Description

A kind of high flame retardant fire-resisting cable
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of high flame retardant fire-resisting cable.
Background technology
Along with the development of the modernization of industry and the reinforcement of people's fire-fighting consciousness, after " Fire Prevention Law " of particularly promulgating in China comes into force, all trades and professions are also further improved the attention degree of electric wire fire resistance, many modernizations obtain the important public places such as office building, hotel, market, subway, railway station, residential building, decorate more and more luxurious, the combustible using is more and more, and this just requires circuit to adopt the good cable of fire resistance, to reduce fire damage.The sheath that fire-resisting cable adopts polyvinyl chloride to add fire retardant manufacture more at present carries out fire-retardant, but this method significantly rises cable cost; In addition, owing to containing a large amount of halogens in fire retardant, electric wire will be emitted a large amount of poison gas, acid mist and flue gas in the time of burning, these combustion products not only threat to life are complete, contaminated environment, also can cause the heavy corrosion of equipment and building, withdraw and rescue property to fire extinguishing, fire-extinguishing and lifesaving and personnel and cause very large obstacle.Therefore promoting people to research and develop the clean and environment-friendly power cable of low cigarette, Halogen, low toxicity, is the trend of current fire-resistant wire and cable development.
Utility model content
The purpose of this utility model is to provide a kind of high flame retardant fire-resisting cable, to overcome current existing cable above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of high flame retardant fire-resisting cable, comprise multiple cores, described core comprises some stranded conductor, inorganic mineral insulating barrier, aluminium cover, crosslinked polyetylene insulated layers of pressing, described some stranded conductor outsides of pressing are provided with inorganic mineral insulating barrier, inorganic mineral insulating barrier outside is provided with aluminium cover, and aluminium cover outside is provided with crosslinked polyetylene insulated layer.Described multiple cores are provided with oxygen barrier layer outward, filled composite carbon fiber between described oxygen barrier layer and multiple core and between multiple core, described oxygen barrier layer (6) is made up of soft organic fire prevention material, described oxygen barrier layer outside is provided with polyester belt wrapping layer, and polyester belt wrapping layer outside is provided with polyolefin and extrudes layer.
Further, described multiple cores are 2 to 5.
Further, described conductor is copper cash.
The beneficial effects of the utility model are: this cable had both met the requirement of electric, the mechanical performance of cable, had again good fire protecting performance, safe and reliable, practical.
Brief description of the drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of a kind of high flame retardant fire-resisting cable described in the utility model embodiment.
In figure:
1, conductor; 2, inorganic mineral insulating barrier; 3, aluminium cover; 4, crosslinked polyetylene insulated layer; 5, carbon fiber reinforce plastic; 6, oxygen barrier layer; 7, polyester belt wrapping layer; 8, polyolefin extrudes layer; 9, core.
Embodiment
As shown in Figure 1, a kind of high flame retardant fire-resisting cable described in the utility model embodiment, comprises multiple cores 9, and described core 9 comprises some stranded conductor 1, inorganic mineral insulating barrier 2, aluminium cover 3, crosslinked polyetylene insulated layers 4 of pressing, described some stranded conductors 1 that presses, preferably copper cash.Many conductor 1 outsides are provided with inorganic mineral insulating barrier 2, and this insulating barrier is lapped insulation.Inorganic mineral insulating barrier 2 outsides are provided with aluminium cover 3, and aluminium overlaps 3 outsides and is provided with crosslinked polyetylene insulated layer 4.
Stranded 4 cores 9, when stranded, fill with carbon fiber reinforce plastic 5 centre.By filling process at carbon fiber reinforce plastic 5 and the soft organic fire prevention material of the additional one deck of Duo Gen core 9 as oxygen barrier layer 6.Tighten at oxygen barrier layer 6 external application one deck polyester belts 7, be provided with polyolefin in polyester belt 7 outsides and extrude layer 8.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
