Embodiment 1
[0018] The manufacturing method of the small-pitch aluminum stranded wire has the following steps:
[0019] 1. Take the aluminum core reel with aluminum single wire as the core wire, place the aluminum core reel on the pay-off machine of the fork-type stranding unit, take six aluminum single-wire reels and place them on the wire support frame of the fork-type stranding unit,
[0020] 2. Lead the core wire out from the aluminum core wire reel on the wire pay-off machine, and enter the wire take-up machine through the shaft tube of the wire support frame, the parallel mold, and the tractor in turn, and lead the aluminum wire out of the aluminum single wire reel on the wire support frame. Respectively pass through the uniformly distributed wire holes on the outer circumference of the distribution board, enter the paralleling mold from the entrance of the paralleling mold and merge the core wires in the paralleling mold, and then enter the wire take-up machine through the tractor. ...
Embodiment 2
[0031] The manufacturing method of the small-pitch aluminum stranded wire has the following steps:
[0032] Two steps were repeated after step 4. In the two steps repeated after step 4, 17 and 21 aluminum single wire reels were respectively placed on the wire support frame, and the others were the same as in embodiment 1.
[0033] The small-pitch aluminum stranded wire produced in Example 2 is one core wire, and there are four layers outside the core wire of the small-pitch aluminum stranded wire, and the number of aluminum wires in each layer of the small-pitch aluminum stranded wire is respectively It is 6, 12, 17 and 21, and the conductive cross section of the aluminum stranded wire is 400 square millimeters.
Embodiment 3
[0035] The manufacturing method of the small-pitch aluminum stranded wire has the following steps:
[0036] In step 1, take the twisted wires of three aluminum wires as the aluminum core coil of the core wire, repeat two steps after step 4,
[0037] In step 1, step 4 and the two steps repeated after step 4, 9, 15, 20 and 22 aluminum single-wire reels were respectively placed on the wire support frame, and the others were the same as in embodiment 1.
[0038] The small-pitch aluminum stranded wire manufactured in Example 3 has three core wires, and there are four layers outside the core wire of the small-pitch aluminum stranded wire. 9, 15, 20, 22, the conductive cross-section of the aluminum stranded wire is 500 square millimeters.
