Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a multi-layer wear-resistant and cut-resistant cable. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering layer. This structure makes the cable have the characteristics of internal power and external insulation, which can realize the transmission of electric energy and signals. Cable is an important power and signal transmission device and is widely used in power, communication and related fields. According to different needs and uses, different types of cables can be selected to meet the requirements of practical applications. However, when laying cables, in order to facilitate the laying of cables, it is generally necessary to push the cable directly at one end of the pipeline to complete the laying of the cable. However, in the process of pushing the cable, the cable will cause friction between the cable and the inner wall of the pipeline, resulting in wear of the cable protective layer. The wear of the cable protective layer will cause the cable to have a safety hazard of easy breakage. When laying, the protective layer of the cable is generally easily scratched by sharp objects, causing the cable core to be cut, making the cable unable to transmit signals. For this reason, we propose a multi-layer wear-resistant and cut-resistant cable. Utility Model Content
