, can make whole
Individual lead body 100 fuses, to ensure the safety of electrical equipment.
