Abstract
The utility model discloses a fire-resistant water-proof environmental protection cable, comprising cable cores, a radial water-proof buffer layer wrapping around the cable cores, an oxygen insulation sleeve, a protection layer and an outer protection layer coating the outer surface of the radial water-proof buffer layer in turn; wherein a filler is filled between each cable core and the radial water-proof buffer layer; each cable comprises: a conductor, a fire-resistant layer and an insulation layer from inside to outside. The advantages of the cable are that: the cable effectively proofs the water along the vertical and radial direction and the fire-resistant layer and the steel-plastic composite synthetic protection layer are arranged to effective resist the fire, even though in the more severe environment, the enough safety is also ensured and all the material uses the halogen-free material and harmful gas such as hydrogen halide is not generated to prevent secondary damage.
Description
Technical field
The utility model relates to a kind of power cable, is a kind of fire-resistant waterproof environment-friendly cable specifically.
Background technology
Automatic sprinkler system is the most effectively first-aid extinguishing facility of generally acknowledging in the world today, is most widely used general, automatic fire extinguishing system that consumption is maximum.Domestic and international application facts have proved: this system has safe and reliable, economical and practical, fire extinguishing success rate advantages of higher.The external history in existing more than 100 year of automatic sprinkler system of using, automatic sprinkler system is not only applied in skyscraper, public building, industrial premises and warehouse, and developed country has begun to install and use in residential housing.In the Building Fire Protection design, apply automatic sprinkler system, obtained huge social and economic benefit.Abide by country about the policy of capital construction and the fire-fighting work policy of " put prevention first, combine prevention with fire fighting ", make automatic sprinkler system application more and more widely according to the requirement of national standard fire-fighting acceptance specification.
The integrality of at present external fire-retardant, fire-resisting cable circuit and taked more harsh experimental condition in order to guarantee, shake combustion experiment by the BS6387 requirement by horizontal firing experiment, the experiment of water spray and mechanical shock, but domestic fire-retardant, fire-resisting cable also will not spray and vibration condition is brought in the test and gone, and also should give consideration in order to ensure the circuit integrality.The technological level and the material horizontal of just at present generally fire-retardant, fire-resisting cable are difficult to reach the BS6387 requirement, also are difficult to guarantee the integrality of circuit.
The cable that generally is used in places such as skyscraper and intelligent building etc. is the environment-friendly type fire-resisting cable, even if can reach fire resistance, do not produce pernicious gases such as hydrogen halides, avoided the requirement of secondary injury aspect, can not guarantee the circuit integrality under water spray situation.
The utility model content
Goal of the invention: the purpose of this utility model is to overcome and has deficiency fire-retardant, the fire-resisting cable performance now, and a kind of fire-resistant waterproof environment-friendly cable that can effectively guarantee the integrality of circuit is provided.
Technical scheme: in order to solve the problems of the technologies described above, a kind of fire-resistant waterproof environment-friendly cable described in the utility model, comprise a plurality of cable cores, water-blocking buffer layer radially, described radially water-blocking buffer layer is wrapped in the outside of described a plurality of cable cores, is coated with oxygen barrier cover, overcoat, outer jacket successively in the outside of described radially water-blocking buffer layer; At each cable core and radially be provided with filler between the water-blocking buffer layer; Described cable core comprises conductor, flame retardant coating, insulating barrier from inside to outside successively.
In described conductor, be filled with the intumescent material water-proof material.Guaranteed vertical block-water performance of cable conductor.
Described overcoat is that steel is moulded compound integrated protection layer.
Described overcoat clearance-type is put up wrapped outside at described oxygen barrier cover; Can effectively prevent fires, and have under the flame situation, plastic cement meeting fusion is in aggregates, also can play resistance effect.
Described flame retardant coating is two-sided mica tape; Make each phase line be isolated from each other and play insulating effect, can guarantee electric property and the serviceability of cable under the flame situation.
Described insulating barrier is a vinyl polymer, and filler is fire-retardant, waterproof material.Radially water-blocking buffer layer is a waterstop; Can play resistance effect when water intrusion is arranged, can also play the buffering buffer action that external heat is imported in addition, the oxygen barrier cover is high oxygen index Halogen material oxygen barrier cover, and outer jacket is high oxygen index Halogen material outer jacket.
Oxygen barrier cover, outer jacket adopt high oxygen index Halogen material in the utility model, can not produce pernicious gases such as hydrogen halides, have avoided the secondary injury.
Beneficial effect: compared with prior art, the utility model has the advantages that the integrality that can effectively guarantee circuit.Especially spray equipment has all been installed in places such as skyscraper and intelligent building etc., can automatic spray when it the condition of a fire occurs, may occur also vibrating etc. that general unicity under the situation is fire-resistant, waterproof, environment-friendly cable performance deficiency perfect.
