Description

Compression-resistant and wear-resistant overhead cable

Technical Field

The utility model relates to the technical field of power transmission cables, in particular to a compression-resistant and wear-resistant overhead cable.

Background

The overhead cable is an overhead conductor with an insulating layer and a protective sheath, is a special cable manufactured by adopting a cross-linked cable production process, is a new power transmission mode between the overhead conductor and an underground cable, and has wide power transmission application at home and abroad.

With the progress of science and technology and the development of economy, the overhead cable is paved to all corners of the country, the body and the shadow of the overhead cable are not seen in some mountains, forests and various scenic spots, the overhead cable placed in the places is mostly lovely by birds, the birds often camp on the cable, meanwhile, some birds often camp on the cable and polish the claws and the beaks of the birds on the cable, and the common overhead cable has a single protection layer as protection, so that the overhead cable is easily damaged when the birds camp on the nest, polish the claws and the beaks, thereby influencing the transportation of electric energy.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide the overhead cable which is firm in structure, wear-resistant, compression-resistant and better in performance.

In order to achieve the above purpose, the utility model provides a compression-resistant and wear-resistant overhead cable, which comprises four cable cores, wherein the cable cores are wrapped with first insulating layers; reinforcing ribs are arranged in the middle of the four cable cores; steel wires are wound outside the four cable cores; the cable core outside still includes from interior to outside parcel second insulating layer, armor that sets up in proper order and protective layer.

Preferably, the armor layer is a metal tape armor.

Preferably, the rectangular cable core array is arranged outside the reinforcing ribs; the steel wires are wound and wrapped outside the four cable cores.

Preferably, the reinforcing ribs are formed by winding tensile steel wires.

The utility model has the beneficial effects that: according to the utility model, the reinforcing ribs are arranged in the middle of the cable cores and serve as the main axle center of the whole cable, so that the whole compression-resistant bending capacity of the overhead cable is enhanced, meanwhile, the cable is wound and tightly wrapped together through the steel wires and the reinforcing ribs, so that the cable structure is more compact, the compression-resistant capacity is stronger, meanwhile, the armor layer is additionally arranged outside the cable cores and is a metal tape armor, the wear-resistant capacity of the cable is improved, the use is firmer, the protection layer is worn in time, the metal tape armor can provide further protection for the inner cable cores, and the normal work of electric power energy transportation is ensured.
