(2) more aluminium alloy single lines are subjected to bundle strand, wherein synnema lay ratio is not more than 30 times；
(3) multiple twist is carried out using 1+6+12 structure and is processed into aluminium alloy conductor, the 1st layer of lay ratio is not more than 20 times, and direction is the right side To the 2nd layer of lay ratio is not more than 14 times, and direction is left-hand；
(4) twisted aluminium alloy conductor is heat-treated, the heating of reply annelaing pot into 25~30min dehumidify before being switched on, and move back The temperature of fire-box is 140~150 DEG C, is then placed in aluminium alloy conductor and is heat-treated；Heat treatment temperature is 320~340 DEG C, is protected The warm time be 3.0~3.5h, tapping temperature≤150 DEG C,
Further, in the step (1) wire drawing machine using 11 assemble mould successively wire drawing to 0.493mm: every group with die hole Diameter are as follows: the 1st 1.584mm, the 2nd 1.410mm, the 3rd 1.254mm, the 4th 1.116mm, the 5th 0.993mm, the 6th 0.884mm, the 7th 0.786mm, the 8th 0.699mm, the 9th 0.623mm, the 10th 0.554mm, the 11st 0.493mm.
Further, in the pulling process wire drawing machine tension air pressure be 0.4~0.55Mpa, linear velocity be 15~ 20m/s。
Further, aluminium alloy single line 98~159MPa of tensile strength after the heat treatment, elongation >=10%, repeatedly Number of bends >=25,20≤0.028264 Ω mm of electricalresistivityρ2/m。
Preparation method of the present invention is simple, and step is easily operated, and the aluminium alloy conductor alternating bending frequency being prepared is greater than Equal to 25, creep speed is less than or equal to 1 × 10-2(%/h).The current-carrying capacity of 5th kind of aluminium alloy conductor of same cross-sectional is the 5th kind The 80% of copper conductor, i.e. the 5th of 1.25 times the kind of copper conductor section can meet current-carrying capacity identical with the 5th kind of copper conductor, and weight is anti- But the 40% of the 5th kind of copper conductor, it can effectively reduce the overall weight of cable.
