Abstract
The utility model relates to a cable, in particular to a novel smooth-type aluminum-sheathed cable, which comprises a cable conductive body and an insulating layer arranged on the outer layer of the cable conductive body. The novel cable is characterized in that a semi-conductive buffer strip or a semi-conductive buffer waterstop strip is wound at the outer part of the insulating layer; a smooth-type aluminum sheath is arranged on the outer layer of the semi-conductive buffer waterstop strip; and an outer sheath is arranged on the outer layer of the smooth-type aluminum sheath. The novel cable provided by the utility model has the advantages that capacitive electric discharge of the cable can be reduced, the service life of the product is prolonged, the laying of the cable is convenient, the utilization amount of the material is lowered, and the resource is saved.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of novel smooth type aluminum-sheathed cable.
Background technology
As everyone knows, the above crosslinked cable of China 66kV adopts ripple type aluminium nested structure (claiming corrugated aluminium sheath again) basically at present.The aluminium cover of cable mainly plays the carrying short circuit current, radially blocks water the effect of electric field shielding and carrying exterior mechanical stress.
Mainly there is following defective in traditional ripple type aluminium cover construction of cable: 1, traditional ripple type aluminium cover cable aluminium cover is ripple type, and the aluminium cover contacts to the contact of linear point with insulated wire cores, is prone to capacitive discharge in the process of test; 2, ripple type aluminium cover needs to prick line, and external diameter must be done very greatly, waste material.3, owing to have certain space between corrugated aluminium cover and the insulated wire cores, the whole cable structure is compact inadequately, and vertically block-water performance is very poor.
Summary of the invention
The utility model mainly is at the above-mentioned technical problem of existing in prior technology, a kind of capacitive discharge that can reduce cable is provided, improves life of product, is convenient to the novel smooth type aluminum-sheathed cable that material usage, energy savings were laid, reduced in cable construction.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of novel smooth type aluminum-sheathed cable, comprise cable conductor, the cable conductor skin is arranged with insulating barrier, it is characterized in that outside wrapped semi-conductive buffer band of described insulating barrier or semi-conductive buffer water-blocking band, described semi-conductive buffer water-blocking band skin is arranged with smooth type aluminium cover, and described smooth type aluminium cover skin is arranged with oversheath.On the basis of primary aluminum cover, change traditional ripple type aluminium cover into smooth type aluminium cover, do not change original performance of cable, reach the effect of energy-saving consumption-reducing.
As preferably, described insulating barrier both sides are laid with inner shield and external shield respectively.Simple in structure, safe and reliable.
As preferably, described smooth type aluminium cover outer surface is laid with cable pitch.Rational in infrastructure, easily manufactured, long service life.
As preferably, described oversheath surface is provided with semi-conductive layer.Can reduce the capacitive discharge of cable effectively.
Therefore, the utlity model has the capacitive discharge that can reduce cable, improve life of product, be convenient to cable construction and lay, reduce characteristics such as material usage, energy savings.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1, a kind of novel smooth type aluminum-sheathed cable, comprise cable conductor 1, the cable conductor skin is arranged with insulating barrier 2, the outside wrapped semi-conductive buffer water-blocking band 3 of insulating barrier, the semi-conductive buffer water-blocking band skin is arranged with smooth type aluminium cover 4, and smooth type aluminium cover skin is arranged with oversheath 5.The insulating barrier both sides are laid with inner shield and external shield respectively.Smooth type aluminium cover outer surface is laid with cable pitch.The oversheath surface is provided with semi-conductive layer.
On the basis of primary aluminum cover, change traditional ripple type aluminium cover into smooth type aluminium cover, do not change original performance of cable, reach the effect of energy-saving consumption-reducing.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
