The outer side of the outer wrapping layer 1 is provided with multiple groups of protrusions 2, and the protrusions 2 are made of polyurethane elastomer material.

[0024] Antioxidant masterbatch plastic is a tiny particle made by adding antioxidants, additives, etc. to plastics. They play the role of anti-oxidation, anti-ultraviolet radiation, flame retardant, etc. in plastic products, thereby extending the service life of plastic products. The outer wrapping layer 1 is made of antioxidant masterbatch plastic, and the outer wrapping layer 1 can wrap and protect the outer side of the cable to delay the aging speed of the cable. The outer side of the outer wrapping layer 1 is coated with a layer of titanate composite coating, which can improve the weather resistance and light stability of the cable and maintain the color and gloss of the coating for a long time, even in severe weather conditions. It can also remain stable and effectively prevent the invasion of external pollutants such as oil, water stains, etc. At the same time, it can also use natural light to help the outer side of the cable clean itself, enhance the adhesion of the coating, and improve abrasion resistance, impact strength and softness. The protrusion 2 set on the outside of the outer wrapping layer 1 adopts polyurethane elastomer material. Polyurethane elastomer is a material with strong cohesive energy and excellent wear resistance. Compared with natural rubber, its wear resistance can be improved by 2 to 10 times.
