| titleOfInvention | Flexible stranded conductor manufacturing process and stranded conductor |
| abstract | The invention discloses a manufacturing process of a soft stranded conductor and the stranded conductor, comprising the steps of casting an aluminum alloy ingot; manufacturing an aluminum alloy rod with the diameter of 15mm by adopting a continuous casting and rolling method; drawing an aluminum alloy rod with the diameter of 15mm into an aluminum alloy single wire with the diameter of 3mm, and drawing the aluminum alloy single wire with the diameter of 3mm into an aluminum alloy filament with the diameter of 0.1 mm; adopting a bunching machine with an active pay-off device to bunch a plurality of strands of aluminum alloy filaments with the diameter of 0.1mm into a conductor unit; twisting the bundled conductor units to form a twisted conductor; annealing, the aluminum alloy material adopted by the invention has lower density, and the soft stranded conductor has lighter weight under the condition that the conductors have the same direct current resistance; the diameter of the single wire of the aluminum alloy conductor is reduced from 0.30mm to 0.10mm, so that the stranded conductor has soft bending performance; the conductor twisting adopts the processes of homodromous beam twisting and complex twisting, and simultaneously adopts the special manufacturing process of firstly beam twisting and then annealing, thereby ensuring the electrical property and the mechanical property of the product. |
