Abstract
The utility model discloses a crosslinking polyethylene-insulated power cable. The crosslinking polyethylene-insulated power cable comprises a cable core; the gap of the cable core is provided with a filling layer; the cable core is wrapped by a first steel band armor layer and a second steel band armor layer; the outer most layer of the cable core is wrapped by an oversheath in an extruding manner; the cable core is formed by twisting three main wire cores each with a cross section of 4 mm<2> and an auxiliary wire core with a cross section of 1.5 mm<2>; the main wire cores and the auxiliary wire core are of the same structure; and the main wire cores and the auxiliary wire core are composed of conductors and non-linear insulating layers wrapped outside the conductors. The crosslinking polyethylene-insulated power cable improves the aging phenomenon of a crosslinking polyethylene-insulated layer, enhances the working stability and reliability of the crosslinking polyethylene-insulated power cable, and prolongs the service life of the cable.
Description
Technical field
The utility model relates to the electric wire field, specifically refers 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 large, can high drop or the advantages such as vertical run, installation and maintenance aspect, it applies very extensive in high pressure and extra-high-tension cable field.In the practical application of power cable with cross-linked polyethylene insulation, because the reason such as aging is easy to cause the deteriorated of crosslinked polyetylene insulated layer and destroys.By series of improving measures, still still can't eliminate the formation and development of electric branch aging phenomenon in crosslinked polyetylene insulated layer fully in prior art; In carrying out high pressure and superhigh pressure transmitting procedure, due to the decline of insulation property, exist the potential safety hazard of cable breakdown.Therefore, how the structure of power cable with cross-linked polyethylene insulation in 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.
The utility model content
Technical problem to be solved in the utility model is to provide 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 described in the utility model, comprise cable core, in the gap of cable core, is provided with packed layer, 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 be formed, 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 form.
Further improve, described armour is combined by the first steel-tape armouring layer and the second steel-tape armouring layer again.
The beneficial effects of the utility model are:
Compared with prior art, the utility model adopts non-core insulating barrier, double armor structure, this non-linear insulating layer can improve high electric field 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of power cable with cross-linked polyethylene insulation described in the utility model, comprise cable core, in the gap of cable core, is provided with packed layer 1, outer wrapped the 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 be formed, and the structure of its master core and auxiliary core is identical.Described main and auxiliary index contour core consists 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 utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
