Abstract
The present invention discloses a shielding insulating power cable. The shielding insulating cable comprises a cable body, and the cable body comprises conductors, an insulating layer, a shielding layer and an outer sheath. The cross-section of the cable body is a circular structure, the plurality of conductors are arranged inside the cable body, and the protection sleeves wrap the conductors. The conductors and the protection sleeves form the cable cores jointly, a plurality of cable cores are arranged inside the cable body, and the insulating layer is extruded on the outsides of the cable cores. A filling layer is arranged in the gap part between the insulating layer and the cable cores, and the shielding layer is extruded on the outside of the insulating layer. An armored layer and an inner sheath are extruded on the shielding layer orderly from inside to outside, and the outer sheath is extruded on the outside of the inner sheath tightly. The shielding insulating cable has the advantages of reasonable structure design, good use effect, long service life, etc.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of insulated shield cable.
Background technology
At present, along with the development of science and technology, no matter be industry or the daily life of the mankind, all towards electrified future development, cable is then in industry and power domain, its status is also raising gradually, the existing construction of cable comprises many conductors, be coated on the insulating barrier outside each conductor, several part such as braid and sheath, but the anti-external disturbance performance of the cable of this structure and envelope eapsulotomy poor, easily cause distorted signals, therefore Signal transmissions is very unstable, the image of transmission is also unintelligible, and existing cable humidity resistance is not fine, be easy to oxidized, if used for a long time, be easy to cable inside is gone wrong, cause the short circuit of system, thus bring a lot of inconvenience to enterprise.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of insulated shield cable.
The present invention takes following technical scheme to realize: a kind of shielding insulation power cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body cross section is circular configuration; Described cable body inside is provided with many conductors; Described conductor outer wrapping one deck protective sleeve; Described conductor and protective sleeve form cable core jointly; Described cable body inside is provided with many cable cores; A layer insulating is extruded outside described cable core; Between described insulating barrier and cable core, gap portion is provided with packed layer; One deck screen is extruded outside described insulating barrier; Described screen extrudes armour and inner sheath from inside to outside successively; Described inner sheath closely extrudes one deck oversheath outward.
Above-mentioned a kind of insulated shield cable, described conductor forms by multiply tinned copper wire is stranded.
Above-mentioned a kind of insulated shield cable, described armour is the composite bed combined by glass fiber tape and polyester belt.
Above-mentioned a kind of insulated shield cable, described inner sheath and oversheath are made up of polythene material.
The present invention has following beneficial effect in sum: this cable has the advantages such as the good and long service life of reasonable in design, result of use, and described conductor is that tin-coated copper tow is stranded forms, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor structure is easy to processing, making length is unrestricted, there is during use certain flexibility and bendability, facilitate the laying of workpeople, substantially increase the intensity of cable, effectively extend the useful life of cable body.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, cable body; 2, conductor; 3, protective sleeve; 4, packed layer; 5, insulating barrier; 6, screen; 7, armour; 8, inner sheath; 9, oversheath.
Embodiment
As shown in Figure 1, a kind of shielding insulation power cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 5, screen 6 and oversheath 9, and described cable body 1 cross section is circular configuration; Described cable body 1 inside is provided with many conductors 2; Described conductor 2 outer wrapping one deck protective sleeve 3; Described conductor 2 and protective sleeve 3 form cable core jointly; Described cable body 1 inside is provided with many cable cores; A layer insulating 5 is extruded outside described cable core; Between described insulating barrier 5 and cable core, gap portion is provided with packed layer 4; One deck screen 6 is extruded outside described insulating barrier 5; Described screen 6 extrudes armour 7 and inner sheath 8 from inside to outside successively; Described inner sheath 8 is outer closely extrudes one deck oversheath 9.
Described conductor 2 forms for tin-coated copper tow is stranded, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor 2 structure is easy to processing, making length is unrestricted, has certain flexibility and bendability during use, facilitates the laying of workpeople, substantially increase the intensity of cable, effectively extend the useful life of cable body 1; Described packed layer 4 can effectively prevent ambient pressure to the harmful effect of conductor 2, also can realize the integral slipping of conductor 2 in BENDING PROCESS, ensure that stability and the bending property of cable; The screen 6 extruded outside described insulating barrier 5 can improve the interference free performance of cable greatly, makes it easily by external interference, thus can not make cable work better effects if, also improves operating efficiency.
The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
