Abstract
The invention discloses a crosslinked polyethylene insulated power cable. The crosslinked polyethylene insulated power cable comprises a cable core, wherein a packing layer is arranged at the gap position of the cable core, a first steel-tape armoring layer and a second steel-tape armoring layer are wrapped round the outside of the cable core, an outer protective sleeve is wrapped at the outermost layer of the cable core in an extruding mode, the cable core is formed by twisting three main wire cores with sections of 4mm<2> and an auxiliary wire core with the section of 1.5mm<2>, and the main wire cores and the auxiliary wire core are identical in structure. The main wire cores and the auxiliary wire core are composed of conductors and nonlinear insulated layers which are wrapped round the outsides of the conductors in the extruding mode. According to the crosslinked polyethylene insulated power cable, the aging phenomena of crosslinked polyethylene insulated layers are improved, the working stability and the reliability of the crosslinked polyethylene insulated power cable are improved, and the service life of the cable is prolonged.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of power cable with cross-linked polyethylene insulation.
Background technology
Power cable with cross-linked polyethylene insulation because its good electric property, transmission capacity are big, can high drop or advantages such as vertical run, installation and maintenance aspect, it uses very extensive in high pressure and extra-high-tension cable field.In the practical application of power cable with cross-linked polyethylene insulation, because deterioration and destruction that reason such as aging is easy to cause crosslinked polyetylene insulated layer.By series of improving measures, still still can't eliminate the formation and development of electric branch aging phenomenon in the crosslinked polyetylene insulated layer fully in the prior art; In carrying out high pressure and superhigh pressure transmission course, because there is the potential safety hazard with cable breakdown in the decline of insulation property.Therefore, how the structure of power cable with cross-linked polyethylene insulation in the prior art is improved, to improve the aging destruction that power cable is caused of crosslinked polyetylene insulated layer, improve job stability and the reliability of power cable with cross-linked polyethylene insulation, improving the useful life of cable, is those skilled in the art's technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of power cable with cross-linked polyethylene insulation, improved the aging phenomenon of crosslinked polyetylene insulated layer, job stability and the reliability of power cable with cross-linked polyethylene insulation have been improved, the useful life of having improved cable.
A kind of power cable with cross-linked polyethylene insulation of the present invention comprises cable core, is provided with packed layer in the gap of cable core, the outer wrapped armour of cable core, and the cable core outermost layer extrudes oversheath; Described cable core is to be 4mm by three cross sections
2Master core and a cross section are 1.5mm
2Auxiliary core is stranded to form, and the structure of its master core and auxiliary core is identical.
Further improve, described main and auxiliary index contour core is by conductor and be extruded in the outer non-linear insulating layer of conductor and constitute.
Further improve, described armour is combined by the first steel-tape armouring layer and the second steel-tape armouring layer again.
Beneficial effect of the present invention is:
Compared with prior art, the present invention adopts non-core insulating barrier, double armor structure, this non-linear insulating layer can improve high electric field the concentration problem inner and surface, thereby suppress formation and the development of crosslinked polyetylene insulated middle electric branch, improved aging phenomenon, improved job stability and the reliability of cross-linked polyethylene insulated cable, the double armor structure has also improved the shielding of cable, thereby has improved the useful life of cable.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of power cable with cross-linked polyethylene insulation of the present invention comprises cable core, is provided with packed layer 1 in the gap of cable core, the outer wrapped first copper strips armour 4 of cable core, the second copper strips armour 5, and the cable core outermost layer extrudes oversheath 6; Described cable core is to be 4mm by three cross sections
2Master core and a cross section are 1.5mm
2Auxiliary core is stranded to form, and the structure of its master core and auxiliary core is identical.Described main and auxiliary index contour core is made of conductor 1 and the non-linear insulating layer 2 that is extruded in the outer employing cross-linking polyethylene materials of conductor 1.
The concrete application approach of the present invention is a lot, and the above only is preferred implementation of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
