Abstract
The utility model discloses a novel YJV type cross-linked polyethylene insulated power cable. The novel YJV type cross-linked polyethylene insulated power cable includes conductors, a wrapping belt and an outer sheath; the three conductors are provided; each conductor is wrapped with a shielding layer, an insulating layer, an insulation shielding layer and a copper belt shielding layer sequentially; the three conductors are arranged in a manner that the three conductors form a structure shaped like a Chinese character "pin"; a filling layer is arranged among the conductors; the conductors are wrapped with a heat conduction layer; and the heat conduction layer is wrapped with the wrapping belt, a waterproof layer and the outer sheath sequentially. According to the novel YJV type cross-linked polyethylene insulated power cable of the utility model, the exteriors of the conductors are provided with the insulating layers and the shielding layers, and therefore, phase separation shielding can be realized, and electric fields can be shielded in the insulating layers, and power lines have no electric fields outside the radial full-shielding layers, and insulation breakdown field strength can be improved, and the service life of the cable can be prolonged.
Description
Technical field
The utility model relates to a kind of power cable, particularly relates to a kind of novel YJV type power cable with cross-linked polyethylene insulation.
Background technology
Power cable with cross-linked polyethylene insulation has remarkable heat-mechanical performance, excellent electric property and resistance to chemical corrosion, utilize chemical method and physical method to make the polyethylene of linear molecule structure be converted into the crosslinked polyethylene of space network, significantly improved poly hot mechanicalness, thereby kept excellent electric property, also had simple in structure, lightweight, laying advantages such as not being subject to drop restriction, is to be widely used at present urban distribution network, the novel cable of mine and factory.
But existing power cable with cross-linked polyethylene insulation, the insulating capacity of cable is poor, anti-breakdown field a little less than, heat dispersion and water resistance are poor, have reduced the useful life of cable.
Utility model content
The purpose of this utility model is to provide a kind of novel YJV type power cable with cross-linked polyethylene insulation, at conductor external insulation layer and screen, adopted phase-splitting shielding, by electric field shielding in insulating barrier, power line is all whole shielding layer radially, improved the disruptive field intensity of insulation, the useful life that has strengthened cable.
A novel YJV type power cable with cross-linked polyethylene insulation, comprises conductor, band and oversheath, and wherein, described conductor is three, and every conductor wraps up conductor shield, insulating barrier, insulation screen and copper strip shielding layer outward successively; Three described conductors are isosceles triangle to be arranged, and is provided with packed layer between conductor, and conductor is wrapped with heat-conducting layer, and described heat-conducting layer is enclosed with band, watertight composition and oversheath outward successively.
As preferably, described packed layer is provided with louvre.
As preferably, described louvre is arc.
As preferably, described louvre is three.
As preferably, described conductor is aluminium core or copper core conductor.
As preferably, described packed layer is Polyethylene Nanocomposites packed layer.
The beneficial effects of the utility model are:
The utility model is medium-pressure power cable, ceiling voltage 35KV.Conductor long-term work temperature is 90 ℃, has ageing-resistant performance, and mechanical performance, resistance to environment capacity are strong, insulation resistance is high, lightweight, and keeps good electric property, is applicable to transmission and distribution line and is used as adapted electric energy.The utility model adopts and presses the density that has strengthened product with milliken conductor, has reduced cross section, has improved electric conductivity, has prevented partial discharge, and has had waterproof action.Packed layer adopts Polyethylene Nanocomposites, and thermal conductivity is high and insulation property are good, also adds watertight composition in oversheath, has improved water resistance.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is further described:
As shown in Figure 1, the utility model comprises conductor 1, conductor screen 2, insulating barrier 3, insulation screen 4, copper strip shielding layer 5, heat-conducting layer 6, band 7, watertight composition 8 and oversheath 9.Three copper cores or aluminium core conductor are isosceles triangle and arrange, every conductor wraps up conductor shield 2, insulating barrier 3, insulation screen 4 and copper strip shielding layer 5 outward successively, gap-fill between three conductors has the packed layer 11 of being prepared by Polyethylene Nanocomposites, mica material or other thermal conductivity is high and insulation property are good material, on packed layer 11, louvre 10 can also be set, arranging of packed layer 11 and louvre 10 improved heat dispersion, extended the useful life of cable.Louvre 10 adopts the louvre of arc, and radiating effect is good.On each packed layer 11, can be provided with one or two louvre.In the present embodiment, packed layer 11 and louvre 10 are three.
The utility model has adopted phase-splitting shielding, three conductors arrange respectively insulating barrier and screen, by electric field shielding in insulating barrier, power line is all that radially whole shielding layer is outer without electric field, improved the disruptive field intensity of insulation, heat radiation of the present utility model and insulation effect are good, have improved the useful life of cable.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
