However, the annealing process of the bimetallic conductor is obviously different from that of copper-aluminum single conductor.
Annealing of copper wire at any point in the range of several hundred degrees above the recrystallization temperature to below the melting point will not cause quality accidents and is not very sensitive to temperature fluctuations. However, the ECCA line has strict limits on furnace temperature, and the temperature difference between the conduits must not be too different. Water-sealed copper wire annealing furnace with wire tubes as heating elements has a different distribution of temperature field for each wire tube after furnace temperature is balanced because it is a... less
