The twisting methods of copper stranded wire mainly include the following:
one Seven Strand Twisting: This is the most common method of twisting copper wires, which involves twisting seven copper wires together at a certain angle to form a spiral structure. This twisting method enables copper stranded wires to have good tensile strength and conductivity.
two Twelve strand stranding: Similar to seven strand stranding, it only increases the number of copper wires to twelve. This twisting method is suitable for situations that require higher tensile strength and conductivity.
three Nineteen strand stranding: Twisting nineteen copper wires together at a certain angle to form a multi strand stranded wire. This twisting method can further improve the tensile strength and conductivity of copper stranded wires.
four 37 strand twisting: This twisting method involves twisting 37 copper wires together, suitable for high strength and high conductivity requirements in special occasions.
five 61 strand stranding: Twisting 61 copper wires together to form a thicker copper stranded wire. This twisting method can meet the needs of extremely high current loads and high-voltage transmission scenarios.
six High speed cage twisting machine: This is a twisting method that uses a high-speed cage twisting machine to automatically complete the twisting, untwisting, and winding process of copper wire. It has the characteristics of high production efficiency and stable twisting quality.
seven Cold press welding stranding: During the stranding process, cold press welding technology is used to weld copper wires together to form copper stranded wires. This twisting method can make the copper stranded wire joint firm, with good conductivity and less prone to breakage.
The above twisting methods can be selected according to different application scenarios and needs. In actual production, the selection of stranding methods should be comprehensively considered in conjunction with the specifications, uses, and performance requirements of copper stranded wires.
