[0003] However, the existing wear-resistant cables do not have good extrusion resistance. When used on construction sites or mines, they are easily squeezed by objects such as stones from the outside, which in turn damages the cable core inside the cable, resulting in overall damage to the cable and affecting the overall performance of the cable. people's construction

The present invention discloses an extrusion-resistant and wear-resistant cable which comprises a cable main body, the cable main body comprises an outer layer, a middle layer and an inner layer, the middle layer is arranged on the outer side of the inner layer, the outer layer is arranged on the outer side of the middle layer, the middle layer comprises a filling layer located on the outer side of the outer layer, and a compression-resistant assembly is arranged in the filling layer. The filling layer is made of a high-temperature-resistant fireproof material. No matter where the arc-shaped net is stressed, the structure of the arc-shaped net can disperse pressure outwards, the second pressure-resistant units are tightly attached to each other and balance each other, so that the pressure can be effectively dispersed, and the arc-shaped net recovers elasticity when the pressure is finished, so that the pressure is reduced, and if pressure is applied to the branch net in the second compression-resistant unit, the branch net is stressed to move downwards, so that the arc-shaped net in the first compression-resistant unit is stressed and compressed, then the decomposition of the force is completed in the same way, the first compression-resistant unit and the second compression-resistant unit are mutually supported and matched, and the compression-resistant capability of the cable main body can be effectively enhanced.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to an extrusion-resistant and wear-resistant cable. Background technique [0002] Cables are usually twisted by several or groups of wires (at least two wires in each group). Each group of wires is insulated from each other, and the entire outer surface is covered with a highly insulating covering. The cable has the characteristics of internal energization and external insulation. Commonly used cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, wear-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. [0003] However, the existing wear-resistant cables do not have good extrusion resistance. When used on construction sites or mines, they are easily squeezed by objects such as stones from the outside, which in turn damages the cable core inside the cable, res...
