Description
Technical field
The utility model relates to electric wire field, and particularly a kind of energy-conserving and environment-protective inorganic mineral compound surpasses flexible fire-proof cable.
Background technology
Skyscraper of today has become the important place of a lot of citizen's routine work, life, but skyscraper fire extinguishing but becomes an international fire-fighting difficult problem, skyscraper is once catch fire after all, building can be closed by dense smoke very soon, formed " stack effect ", the flue gas of more than 800 degrees Celsius runs into any article all can make it burn, and simultaneously strong smog and the fierce burning that brings thereof, will have a strong impact on the resident's escape being confined in floor.
The equipment such as the fire protection equipment in common floor, elevator, illumination guides resident's escape to save oneself when being all used to fire, but big fire can cause electric wire, cable burns, and after stand-by power supply consumes, these equipment are by a standstill; And electric wire, ignition of cable, not only can accelerate spreading of the intensity of a fire, also by a large amount of for release poison gas, toxic smoke; If electric wire is exposed charged, the resident escaped in fire also has Danger Electric shock risk.Series of problems not only affects resident's escape and necessary salvage operation, also can delay the rescue period of fire fighter's preciousness.
According to statistics, the frequency of electrical fire and the loss that causes all belong to first of all kinds of fire.According to analysis, that is wherein caused by circuit accounts for the over half of electrical fire, even if so reasonably select cable to be avoid electrical fire or breaking out of fire also can the Reliable guarantee fire-fighting equipment continuity of powering, and then puts out a fire as early as possible, the important step of reducing the loss.
Traditional in the market cable (comprising fire-retardant, low-smoke low-halogen, low smoke and zero halogen and its corresponding fire-resisting cable) catching fire, burnt or overload insulation is for a long time impaired time smog and pernicious gas all can exist, all cannot meet fire protection requirement.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, and providing is that a kind of production cost is low, and good bending property, fire protecting performance are good, and when manufacturing, the inorganic mineral compound of energy-conserving and environment-protective surpasses flexible fire-proof cable simultaneously.
The utility model discloses a kind of energy-conserving and environment-protective inorganic mineral compound and surpass flexible fire-proof cable, comprise cable core, described cable core is made up of single or many inorganic mineral insulation cores; Glass fiber rope is filled in the gap of cable core; At the outer wrapped two-layer LSOH anti-flaming band of cable core, outside LSOH anti-flaming band, be provided with the aluminium alloy fireproof metal protective layer that one deck adopts interlocking structure to form; One deck halogen-free and low-smoke flame-retardant polyolefin oversheath is extruded outward again at aluminium alloy fireproof metal protective layer.
In the utility model, preferably, when described cable core is multicore, it is by the large inorganic mineral insulation core of four cross sections that structure is identical and the little inorganic mineral insulation core of cross section is stranded side by side forms.
In the utility model, preferably, described inorganic mineral insulation core is made up of the inorganic mineral insulation band of center conductor, wrapped layer 2-4 outside conductor and the halogen-free and low-smoke flame-retardant polyolefin insulating barrier be extruded in outside inorganic mineral insulation band.
In the utility model, preferably, described conductor forms by high connductivity creep resistant aluminium alloy single wire type line is stranded.
In the utility model, preferably, described inorganic mineral insulation band is mica tape or ceramic fireproof silicon rubber composite band.After adopting technique scheme, the utility model has following beneficial effect:
(1) conductor adopts high connductivity creep resistant aluminium alloy, and cost is compared with copper can reduce by 35 ~ 42%, can save copper resource again simultaneously.
(2) conductor adopts molded line lay configuration, compares circle and presses structure and can make insulation and sheath material cost savings 10% ~ 15%.
(3) the aluminium alloy fireproof metal protective layer adopting interlocking structure to produce, can save 50% ~ 70% of sheath cost than traditional copper sheath.
(4) sheath material is environmental protection low-smoke low-halogen or low smoke and zero halogen protective cover material, and when breaking out of fire, cable LSZH, to human body fanout free region, is conducive to people's escape.
