Description
Technical field
The utility model relates to field of cables, particularly relates to the industrial insulated cable of a kind of fire-proof high-temperature resistant.
Background technology
At present, cable is widely used in electric power, the fields such as communications, along with the development of science and technology, cable all has a wide range of applications in every field, but existing used in the industry cable, because its structural design is unreasonable, the needs of present people can not be met, some cables are shorter for useful life, and not there is good stretch-proof performance, when a fire, cable can not bear high temperature, cause the situation of cable bad, and when cable fire, common cable is because of material problem, a large amount of harmful gas can be produced, thus exacerbate the destruction of fire to life and property.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the industrial insulated cable of a kind of fire-proof high-temperature resistant.
The utility model is taked following technical scheme to realize: the industrial insulated cable of a kind of fire-proof high-temperature resistant, and it comprises cable body; Described cable body comprises conductor, screen, insulating barrier and oversheath, and described cable body inside is provided with many conductors; The cross section of described cable body is circular configuration; Three described conductors form cable core; A layer insulating is extruded outside described conductor; Gap portion between described insulating barrier and conductor is provided with packed layer; And the gap portion between described insulating barrier and conductor is provided with many aluminium alloy flexible pipes; One deck screen is extruded outside described insulating barrier; Described screen is extruded with armour, fireprotection layer and inner sheath from inside to outside successively; Described inner sheath closely extrudes one deck oversheath outward.
The above-mentioned industrial insulated cable of a kind of fire-proof high-temperature resistant, described insulating barrier adopts second third insulation compound to make.
The above-mentioned industrial insulated cable of a kind of fire-proof high-temperature resistant, described insulating barrier, Thickness Ratio between screen and armour are 1:1:1.
The above-mentioned industrial insulated cable of a kind of fire-proof high-temperature resistant, described armour is wound around by nonmagnetic metal band or wire to make.
The above-mentioned industrial insulated cable of a kind of fire-proof high-temperature resistant, described fireprotection layer is mixed by fire-retardant nylon and the non-twist coarse sand of middle alkali.
The above-mentioned industrial insulated cable of a kind of fire-proof high-temperature resistant, described oversheath and inner sheath adopt any one material in smoke halogen-free flame-proof plastic for low polyvinyl chloride or corrosion-inhibiting coating to be made.
The utility model has following beneficial effect in sum: this cable has good shielding properties, resist bending performance and the performance such as high temperature resistant; also there is high pressure resistant and diamagnetic jamming performance simultaneously; described armour is wound around by nonmagnetic metal band or wire to make; the problem of eddy current can be produced when can eliminate magnetic material armouring; the effect of more protection can also be played to the construction of cable simultaneously; effectively reduce the damage that cable is subject to when impacting, extend the useful life of body.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram.
Wherein: 1, cable body; 2, conductor; 3, aluminium alloy flexible pipe; 4, packed layer; 5, insulating barrier; 6, screen; 7, armour; 8, fireprotection layer; 9, inner sheath; 10, oversheath.
Embodiment
As shown in Figure 1, the industrial insulated cable of a kind of fire-proof high-temperature resistant, it comprises cable body 1; Described cable body 1 comprises conductor 2, screen 6, insulating barrier 5 and oversheath 10, and described cable body 1 inside is provided with many conductors 2; The cross section of described cable body 1 is circular configuration; Three described conductors 2 form cable core; A layer insulating 5 is extruded outside described conductor 2; Gap portion between described insulating barrier 5 and conductor 2 is provided with packed layer 4; And the gap portion between described insulating barrier 5 and conductor 2 is provided with many aluminium alloy flexible pipes 3; One deck screen 6 is extruded outside described insulating barrier 5; Described screen 6 is extruded with armour 7, fireprotection layer 8 and inner sheath 9 from inside to outside successively; Described inner sheath 8 is outer closely extrudes one deck oversheath 9.
The conductor 2 that described cable body 1 inside is arranged effectively can improve the electric conductivity of cable, also makes cable more stable by the process of conductor 2 signal transmission; And three described conductors 2 form the service behaviour that cable core can improve conductor 2, the packed layer 4 that between described conductor 2 and insulating barrier 5, gap portion is arranged makes cable internal structure compacter, extends the useful life of cable body 1; Described aluminium alloy flexible pipe 3 effectively can improve the elasticity of cable, and effective buffering cable is subject to stronger impulsive force; Described insulating barrier 5 adopts ethylene-propylene rubber compound to make, and improves the resistance to elevated temperatures of cable body 1, and the ampacity of cable is improved greatly; Described screen 6 can avoid insulation breakdown phenomenon, reduces outside electromagnetic interference to the impact of electric field simultaneously; Described armour 7 is wound around by nonmagnetic metal band or wire to make, the problem of eddy current can be produced when can eliminate magnetic material armouring, the effect of more protection can also be played to the construction of cable simultaneously, effectively reduce the damage that cable is subject to when impacting, extend the useful life of cable body 1; Described fireprotection layer 8 is mixed by fire-retardant nylon and the non-twist coarse sand of middle alkali, and can improve the resistance to elevated temperatures of cable body 1, making it work under the high temperature conditions can not be affected, and substantially increases its result of use; Described inner sheath 9 and oversheath 10 adopt any one material in smoke halogen-free flame-proof plastic for low polyvinyl chloride or corrosion-inhibiting coating to be made, thus make cable can bear higher temperature, and harmful Substances Pollution environment can not be produced in hot environment, thus make its environmental-protecting performance more excellent, meet present the advocated environmental protection concept of people.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
