The utility model discloses a crowded package of interior sandwich layer surface has pottery low smoke and zero halogen polyolefin insulation layer, need not around the package mica tape, the utility model discloses have the very good thermal -insulated fire effect that separates, the environmental protection is pollution -free, can wide application in the very high place of public fire control, fire protection requirement.
Description
Technical field
The utility model relates to cable, particularly a kind of ceramic low-smoke halogen-free polyolefin insulation fireproof environmental cable.
Background technology
At present, the fire-resistant cable of occuping market is the low smoke halogen-free fire retardant fire resistant cable of Mica tape substantially.Even adopt the flame-retardant insulating material of low smoke and zero halogen; also can only delay flame-retardant insulating material and be burnt till the time of powder; if continue to be burnt; just gradually powder and come off; lose protective effect; electric wire is easy to breakdown and causes short circuit, thus is difficult to ensure communication, electric power in case of fire safe and smooth.And mica tape can produce dust pollution in cable production process, chafe and respiratory tract.
Utility model content
The purpose of this utility model provides a kind of fire prevention, nontoxic, environmental protection, fail safe high, still can maintain the security personnel of energising, ceramic low smoke and zero halogen fireproof environmental cable that the emergency power supply of disaster relief power supply and fire extinguishing, warning, illumination, communication etc. uses under being suitable for fire condition.
To achieve these goals, the utility model have employed following technical scheme:
A kind of ceramic low-smoke halogen-free polyolefin insulation fireproof environmental cable, be provided with cable core layer, fire-resistant composite band and restrictive coating from the inside to the outside successively, described cable core layer comprises multiple cable core, each described cable core comprises inner sandwich layer, each described inner sandwich layer outer surface is extruded with insulating barrier, be filled with fire-resistant fire prevention gasket for packing between multiple described cable core, described fire-resistant fire prevention gasket for packing is the fire-resistant fire prevention gasket for packing of ceramic, and described insulating barrier is ceramic low-smoke halogen-free polyolefin insulating barrier.
Further, described cable core layer comprises four cable cores, and four cable cores are distributed in fire-resistant composite band, and with described fire-resistant composite band inscribe, two cable cores adjacent in four cable cores are mutually circumscribed.
Preferably, described inner sandwich layer is that many soft copper silks once restraint conjunction, repeatedly regularly strandedly to form.
Inner sandwich layer outer surface of the present utility model is extruded with ceramic low-smoke halogen-free polyolefin insulating barrier, without the need to wrapped mica tape; Cable core layer is filled and is used ceramic fire-resistant fire prevention gasket for packing and the fire-resistant composite band of wrapped ceramic; Thermoplastic low-smoke halide-free polyolefin sheath layer is extruded outside cable core, relative to traditional Mica tape low-smoke halogen-free polyolefin fire-resisting cable, its advantage is: can generate hard ceramic-like duricrust under flame calcination or hot conditions, duricrust not melting, not drip, can water resistant spray and mechanical shock, and there is extraordinary heat insulation fire insulation effect, can ensure that electric power and information in case of fire control unimpeded, for personnel escape and fire-fighting and rescue strive for the valuable time.Due to without the need to wrapped mica tape, environment friendly and pollution-free, the place that public fire protection, fire protection requirement are very high can be widely used in, particularly in the automatic safe fire-fighting system in some skyscrapers, hotel, hospital, cinema, megastore, oil platform, mine, metallurgy, boats and ships, power station, subway, airport, station, tunnel etc. and emergency power supply system, as a kind of novel fireproof environmental cable of electric energy and information transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Now by reference to the accompanying drawings, the utility model is described in detail.
With reference to accompanying drawing 1, a kind of ceramic low-smoke halogen-free polyolefin insulation fireproof environmental cable, be provided with cable core layer successively from the inside to the outside, fire-resistant composite band 4 and restrictive coating 5, described cable core layer comprises four cable cores, each described cable core comprises inner sandwich layer 1, inner sandwich layer 1 once restraints conjunction for many soft copper silks, repeatedly regularly strandedly to form, each described inner sandwich layer outer surface is extruded with insulating barrier 2, four cable cores are distributed in fire-resistant composite band 4, and with described fire-resistant composite band inscribe, two cable cores adjacent in four cable cores are mutually circumscribed, fire-resistant fire prevention gasket for packing 3 is filled with between multiple described cable core, fire-resistant fire prevention gasket for packing 3 is the fire-resistant fire prevention gasket for packing of ceramic, insulating barrier 2 is ceramic low-smoke halogen-free polyolefin insulating barrier.Hard ceramic-like duricrust can be generated under flame calcination or hot conditions, duricrust not melting, not drip, can water resistant spray and mechanical shock, and there is extraordinary heat insulation fire insulation effect, can ensure that electric power and information in case of fire control unimpeded, for personnel escape and fire-fighting and rescue strive for the valuable time.
During production of the present utility model, by copper bar after wire drawing and annealing, then carry out strand system, extruded insulation, after-combustion distribution and spark examination, ceramic gasket for packing is wrapped in ceramic composite band stranding, finally extrude sheath, equipment only need adopt common polyolefin electric wire and cable material process equipment, one-shot forming, technique is simple, can continuous seepage, compare Ceramic silicon rubber and do not need post bake or steam vulcanization (cure), energy consumption is less, and technological operation is simpler, and production cost is lower.
Above-described the utility model execution mode, does not form the restriction to the utility model protection range.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
Claims (2)
