Abstract

An armor power cable comprises a conductor. An insulating layer wraps the conductor in an extruding mode. An inner protection cover layer is arranged outside the insulating layer. A wire armoring layer is arranged outside the inner protection cover layer in a sub-thread spirally twisted mode, an outer protection cover layer is arranged outside the wire armoring layer, and a padding rope is arranged between the insulating layer and the inner protection cover layer. The armor power cable is corrosion resistant, high in strength, deformation resistant and long in service life, and can be prevented from being damaged by subterranean animals and machines when underground machines work.

Description

A kind of armoured power cable

Technical field

The present invention relates to power cable field, be specifically related to a kind of novel armoured power cable.

Background technology

Power cable is a kind of for transmitting and distribute the cable of electric energy, in communication, the all trades and professions such as civilian have a wide range of applications, the power cable insulation material of selling on open market adopts common PVC, external intensity poor performance, work as bearing great current, during high-tension work, external insulation easily deforms, even puncture, insulation property are affected, after working long hours, may affect electric power transfer effect, even there is security incident, particularly cable is generally all embedded in soil, in road trimming or while again constructing, very easily suffer the destruction of the subteranean animals such as the destruction of the mechanical external forces such as excavator or mouse.

Summary of the invention

For above defect, the invention provides a kind of novel armoured power cable, corrosion-resistant, intensity is high, anti-deformation, long service life, the mechanical damage in the time of particularly can preventing underground mechanical execution and the destruction of subteranean animal.

Technical scheme of the present invention is as follows:

A kind of novel armoured power cable, it is characterized in that: it comprises conductor, at described conductor, be extruded with insulating barrier outward, at described insulating barrier, be provided with inner restrictive coating outward, outside described inner restrictive coating, sub-thread revolves strand wire armoring layer, at described wire armoring layer, be also provided with external sheath layer outward, between described insulating barrier and inner restrictive coating, be also provided with gasket for packing.

Described conductor is bright copper conductor.

Described cross-sectional area of conductor is that 180 degree are fan-shaped.

Described insulating barrier adopts cross-linking polyethylene materials.

Described wire armoring layer adopts galvanized steel bar silk.

Beneficial effect: a kind of novel armoured power cable provided by the invention, corrosion-resistant, intensity is high, anti-deformation, long service life, the mechanical damage in the time of particularly can preventing underground mechanical execution and the destruction of subteranean animal.

accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

In figure: 1, conductor 2, insulating barrier 3, gasket for packing 4, inner restrictive coating 5, wire armoring layer 6, external sheath layer.

Embodiment

As shown in Figure 1: a kind of novel armoured power cable, it comprises conductor 1, and described conductor 1 is bright copper conductor, and conductor 1 cross section is that 180 degree are fan-shaped; Outside described conductor 1, be extruded with insulating barrier 2, insulating barrier 2 adopts cross-linking polyethylene materials; Outside described insulating barrier 2, be provided with inner restrictive coating 4, at the outer sub-thread of described inner restrictive coating 4, revolve strand and have wire armoring layer 5, wire armoring layer 5 adopts galvanized steel bar silk, outside described wire armoring layer 5, be also provided with external sheath layer 6, between described insulating barrier 2 and inner restrictive coating 4, be also provided with gasket for packing 3.

Use armoured power cable provided by the invention, corrosion-resistant, intensity is high, anti-deformation, long service life, the mechanical damage in the time of particularly can preventing underground mechanical execution and the destruction of subteranean animal.
