Abstract

The utility model discloses a novel crosslinked cable, comprising three conductors which are respectively provided with an insulating layer and are tangent to each other, and an inner sheath wrapping the three conductors, wherein the outer side of the inner sheath is sequentially provided with an armored layer wound by steel wires, and an outer sheath. According to the novel crosslinked cable, the structure is simple, the manufacturing cost is low, the armored layer wound by the steel wires is added between the inner sheath and the outer sheath, the radial mechanical force resistance of the novel crosslinked cable is increased, the cable can be better protected, and the service life is prolonged.

Description

A kind of novel crosslinked cable

Technical field

The utility model relates to a kind of crosslinked cable, more precisely, relates in particular to a kind of crosslinked cable with anti-radial pull.

Background technology

Crosslinked cable is meant that the insulating barrier of cable adopts cross-linked material.The most frequently used material is crosslinked polyethylene (XLPE).The crosslinking process process is that the polyethylene of linearity molecular structure (PE) material is passed through specific processing mode, makes it form the crosslinked polyethylene of netted minute line structure of build.Make the long-term working temperature that allows bring up to 90 ℃ (or higher) by 70 ℃, the short circuit allowable temperature is brought up to 250 ℃ (or higher) by 140 ℃, under the prerequisite that keeps its original superior electrical performance, has improved actual serviceability widely.Crosslinked cable generally is used for the dispensing of 8.7-15 kilovolt high-tension electricity.

Crosslinked cable of the prior art, its skin adopts cross-linking polyethylene materials, mainly bears pulling force, but in distortion or special occasions use, its anti-radial pull is not enough, and conductor is ruptured.

The utility model content

The utility model provides a kind of novel crosslinked cable in order to solve the problem that exists in the prior art, and it is simple in structure, has stronger anti-radial pull, can use at special occasions.

For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of novel crosslinked cable; Comprise three conductors that are respectively equipped with insulating barrier; Three conductors are tangent to each other, also are provided with the inner sheath with three conductor parcels, and the outside of said inner sheath is provided with armour, the oversheath that steel wire twines successively.

The crosslinked cable of the utility model, it is simple in structure, and cost of manufacture is low, between inner sheath and oversheath, has installed one deck additional by the armour that steel wire twines, and has increased its anti-radially mechanical force, can protect cable better, prolongs its useful life.

Description of drawings

Fig. 1 shows the structural representation of the utility model crosslinked cable.

Embodiment

Further specify below in conjunction with the embodiment of accompanying drawing the utility model.

With reference to Fig. 1, the crosslinked cable of the utility model, its insulating barrier are cross-linking polyethylene materials, can certainly adopt this area other cross-linked materials commonly used, are fit to the dispensing of 8.7-15 kilovolt high-tension electricity.It comprises three conductors 1 that are respectively equipped with insulating barrier 4, and wherein, conductor can adopt copper product or aluminum; Three conductors 1 are tangent to each other, are construed as between the insulating barrier that has wrapped up conductor tangent to each other here.

Also be provided with the inner sheath 8 with three conductors 1 parcel, inner sheath 8 can adopt PVC material or polyethylene, nylon material etc., mainly plays the effect of a protection.

The outside of said inner sheath 8 is provided with armour 7, the oversheath 1 that steel wire twines successively, and the material of oversheath 1 is the same with inner sheath, can be PVC, polyethylene or nylon.Between inner sheath 8 and oversheath 1, install one deck additional by the armour 7 that steel wire twines, increased its anti-radially mechanical force, can protect cable better, prolonged its useful life.

The crosslinked cable of the utility model; Between conductor 1 and insulating barrier 4, also can be provided with one deck internal shield 3; The outside of insulating barrier 4 is provided with one deck outer shielding layer 5, and said internal shield 3 can also can adopt other materials known in the art for tinned copper wire is entwined with outer shielding layer 5.Be provided with internal shield 3, outer shielding layer 5 electric field that when distribution, produces of compensating cable effectively.

The crosslinked cable of the utility model also can be provided with one deck steel band screen in the outside of outer shielding layer 5, can more effectively balanced electric field, the effect of earial drainage in addition simultaneously.

The crosslinked cable of the utility model, the cross-sectional area of conductor 1 is preferably 300mm ²Or 35mm ²

The crosslinked cable of the utility model, fill with filler 9 in the gap between three conductors 1 and the inner sheath 8, and said filler is non-hygroscopic material, such as polypropylene or glass fiber etc.

The utility model is through preferred embodiment having carried out detailed explanation.Yet, through to the studying carefully of preamble, to the variation of each execution mode with to increase also be that one of ordinary skill in the art institute is conspicuous.Applicant's intention is all these variations and increases the part in the scope of the utility model claim that all comprised dropping on of the utility model.

Similar numbering refers to similar element in the whole text.For the purpose of clear, has the situation that some line, layer, element, parts or characteristic are amplified in the accompanying drawings.

The term that uses among this paper is merely to be explained concrete embodiment, and it is not to be intended to the utility model is limited.Only if definition is arranged in addition, all terms that use among this paper (comprising technical term and scientific terminology) are all identical with the utility model one of ordinary skill in the art's understanding.

Claims

1. novel crosslinked cable, it is characterized in that: comprise three conductors that are respectively equipped with insulating barrier, three conductors are tangent to each other, also are provided with the inner sheath with three conductors parcels, and the outside of said inner sheath is provided with armour, the oversheath that steel wire twines successively.
