Abstract
The utility model provides a novel single-core cross-linked armored cable, which comprises a metal conductor. The outside of the metal conductor is provided with a conductor shielding layer. The outside of the conductor shielding layer is coated with an insulating layer. The outside of the insulating layer is provided with an insulation shielding layer. The outside of the insulation shielding layer is provided with a steel-tape shielding layer. The outside of the steel-tape shielding layer is coated with non-woven fabric. The outside of the non-woven fabric is provided with an inner sheath. The outside of the inner sheath is provided with a steel-tape armoring layer. The outside of the steel-tape armoring layer is provided with an outer sheath. The metal conductor is in the form of a copper conductor or a tin-plated copper conductor. In order to improve the anti-interference capability of the cable, copper wires are uniformly distributed in the steel-tape armoring layer. The novel single-core cross-linked armored cable has the advantages of novel structure, high temperature resistance and aging resistance.
Description
Technical field
The utility model relates to the power cable field, is specifically related to a kind of novel single-core crosslinked insulation polyethylene armoured cable.
Background technology
power cable is a kind of cable for transmission and distribution electric energy, in communication industry, car industry, power industries etc. have a wide range of applications, traditional power cable insulation material generally adopts common PVC, heat-resisting, the acid-alkali-corrosive-resisting poor performance, usually the power cable overload current is large, voltage is high, when the temperature of conductor arrive 70 degree when above insulation PVc thermal deformation easily occurs, thermal breakdown even occurs, insulation property reduce greatly, time one length also can form cracking phenomena, the fail safe of cable can not get ensureing, the appearance of crosslinked polyethylene insulation material has made up the deficiency of traditional material, has good heat resistance, the routine work temperature can reach 90 ℃, good pressure-resistant performance has operating pressure 12.5bar and two grades of 20bar under normal temperature, the characteristics such as corrosion-resistant.
Generally all be laid in open air or be embedded in soil of power cable easily suffers the destruction of mechanical external force and biting of mouse, and after cable adds steel-tape armouring, the external force resistance performance significantly improves, and has extended the useful life of cable.
The utility model content
To be solved in the utility modelly be: the utility model provides a kind of novel structure, high temperature resistant, ageing-resistant single-core crosslinked polyethylene insulation armoured cable, and it can also prevent machinery with the destruction of animal, good insulation preformance, long service life.
The technical solution of the utility model is as follows:
A kind of novel single-core crosslinked insulation polyethylene armoured cable, comprise metallic conductor, be provided with conductor shield outside described metallic conductor, be wrapped with insulating barrier at described conductor shield, be provided with insulation screen outside described insulating barrier, insulation screen is provided with the steel band screen outward, the steel band screen is wrapped with nonwoven fabrics, nonwoven fabrics is provided with inner sheath outward, and inner sheath is provided with steel-tape armouring outward, and steel-tape armouring is provided with oversheath outward.
Described metallic conductor is copper conductor or tinned copper conductor.
In order to improve the antijamming capability of cable, described steel-tape armouring is evenly distributed with copper wire.
Described insulating barrier adopts cross-linking polyethylene materials to make.
Beneficial effect: a kind of novel single-core crosslinked insulation polyethylene armoured cable novel structure described in the utility model, high temperature resistant, ageing-resistant, it can also prevent machinery with the destruction of animal, good insulation preformance, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, metallic conductor 2, conductor shield 3, insulating barrier 4, insulation screen 5, steel band screen 6, nonwoven fabrics 7, inner sheath 8, steel-tape armouring 9, copper wire 10, oversheath
Embodiment
As shown in Figure 1, a kind of novel single-core crosslinked insulation polyethylene armoured cable, comprise copper conductor, be provided with conductor shield outside described copper conductor, be wrapped with at described conductor shield the insulating barrier that cross-linking polyethylene materials is made, be provided with insulation screen outside described insulating barrier, insulation screen is provided with the steel band screen outward, the steel band screen is wrapped with nonwoven fabrics, nonwoven fabrics is provided with inner sheath outward, inner sheath is provided with steel-tape armouring outward, is evenly distributed with copper wire in steel-tape armouring, and steel-tape armouring is provided with oversheath outward.Adopt the single-core crosslinked polyethylene insulation armoured cable of the utility model embodiment, novel structure, high temperature resistant, ageing-resistant; It can also prevent machinery with the destruction of animal, good insulation preformance, long service life; And advantages of good shielding performance, not easy electromagnetic wave interference
