Technical Field

[0001] The utility model relates to the technical field of wires and cables, in particular to a wire and cable with a wear-resistant and pressure-resistant structure. Background Art

[0002] Wires and cables refer to materials used for power, electrical and related transmission purposes. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which consist of one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] Currently, existing wires and cables have poor surface wear resistance during use. When people lay and drag them, they are easily worn out, causing damage to the surface. At the same time, the surface is also prone to rupture when subjected to force and pressure, which seriously affects the overall safety and service life. Utility Model Content
