Technical field
The present invention relates to field of cables, particularly relate to a kind of fire resistant flexible high-temperature insulation cable.
Background technology
At present, along with the development of science and technology, the fields such as industry are also at rapid advances, what bring is the increase of cable consumption thereupon, cable normally has several or several groups of wires often to organize the cable of at least two stranded similar ropes, often organize mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the cover layer of high-insulation, the kind of cable has a lot, the environment for use that can be applied in fields different in a lot of field is different, therefore different requirements is also had to cable, existing cable because of its structural design unreasonable, can not satisfy the demand, general cable is when high temperature or breaking out of fire, be easy to the situation occurring burning, it can discharge the gas be harmful to environment and human body in combustion, and the damage of cable skin, electrical fire can be caused, bring larger loss.
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 fire resistant flexible high-temperature insulation cable.
The present invention takes following technical scheme to realize: a kind of fire resistant flexible high-temperature insulation 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; And be fixedly connected with by rubber skeleton between described conductor; A layer insulating is extruded outside described conductor; Described insulating barrier inside is provided with many gum fillers; Gap portion between described insulating barrier and conductor is provided with packed layer; One deck screen is extruded outside described insulating barrier; Layer of metal extruded layer is extruded outside described screen; Layer of glass fiber polyester belt is extruded outside described extruding metal layer; One deck oversheath is extruded outside described glass polyester belt.
Above-mentioned a kind of fire resistant flexible high-temperature insulation cable, described conductor adopts that tinned copper wire is stranded to be formed.
Above-mentioned a kind of fire resistant flexible high-temperature insulation cable, described extruding metal layer is galvanized steel strip material.
Above-mentioned a kind of fire resistant flexible high-temperature insulation cable, described insulating barrier, Thickness Ratio between screen and metal resistance to compression layer are 1:1:1.
Above-mentioned a kind of fire resistant flexible high-temperature insulation cable, described glass polyester belt is the composite bed combined by glass fibre belt and polyester belt.
Above-mentioned a kind of fire resistant flexible high-temperature insulation cable, described oversheath adopts the corrosion-resistant polyolefine material of low-smoke non-halogen flame-retardant to make.
The present invention has following beneficial effect in sum: this cable has the advantages such as strong, the high temperature resistant and long service life of conductivity, described extruding metal layer adopts galvanized steel strip material to make, described galvanized steel strip effectively can improve the stretch-proof performance of cable, the performance making cable bear pressure improves greatly, extends its useful life.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, cable body; 2, conductor; 3, packed layer; 4, rubber skeleton; 5, insulating barrier; 6, screen; 7, metal resistance to compression layer; 8, glass polyester belt; 9, oversheath; 10, gum filler.
Embodiment
As shown in Figure 1, a kind of fire resistant flexible high-temperature insulation 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; And be fixedly connected with by rubber skeleton 4 between described conductor 2; A layer insulating 5 is extruded outside described conductor 2; Described insulating barrier 5 inside is provided with many gum fillers 10; Gap portion between described insulating barrier 5 and conductor 2 is provided with packed layer 3; One deck screen 6 is extruded outside described insulating barrier 5; Layer of metal extruded layer 7 is extruded outside described screen 6; Layer of glass fiber polyester belt 8 is extruded outside described extruding metal layer 7; One deck oversheath 9 is extruded outside described glass polyester belt 8.
Described conductor adopts that tinned copper wire is stranded to be formed, thus substantially increase conductor 2 electric conductivity, make its work more stable; Many described conductors 2 form cable core, are fixedly connected with between described cable core by rubber skeleton 4, thus make the structure of cable body 1 inside compacter, improve its service behaviour; Extrude a layer insulating 5 outside described cable core, thus the insulation property of cable body 1 can be improved, the ampacity of cable is improved greatly; The packed layer 3 arranged between described insulating barrier 5 and conductor 2 can reduce the heat absorption capacity coefficient of material, presses structure and reduces construction of cable part thermal resistivity, cable dissipate heat effect is increased, effectively can prevent the overheated burning of cable by densification; The many gum fillers 10 that described insulating barrier 5 inside is arranged at high temperature can play the effect of cooling to cable, thus protection cable can not be damaged; The outer screen 6 arranged of described insulating barrier 5 can avoid cable body 1 inside to produce insulation breakdown phenomenon, reduces outside electromagnetic interference to the impact of electric field simultaneously, improves the shielding properties of cable body 1; The outer extruding metal layer 7 arranged of described screen 6 is galvanized steel strip material, effectively can strengthen the bulk strength of cable, make cable can bear larger load and External Force Acting, and effectively can prevent the animal bites bad cable of mouse and so on, for cable provides better protection; Described glass polyester belt 8 is the composite beds combined by glass fibre belt and polyester belt, thus makes cable have high temperature resistant and cold-resistant performance, and under rugged environment, electric property also can be kept to stablize, and conveniently uses for a long time; Described oversheath 9 adopts the corrosion-resistant polyolefine material of low-smoke non-halogen flame-retardant to make, higher temperature can be born, 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 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.
