Abstract
The invention discloses a cross-linked polyethylene insulated power cable which comprises a cable core. A plurality of insulated wire cores are stranded to form the cable core, a filled layer is arranged at a gap of the cable core, a separation sleeve is extruded outside the cable core, an armor layer is weaved outside the separation sleeve, a warping tape is coated outside the steel wire armor layer, and an outer sheath is extruded on the outermost layer of the cable core. Each insulated wire core comprises a conductor, an internal shielding layer, an insulated layer, an external shielding layer and a copper tape, wherein the internal shielding layer, the insulated layer, the external shielding layer and the copper tape are respectively extruded outside the conductor. By the aid of a double-shielding structure, ageing is improved, working stability and reliability of the cross-linked polyethylene insulated cable are improved, the shielding performance of the cable is improved by the aid of a steel wire armor structure, 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 ageing resistance, job stability and good reliability, the power cable with cross-linked polyethylene insulation of long service life.
A kind of power cable with cross-linked polyethylene insulation of the present invention comprises cable core, and its cable core is by stranded the forming of some eradication edge cores; Gap at cable core is provided with packed layer, and cable core extrudes separation sleeve outward, and separation sleeve weaves armour outward, and band is covered in the outsourcing of wire armoring layer, and the cable core outermost layer extrudes oversheath; Described insulated wire cores is by conductor and is extruded in conductor outer internal shield, insulating barrier, outer shielding layer, copper strips successively and constitutes.
Further improve, described insulating barrier is made by cross-linking polyethylene materials.
Further improve, described armour is braided steel wire structure or steel band structure again.
Beneficial effect of the present invention is:
Compared with prior art, the structure that cable of the present invention adopts has been improved aging phenomenon, has improved job stability and the reliability of cross-linked polyethylene insulated cable, double shield, wire armoring structure have also improved the shielding of cable, thereby have 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, and its cable core is by stranded the forming of some eradication edge cores; Be provided with packed layer 6 in the gap of cable core, cable core extrudes bag separation sleeve 7 outward, separation sleeve 7 outer braiding armours 8, and band 9 is covered in 8 outsourcing of wire armoring layer, and the cable core outermost layer extrudes oversheath 10; Described insulated wire cores is by conductor 1 and is extruded in conductor 1 outer internal shield 2, insulating barrier 3, outer shielding layer 4, copper strips 5 successively and constitutes.
Insulating barrier described above 3 is made by cross-linking polyethylene materials; Described armour 8 is braided steel wire structure or steel band structure.
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.
