The utility model provides a cable. In the prior art, an anti-interference capability of the cable is poor and waterproofness of the cable is poor too. By using the cable of the utility model, the above problems are solved. The cable comprises at least two wire core conductors, an insulating layer, a wrapping tape, an inner sheath layer and an outer sheath layer, wherein the insulating layer is arranged outside the wire core conductors; an antimagnetic layer used for reducing an electromagnetic interference between adjacent wire core conductors is arranged between the wire core conductors and the insulating layer; the wrapping tape is used to fix the wire core conductors and is arranged outside the insulating layer; the inner sheath layer achieves waterproof and anticorrosion effects and is arranged outside the wrapping tape; the outer sheath layer achieves a protection effect and is arranged outside the inner sheath layer. Through arranging the antimagnetic layer and the insulating layer, the interference among the wire core conductors can be effectively reduced; through designing a filling layer, the wrapping tape, the inner sheath layer, an armor layer and the outer sheath layer, the good waterproof effect is achieved, wear resistance and mechanical stretching resistance effects are possessed so that whole cable performance is good.

Description

A kind of cable

Technical field

The utility model power transmitting device technical field, refers to a kind of cable especially.

Background technology

At present, along with socioeconomic development, people's routine work, life, productive power amount increase day by day, therefore also increasing for power transmission cable use amount, but some cable use occasion becomes increasingly complex, such as wet environments such as harbour, harbour, hydroelectric station, reservoir, tunnels, in these situations, cable, except possessing anti-mechanical damage function, also should possess good fire resistance characteristic.Existing cable cover(ing) is owing to lacking good permeability resistance, and water is easy to penetrate into cable inside, and the insulating barrier of parcel core is caused to potential destruction, affects the useful life of cable, when serious, can cause cable cisco unity malfunction.

In addition, the structure of existing cable is generally mainly multiple cores and is directly wrapped in insulating material, does not have spacing between adjacent core, like this in the time that unlike signal transmits in core separately, between different signals, unnecessary electromagnetic interference can occur, the resistance to compression resistance to tension of cable is also poor.

Utility model content

The utility model proposes a kind of cable, solved cable poor anti jamming capability of the prior art, the poor problem of water resistance.

The technical solution of the utility model is achieved in that

A kind of cable, comprising:

At least two core conductors;

Insulating barrier, is arranged on outside core conductor, wherein, is also provided with the anti-magnetosphere for reducing electromagnetic interference between adjacent lines core conductor between core conductor and insulating barrier;

For the take-up strap of fixing several threads core conductor, be arranged on outside insulating barrier;

Be used for the sheath of waterproof, corrosion-resisting function, be arranged on outside winding layer;

For the external sheath layer shielding, be arranged on outside sheath.

As further technical scheme, between the insulating barrier outside each core conductor and take-up strap, be also provided with packed layer.

As further technical scheme, the filler of packed layer is waterproof rope.

As further technical scheme, also comprise: armour, is arranged between sheath and external sheath layer.

As further technical scheme, armour is zinc-plated steel band armour.

As further technical scheme, sheath is polyolefin sheath.

As further technical scheme, external sheath layer is PVC thermoplastic plastic layer, and its thickness is for being not less than 5 millimeters.

The insulating barrier that is arranged on the anti-magnetosphere outside core conductor and be arranged on outside anti-magnetosphere can effectively reduce the interference between each core conductor; The take-up strap being arranged on outside insulating barrier can make several core conductors that added insulating barrier fix; , be arranged on the concrete anti-flaming effect of packed layer between insulating barrier and take-up strap; Sheath is arranged on outside take-up strap, has good waterproof, corrosion-resisting function; Armour is arranged on outside sheath, has the effect of anti-destruction and anti-mechanical stretching; External sheath layer, is arranged on armour, plays good physically encapsulation and good resistance to wear.

In sum, by being set, anti-magnetosphere and insulating barrier can effectively reduce the interference between each core conductor; By the design of packed layer, take-up strap, sheath, armour and external sheath layer, not only play very high waterproof action, and there is wear-resisting, anti-mechanical stretching effect, and then make whole cable performance better.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the cross sectional representation of the utility model embodiment;

In figure:

1, core conductor; 2, diamagnetic layer; 3, insulating barrier; 4, packed layer; 5, take-up strap; 6, sheath; 7, armour; 8, external sheath layer.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
