Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a flexible wear-resistant cable for an electric welding machine. Background Art

[0002] The cables used in welding machines often need to be used in more complex environments. These cables are usually made of multiple copper wires twisted together to form a thick wire body to ensure that large currents can be transmitted. In addition, the conductor of the cable is insulated with a layer of heat-resistant polyester film. The friction between the cable and external objects often causes the cable surface to wear. After the cable is worn, the cable core is easily affected by the outside world, which affects the service life of the cable. After the cable is bent, the cable is severely deformed, which can easily cause the cable to break and be damaged, and the protection effect is low. Utility Model Content
