Description

A kind of cable with waterproof construction

Technical field

The utility model belongs to field of cable technology, and in particular to a kind of cable with waterproof construction.

Background technique

New energy is greatly developed, so that wind energy and the utilization rate of solar energy are higher and higher, solar energy and wind-force hair Motor group needs matched cable to arrange in pairs or groups.

However existing cable is there is lead to the problem of cable noise when deficiency and wireline operation in terms of waterproof.

Utility model content

The purpose of this utility model is to provide a kind of cables with waterproof construction, to solve to mention in above-mentioned background technique Existing cable out is there is lead to the problem of cable noise when deficiency and wireline operation in terms of waterproof.

To achieve the above object, the utility model provides the following technical solutions: a kind of cable with waterproof construction, including Conductor thread core and outer protecting shell, the lateral surface of the conductor thread core are extruded with inner conducting layer, and the lateral surface of the inner conducting layer extrudes There is insulating layer, the lateral surface of the insulating layer is extruded with outer conducting layer, and the lateral surface of the outer conducting layer is surrounded with outer conductive strips, It is extruded with metal screen layer on the outside of the outer conductive strips, waterstop is surrounded on the outside of the metal screen layer, it is described to block water Oversheath is extruded on the outside of band.

Preferably, the outer protecting shell is extruded in the outside of oversheath.

Preferably, the inside of the oversheath is filled with silencing cotton.

Preferably, the outer protecting shell is steel bushing.

Preferably, the oversheath is high-density polyethylene outer sheath.

Compared with prior art, the utility model has the beneficial effects that

(1) by waterstop, high-density polyethylene outer sheath and the steel bushing of design, so that cable has extraordinary diameter To block-water performance；

(2) inside of oversheath is filled with silencing cotton, using the effect of silencing cotton noise reduction, reduces the thermal effect because of cable material It answers or the cable noise of the generations such as the piezoelectric effect of cable dielectric material.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of technical solution: a kind of cable with waterproof construction, including Conductor thread core 4 and outer protecting shell 1, the lateral surface of conductor thread core 4 are extruded with inner conducting layer 5, reach conductive effect by inner conducting layer 5 Fruit, the lateral surface of inner conducting layer 5 are extruded with insulating layer 3, and insulating layer 3 is not bad by armour skin lesion when making cable armouring, insulating layer 3 Lateral surface is extruded with outer conducting layer 6, it is ensured that the effect of cable conduction, the lateral surface of outer conducting layer 6 are surrounded with outer conductive strips 7, outside Conductive strips 7 have fabulous anti-flammability, and the outside of outer conductive strips 7 is extruded with metal screen layer 2, the electric current ratio that power cable passes through It is larger, magnetic field can be generated around electric current, in order to not influence other element, add metal screen layer 2 can be this electromagnetic-field-shielded In cable, breakage occurs in cable core, the electric current leaked can play peace along the stream of metal screen layer 2 such as grounded screen The effect of full guard, the outside of metal screen layer 2 are surrounded with waterstop 8, and the outside of waterstop 8 is extruded with oversheath 9, utilizes resistance Water band 8 further functions as the effect to block water.

In the present embodiment, it is preferred that outer protecting shell 1 is extruded in the outside of oversheath 9, using outer protecting shell 1, for 19kV grades with For upper XLPE insulated cable, then mainly cable is set to reach waterproof requirement, the maximum of metal sheath using metal sheath outer protecting shell 1 Feature is that have complete impermeability.

In the present embodiment, it is preferred that the inside of oversheath 9 is filled with silencing cotton 10, using the effect of 10 noise reduction of silencing cotton, Cable noise of the reduction because of the generations such as the fuel factor of cable material or the piezoelectric effect of cable dielectric material.

In the present embodiment, it is preferred that outer protecting shell 1 is steel bushing, using it with complete impermeability, therefore has protective metal shell Cable have extraordinary radial water-resisting performance.

In the present embodiment, it is preferred that oversheath 9 is high-density polyethylene outer sheath, has good electrical property, especially Dielectric strength is high, waterproof, anticorrosion.

The working principle and process for using of the utility model: the wrapped waterstop 8 in the outside of metal screen layer 2, waterstop 8 Outside is extruded with oversheath 9, and the effect to block water is further functioned as using waterstop 8；

Outer protecting shell 1 is extruded in the outside of oversheath 9, and using outer protecting shell 1,19kV grades or more XLPE insulated cable is come It says, then mainly so that cable is reached waterproof requirement using metal sheath outer protecting shell 1, the maximum feature of metal sheath is that have completely not Permeability；

Silencing cotton 10 is filled in the inside of oversheath 9, using the effect of 10 noise reduction of silencing cotton, reduces the thermal effect because of cable material It answers or the cable noise of the generations such as the piezoelectric effect of cable dielectric material.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
