[0002] Cables are generally made of one or more mutually insulated conductors and an outer insulating protective layer. They are used to transmit electricity or information from one place to another. During the laying process of cables, the cables usually need to be pulled, which will cause a lot of friction between the surface of the cables and the surface of the ground or buildings. Therefore, the surface of the cables needs to be tested for wear resistance during cable production.

[0004] There are at least the following problems in this technology: the cable wear resistance testing equipment grinds the cable through a grinding mechanism, but the single-sided friction environment simulation test during actual use cannot fully reflect the wear resistance of the cable insulation layer, which can easily affect the judgment of the wear condition of the cable insulation layer in the actual use environment and the judgment of whether the wear resistance of the cable insulation layer is qualified. Therefore, a cable wear resistance testing device is proposed to solve the above problems. Utility Model Content
