Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a high-strength wear-resistant cable. Background Technology

[0002] A cable is a conductor made of one or more insulated conductors and an outer insulating protective layer, primarily used to transmit electricity or information from one point to another. Cables typically consist of several or groups of conductors, each group insulated from the others, often twisted together around a central core, and covered entirely by a highly insulating outer layer. Types of cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, and aluminum alloy cables. They all consist of single or multiple strands of conductors and an insulating layer, used to connect circuits, electrical appliances, etc.

[0003] Some existing cables are used outdoors. Due to the installation location, outdoor cables often come into contact with the outside environment and rub against each other, which can easily lead to excessive wear of the outer sheath and damage to the cable due to internal exposure. The protection against external friction is not adequate. In response to this, this application proposes a high-strength wear-resistant cable. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength, wear-resistant cable to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

The abrasion-resistant mechanism includes a plurality of sets of high-strength abrasion-resistant protrusions fixedly disposed on the outer wall of the conductor and arranged in a circumferential array, lifting holes opened in the high-strength abrasion-resistant protrusions, and a plurality of inner protrusions fixedly disposed on the outer wall of the conductor and located in the lifting holes. A steel wire rope extending to the outer sheath at both ends is fixedly disposed in the high-strength abrasion-resistant protrusions.

[0007] By adopting the above technical solution, the high-strength wear-resistant bumps can rub against external objects before the outer sheath, thereby improving the wear resistance of the cable. The lifting holes can be used to suspend the cable on large external machinery. The steel wire rope can improve the internal strength of the high-strength wear-resistant bumps, making it less likely for the high-strength wear-resistant bumps to break due to excessive force after the cable is suspended. When the high-strength wear-resistant bumps are worn, the inner bumps can rub against external objects, making it less likely for the cable to be damaged due to friction.

[0008] As a further optimization of this utility model, the wire core includes a conductor, an inner insulation layer, and a shielding layer arranged sequentially from the inside out.

[0009] By adopting the technical scheme, the inner insulation layer can insulate and protect the conductor, and the shielding layer can shield and protect the conductor, so that external signals are less likely to interfere with the conductor.

[0010] As a further optimization scheme of the utility model, the inner sheath is provided with a filling layer filled in the gap between the inner wall of the inner sheath and the outer wall of the core.

[0011] By adopting the technical scheme, the inner sheath can protect the inside of the cable, and the filling layer can fill the gap in the inside of the cable, thereby improving the compression resistance and mechanical strength of the cable.

[0012] As a further optimization scheme of the utility model, the outer wall of the inner sheath is fixedly provided with an armor layer.

[0013] By adopting the technical scheme, the armor layer has the advantages of protecting the cable, enhancing the mechanical strength, and grounding protection.

[0014] As a further optimization scheme of the utility model, the gap between the inner wall of the outer sheath and the outer wall of the armor layer is fixedly provided with an outer insulation layer.

[0015] By adopting the technical scheme, the outer sheath can protect the inside of the cable, and the double-layer insulation protection of the outer insulation layer and the inner insulation layer can improve the insulation effect of the cable.

[0016] As a further optimization scheme of the utility model, the inner wall of the outer sheath is fixedly provided with a plurality of annular steel belts embedded in the inner insulation layer, and the two ends of the steel wire rope are fixedly connected with the outer wall of the annular steel belt.

[0017] By adopting the technical scheme, the annular steel belt can connect the inside of the cable and the steel wire rope, and support the hoisted cable by the annular steel belt, so that the hoisted cable is less likely to break and fall off.

[0018] The utility model has the advantages of:

[0019] 1. The high-strength wear-resistant protrusions are arranged first to rub against external objects, thereby improving the wear resistance of the cable, the lifting holes can be used to hoist the cable on large-scale mechanical equipment in the external environment, the installation is convenient, the steel wire rope can improve the internal strength of the high-strength wear-resistant protrusions, so that the high-strength wear-resistant protrusions are less likely to break due to excessive stress after the cable is hoisted, and the inner protrusions can rub against external objects after the high-strength wear-resistant protrusions are worn, so that the cable is less likely to cause damage to the external wrapping layer due to friction, thereby improving the external strength of the cable and prolonging the service life of the cable.
