[0002] Cable refers to materials used for power, communication and related transmission purposes. With the continuous expansion of the power industry and data communication, the demand for cables is also growing rapidly. Shielded cable refers to a shielding layer wrapped around the cable insulation layer to reduce external interference to the cable inside the insulation layer, and also reduce the influence of the magnetic field generated by the current in the insulation layer on the outside world.

[0003] Existing shielded cables are usually equipped with an armor layer inside, which can reduce the incidence of rats biting the cable core, but it cannot completely eliminate this hidden danger. The rat-proof effect of the cable needs to be improved. Therefore, it is necessary to propose a rat-proof and ant-proof shielded cable to solve the above-mentioned problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model can increase the wear resistance of the cable through the cable wear-resistant layer to prevent the cable from breaking during the friction with the ground. The first protective layer and the second protective layer are both made of polyvinyl chloride.
