Abstract
The utility model discloses a power cable used for fire safety. The power cable comprises a cable core. The cable core is formed through intertwisting several insulation wire cores. A glass fiber rope fire prevention filling layer is arranged in a gap of the cable core. An integration protection layer wraps the cable core. An environment-friendly type sheath layer is extruded on an outermost layer of the cable core. The insulation wire cores are formed by conductors, conductor fireproof layers and insulating layers, wherein the conductor fireproof layers and the insulating layers are successively extruded out of the conductors. A test proves that the power cable can completely satisfy a flame-retardation and fireproof requirement and a product technology is simple. Compared to the existing fireproof cable, by using the power cable of the utility model, fire prevention performance of the cable is greatly reinforced; production is easy; an outer sheath material adopts a halogen-free fire-resistant material and an environmental protection effect is increased. Simultaneously, raw materials used for producing the product are common and cost is low. With the above improvement, product usage performance and enterprise benefits are greatly increased.
Description
Technical field
The utility model belongs to power cable field, is specifically related to a kind of security against fire power cable.
Background technology
Along with social development, the progress of science and technology, numerous power plant, smelter, oil play are to large-scale grouping of the world economy future development, skyscraper, public entertainment place, subway and underground street etc. continue to bring out, and its power consumption grows with each passing day, and the kind of electric wire and consumption be corresponding increase also.Electric wire both can transmission & distribution electric energy, transmission of information, was again " blasting fuse " of fire hazardous, yet once common cable is burned and cannot switch on when actual breaking out of fire.But during many important events contingency breaking out of fires, the illumination of evacuating personnel, passage, fire protection alarm device, automatic fire-fighting facility and other emergency set all require cable can keep normal power-up at the appointed time when fire occurs.Therefore, people work out fireproof cable.
Fireproof cable: refer to that, under regulation experimental condition, sample is burned in flame, still keep within a certain period of time the performance of normal operation.Its basic feature is exactly: power cable still can maintain the normal work of this circuit a period of time under burning condition.Be exactly generally, fireproof power cable can maintain the normal power supply of a period of time when fire occurs, and to maintain illumination and signal transmission, protection personnel have time enough safe escape, and are beneficial to fire extinguishing and reduce the loss.
Common fireproof cable adopts wrapped fireproof mica band structure on cable conductor, can not guarantee effectively, reliably cable normally operation in flame situation.
Utility model content
The purpose of this utility model is to provide a kind of security against fire power cable, has improved the fire resistance structure of cable own, and not only processing technology is simple, and greatly strengthens fireproofing of cable.
A kind of security against fire power cable described in the utility model, comprises cable core, and this cable core is some stranded the forming of insulated wire cores again; The gap of cable core is provided with glass fiber rope fire prevention packed layer, cable core outer cladding insulation Comprehensive Preventing sheath, and cable core outermost layer extrudes environment-friendly type restrictive coating; Described insulated wire cores is by conductor and be extruded in successively conductor flame retardant coating and the insulating barrier outside conductor.
Further improve, described insulated wire cores is three to five or more than five.
Further improve, described insulated wire cores is three, and it is shaped as circular or fan-shaped.
Further improve, described insulated wire cores is five, and wherein one is circular, and four is fan-shaped or watt shape.
Further improve, described conductor flame retardant coating is mineral matter or mineral matter composite band.
Further improve, to be ceramic silastic material form with the common formation of low-smoke non-halogen flame-retardant band or ceramic silastic material and glass fibre belt described insulation Comprehensive Preventing sheath jointly.
Further improve, described environment-friendly type restrictive coating is low-smoke halogen-free polyolefin fire retardant jacket.
The beneficial effects of the utility model are:
The utility model meets flame-retardant requirement completely through evidence, and Product Process is simple, compare with current existing fireproof cable, greatly strengthen fireproofing of cable, be easy to produce, jacket material adopts Halogen refractory material, increased environment protecting, meanwhile, this product raw materials for production used are comparatively common, with low cost.The improvement of above aspect, has improved product serviceability and the performance of enterprises greatly.
Accompanying drawing explanation
Fig. 1 is that the utility model conductor is the structural representation of three.
Fig. 2 is that the utility model conductor is the structural representation of five.
Embodiment
As shown in Figure 1, a kind of security against fire power cable described in the utility model, comprises cable core, and this cable core is by three stranded forming of round insulation core; The gap of cable core is provided with glass fiber rope fire prevention packed layer 6, cable core outer cladding insulation Comprehensive Preventing sheath 4, and cable core outermost layer extrudes environment-friendly type restrictive coating 5; Described insulated wire cores is by circular conductor 1 and be extruded in successively the conductor flame retardant coating 2 and insulating barrier 3 outside conductor 1.
As shown in Figure 2, be with Fig. 1 difference, its cable core is by five stranded forming of insulated wire cores, and wherein center is a circular insulated wire cores, the coated four fan-shaped insulated wire cores of the outer surrounding of insulated wire cores at center; Such structure does not just need to be provided with packed layer.
Described conductor flame retardant coating 2 is mineral matter or mineral matter composite band; Described insulation Comprehensive Preventing sheath 4 forms jointly for the common formation of ceramic silastic material and low-smoke non-halogen flame-retardant band or ceramic silastic material and glass fibre belt; Described environment-friendly type restrictive coating 5 is low-smoke halogen-free polyolefin fire retardant jacket.
Principle of the present utility model:
Conductor flame retardant coating is closely coated on conductor; insulating barrier is close on conductor flame retardant coating; the employing of insulation integrated protection layer extrudes ceramic silastic material and adds wrapped low smoke and zero halogen band or glass fibre belt; ceramic silicon rubber starts hardening under 350 ℃ and above flame or nonflame condition; along with temperature raises; rapidly qualitative change is the complete housing that ceramic-like is hard, and hard complete housing plays a very good protection to circuit, guarantees unobstructed under fire condition of circuit.Low smoke and zero halogen band or glass fibre belt pack tightly ceramic silicon rubber, can effectively prevent when ceramic silicon rubber is subject to thermal crystalline " dry linting " phenomenon of producing due to vibrations or other factors, and do not produce halogen during burning.Oversheath adopts fire-resistant polyolefin material, can protect cable not damaged by extraneous mechanical force when cable normally moves; Under burned environment, fire-resistant polyolefin material expands rapidly, forms fine and close porous carbon layer, plays flame-retardant effect, and fire-resistant polyolefin material combustion do not produce halogen, plays certain environment protecting.
The utility model provides a kind of security against fire power cable; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
