Abstract
The invention discloses a moisture-proof high-voltage-withstanding power cable comprising a cable body which comprises conductors, an insulating layer, a shielding layer and an external sheath. The internal part of the cable body is provided with multiple conductors which are externally provided with a layer of glass fiber pipe respectively. A cable core is formed by the glass fiber pipes and the conductors together. The cable core is externally extruded by a layer of insulating layer. Fillers are arranged in the gap part between the insulating layer and the cable core. The insulating layer is closely extruded by a layer of shielding layer externally. The shielding layer is extruded by a reinforcing braiding layer and an anticorrosion layer from inside to outside in turn. The anticorrosion layer is closely extruded by a layer of external sheath externally. The cable has advantages of being reasonable in structural design, water-resistant and moisture-proof and long in the service life.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of damp-proof anti-high voltage power cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as in aviation, the cable used in the fields such as electric power, high all especially to the requirement of the high pressure resistant and diamagnetic jamming performance aspect of cable, but now used on the market cable is because its structural design is unreasonable or the problem such as material, effective protective effect can not be played, when cable works in a humidity environment, moisture is easy to invade cable inside through cable cover(ing), conductor is not only made to be corroded, and easily cause the short circuit of system, very large trouble is brought 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 damp-proof anti-high voltage power cable.
The present invention takes following technical scheme to realize: a kind of damp-proof anti-high voltage power cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with many conductors; Layer of glass pipe is set outside described conductor; Described fiberglass pipe and conductor form cable core jointly; Described cable core closely extrudes a layer insulating outward; Between described insulating barrier and cable core, gap portion is provided with filler; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with reinforcing braid and corrosion-resistant coating from inside to outside successively; Described corrosion-resistant coating closely extrudes one deck oversheath outward.
Above-mentioned a kind of damp-proof anti-high voltage power cable, described conductor forms by multiply tinned copper wire is stranded.
Above-mentioned a kind of damp-proof anti-high voltage power cable, described filler is that asbestos or glass material are made.
Above-mentioned a kind of damp-proof anti-high voltage power cable, described reinforcing braid is woven by stainless steel wire to form.
Above-mentioned a kind of damp-proof anti-high voltage power cable, described oversheath adopts butyronitrile pvc material to make.
The present invention has following beneficial effect in sum: this cable has the advantages such as reasonable in design, water-blocking moistureproof and long service life, described oversheath is that butyronitrile pvc material is made, cable is made to have the ability of good resistance to aromatic solvent, chemical-resistant resistance and solvent corrosion, and there is the performances such as lower shielding rejection coefficient is little, thus substantially increase the Corrosion Protection of cable.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, cable body; 2, conductor; 3, fiberglass pipe; 4, filler; 5, insulating barrier; 6, screen; 7, reinforcing braid; 8, corrosion-resistant coating; 9, oversheath.
Embodiment
As shown in Figure 1, a kind of damp-proof anti-high voltage 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 inside is provided with many conductors 2; Outside described conductor 2, layer of glass pipe 3 is set; Described fiberglass pipe 3 and conductor 2 form cable core jointly; Described cable core closely extrudes a layer insulating 5 outward; Between described insulating barrier 5 and cable core, gap portion is provided with filler 4; Described insulating barrier 5 is outer closely extrudes one deck screen 6; Described screen 6 is extruded with reinforcing braid 7 and corrosion-resistant coating 8 from inside to outside successively; Described corrosion-resistant coating 8 is outer closely extrudes one deck oversheath 9.
Described conductor 2 forms by multiply tinned copper wire is stranded, thus have good corrosion resistance, and stable work in work, can larger electric current be carried; Described insulating barrier 5 effectively can improve the insulation property of cable, makes it use convenient; The screen 6 extruded outside described insulating barrier 5 effectively raises the shielding properties of cable body 1, avoids the interference of signal, makes it use more stable; Described oversheath 9 is made for butyronitrile pvc material, makes cable have the ability of good resistance to aromatic solvent, chemical-resistant resistance and solvent corrosion, and has the performances such as lower shielding rejection coefficient is little, thus substantially increase the Corrosion Protection of cable.
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.
