Embodiment
By particular specific embodiment, execution mode of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification can be well understood to advantage of the present utility model and effect.
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of fireproof cable comprises the neutral core 4 of three annealed copper conductor wire cores 1 and a soft copper wire, by customer power supply demand, by outside each conductor wire core respectively overlap put up a wrapped inner insulating layer 2, for improving fire protection flame retarding, this inner insulating layer 2 selects the material of environmental protection heatproof flame-retardant type, this environmental protection heatproof flame-retardant shaped material can be the inorganic mineral insulation material containing magnesium oxide or quartz, mica, or the polymer composite of not halogen-containing (as fluorine, chlorine), as common adds with Al (OH)
3with Mg (OH)
2it is the polymer composite of main metal hydrate based flame retardant; All can be used as the heatproof flame-retardant materials'use needed for described fireproof cable.In view of process costs, the mineral insulating material that the temperature tolerance that herein preferably insulate is good, this material effectively can play the fire-retardant effect of oxygen barrier to conductor wire core 1; One deck external insulation layer 3 is extruded outside above-mentioned inner insulating layer 2; form a complete wire; described external insulation layer 3 adopts the material of environmental protection heatproof flame-retardant type to make; fire-proof insulation protection is carried out to described conductor wire core 1; duplicate protection barrier is formed, to improve the fire protection flame retarding of every root wire further together with inner insulating layer 2.By all conductor combination strandings, its cabling process puts up a wrapped internal protective cover 6 at each wire outer bilayer, by 4 wire boundling wrapped one-tenth single line cables; Due to when several conductor combination strandings, space is had between each wire, cause stranding out-of-shape, therefore for guaranteeing the rounding property of cable, a kind of fire prevention of special filling high-temperature resistant material, for fire-proof insulation reliability consideration, the preferred mineral insulating material of selected fire prevention high-temperature resistant material, with further fire protection flame retarding.Finally outside internal protective cover 6, adopt expressing technique, extrude the protective sleeve 7 that one deck is made up of mineral insulating material.
Above-mentioned mineral insulating material halogen, wherein containing magnesium oxide or quartz, the inorganic minerals such as mica, as magnesium oxide has extremely fireproof insulation property, crystal can be changed into through more than 1000 DEG C high temperature sinterings, rise to more than 1500 DEG C and then become dead roasting magnesium oxide (namely said magnesia) or sintered magnesia, also no acidic even if burn under Fire Conditions, the gases such as poison gas are dispersed, and its flue gas is dispersed experimental test light transmittance and is reached more than 80%, far above 60% of common specifications of cables, when fire occurs, personnel escape does not disturb by sight line, its above-mentioned characteristic is better than traditional PVC (polyvinyl chloride) and PE (polyethylene) cable insulation material greatly, the overall temperature resistant grade of fireproof cable after overall stranding can bring up to 1600 DEG C by traditional 950 DEG C.
Further, filler 5 is network structure, and this Web materials can preferred mineral insulating material, high temperature resistant, good permeability, thermal diffusivity strong, adopts this structure can ensure overall roundness and the pliability of cable; When fire occurs, the intensity of a fire can be isolated into little bin one by one, cooling by each reticulated void, effectively prevents fire spreading from expanding.
Further, the environmental protection heatproof flame-retardant material that above-mentioned external insulation layer 3 adopts is porcelain modified high-molecular fire-retardant insulating material, and it specifically adds clay minerals powder filler, constitution controller and other auxiliary agent and is prepared from siliceous macromolecule (as silicon rubber) matrix.This composite material at room temperature has the character of common wiring cable insulation layer material; hard ceramic protective layer is formed when meeting high-temp combustion; isolated flame and fireproof effect can be played; it is a kind of smokeless, nontoxic, heatproof insulating material of not distributing any harmful and noxious substance; porcelain modified high-molecular insulating material adopts conventional extrusion process just can complete; make technique simple, with low cost, safe and reliable.
Further, internal protective cover 6 adopts the coiling of high-strength polyester film to form, and this high-strength polyester film is also a kind of fire prevention high-temperature resistant material well; above-mentioned wire is by the parcel of internal protective cover 6; further increase the rounding property of cable, reduce the external diameter of cable, save material.
Further, above-mentioned conductor wire core 1, neutral core 4 are multicore conductor wire core, twist again form through drawing process, and conductor wire core adopts stranded copper wire stranded, and even thickness, any surface finish, length are grown, had flexibility.
Further, except above-mentioned annealed copper does except conductor wire core, conductor wire core 1 also can adopt new rare earth aluminum alloy conductor to make, and it is lightweight, low price, soft flexible, can ensure that cable in use has higher flexible performance.
Above-mentioned cable conductor can make also three or 5 as required, is not limited to 4 wire form of above-described embodiment.
The fireproof cable that the utility model provides, insulating material used is all environmental protection heatproof flame-retardant material, mineral insulating material is utilized effectively to avoid the release of toxic gas smog, strengthen cable heatproof fire line, multicore annealed copper conductor compacting stranded bundle forms, mineral fire-retardant insulating material is adopted to put up wrapped or extrude covering each conductor wire core, conductor wire core can be effectively stoped to corrode by the burning of fire, improve the resistance to gentle fire protecting performance of cable, and guarantee the rounding aesthetic property of cable, flexibility and useful life; Meanwhile, netted mineral-filled thing is set, strengthens cable dissipate heat effect and heatproof fire-protection rating further, make the safer environmental protection of cable.To sum up, this fireproof cable has the excellent serviceability of heatproof flame-retardant, safety and environmental protection, can effectively stop fire to the erosion of cable when fire occurs, be beneficial to personal security escape and evacuation, when high-rise building with fire disaster, the combustion product gases light transmittance of this fireproof cable more than 80% is especially for fire-fighting and rescue has won the quality time.In addition, be provided with the fireproof cable of the metal sleeves such as aluminium alloy relative to other, under the prerequisite fully reaching fire protection flame retarding requirement, the utility model manufacture is more simple, and cost is lower, is more suitable for applying.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
