Abstract
The utility model relates to a high-flame-retardant fire-resistant cable which comprises a plurality of multi-core conductors. Each multi-core conductor is formed by twisting multiple single-core conductors, and the outer side of each multi-core conductor is sequentially wrapped with a first wrapping layer, a metal sleeve and a color separation layer from inside to outside; the multi-core conductors are twisted, and filling layers are arranged among the multi-core conductors; the outer sides of the twisted multi-core conductors are sequentially provided with a first oxygen isolation layer, a second wrapping layer, a second oxygen isolation layer, a third wrapping layer and an outer sheath from inside to outside, and multiple steel wires are arranged in the second oxygen isolation layer; the first wrapping layers are inorganic mineral insulating claddings, the second wrapping layer is a non-woven cloth cladding, the third wrapping layer is a non-woven cloth cladding, and the metal sleeves are aluminum drawn tubes. The high-flame-retardant fire-resistant cable has the advantages that the cable meets the requirements for electric and mechanical performance, and is good in fireproof effect, free of toxins, safe and reliable to use and high in practicality.
Description
Technical field
The utility model relates to a kind of high flame retardant fire-resisting cable.
Background technology
The decoration that many modernizations obtain the important public places such as office building, hotel, market, subway, railway station, residential building is more and more luxurious, the combustible using is more and more, for preventing fire, the circuit of finishing must adopt the cable that fire protecting performance is good, to reduce fire damage.The sheath that fireproof 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 fireproof electric 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 currently available technology 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, comprises some multi-core conductors, and described multi-core conductor is by stranded the forming of some single core conductors, and the outside of described multi-core conductor is enclosed with lapping layer one, metal sleeve and dichroic layer from the inside to the outside successively; Described some multi-core conductors are mutually stranded, between described some multi-core conductors, are provided with packed layer; Described multi-core conductor outside after stranded is provided with oxygen barrier layer one, lapping layer two, oxygen barrier layer two, lapping layer three and oversheath from the inside to the outside successively, in described oxygen barrier layer two, is provided with some steel wires.
Further, the material of described lapping layer one, filling bed, oxygen barrier layer one and oxygen barrier layer two is inorganic mineral.
Further, the material of described dichroic layer and oversheath is polyolefin.
