[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Figure 1-4 As shown, the utility model provides a rare earth aluminum alloy welding machine cable, which includes a conductor body 1. The outer side of the conductor body 1 is covered with an insulating layer 2. The conductor body 1 is made of rare earth aluminum alloy monofilaments added with nylon fibers and bundled.

[0023] Specifically, the conductor body 1 utilizes a Class VI rare earth aluminum alloy soft conductor, constructed from 63% IACS rare earth aluminum alloy rods that are drawn, then subjected to a multi-stage aging annealing at 360°C. Nylon fibers are added during the filament bundling process for reinforcement. This construction offers the advantage of combining multi-stage aging annealed rare earth aluminum alloy monofilaments with nylon fibers, resulting in a Class VI aluminum alloy soft conductor. The nylon fibers enhance the conductor body's strength, achieving a conductivity of 63.0% IACS. This increases the cable's current carrying capacity while also making it more flexible and resistant to bending, tension, and torsion.

[0024] Specifically, the conductor body 1 includes chemical components such as Si (0.042%), Fe (0.154%), Ca (0.013%), Cu (0.002%), Mn (0.0053%), V (0.078%), Ti (0.013%), and rare earth (0.103%). Advantageously, the inclusion of multiple chemical components in the conductor body 1 provides excellent resistance to bending fatigue, tension, and torsional stress.

[0025] Specifically, the single-strand pitch of the conductor body 1 is less than 16 times the outer diameter, and the twist pitch of the conductor body 1 is less than 12 times the outer diameter. Advantageously, the dense arrangement of the conductor bodies 1 helps reduce the impact of external stress on the conductor body, reducing stretching and twisting of the conductor body during use, thereby extending the service life of the cable and improving its durability and reliability. Besides being more flexible, the composite structure of the conductor body 1 also has at least twice the mechanical properties of a normal conductor.

[0026] Example 2: Figure 2-4 As shown, it is an improvement to the previous embodiment.

[0027] Specifically, the insulating layer 2 is made of super wear-resistant and flame-retardant TPU insulating material. Advantages are that the insulating layer 2 is made of super wear-resistant and flame-retardant TPU insulating material, which has excellent insulation performance, high temperature resistance, wear resistance, flame retardancy, high elasticity and extremely high flexibility.

[0028] Working principle: The conductor body 1 adopts a Class 6 aluminum alloy soft conductor composed of multi-stage aging annealing rare earth aluminum alloy monofilament and nylon fiber filament. The nylon fiber improves the strength of the conductor body and the electrical conductivity reaches 63.0% IACS, which makes the cable softer, more resistant to bending, tension and torsion while increasing the current carrying capacity. The conductor body 1 is arranged tightly, which helps to reduce the impact of external stress on the conductor body and reduce the stretching and twisting of the conductor body during use, thereby extending the service life of the cable and improving its durability and reliability. In addition to being softer, the composite structure of the conductor body 1 also has at least twice the mechanical properties of normal conductors. The insulation layer is made of super wear-resistant and flame-retardant TPU insulation material, which has excellent insulation performance, high temperature resistance, wear resistance, flame retardancy, high elasticity and extremely high flexibility. This rare earth aluminum alloy welding machine cable has the characteristics of lower cost, high strength, super flexibility, super wear resistance and flame retardancy; it is the best choice to replace copper core welding machine cable.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
