Description

technical field [0001] The invention relates to a stranding machine, in particular to an online heat treatment device for a cable stranding machine which completes the annealing process. Background technique [0002] At present, the cable manufacturing industry mostly adopts compaction process to produce cable conductors, and the existing stranding machine can realize the compaction production of cable conductors. However, the cable conductors produced by this process have problems such as conductor hardening and resistivity rise. In order to make the produced cables meet the product standards, the cable conductors produced by the compression process must increase the cross-sectional area to meet the product standards. Increase the cost of cable production. In order to solve the above problems, the production of cables requires annealing treatment. After the existing annealing treatment, cooling water is used to cool down the temperature and then the cables are directly rec...

AI Technical Summary

Problems solved by technology

However, the cable conductors produced by this process have problems such as conductor hardening and resistivity rise. In order to make the produced cables meet the product standards, the cable conductors produced by the compression process must increase the cross-sectional area to meet the product standards. Increased cost of cable production

In order to solve the above problems, the production of cables requires annealing treatment. After the existing annealing treatment, the cable is directly recycled after cooling with cooling water. The moisture of the cable affects the performance of the cable.
