Abstract
The utility model discloses an environment-friendly ceramic fireproofing fire-resistant power cable which comprises a cable core formed by a plurality of insulated wire cores. A packing layer is arranged at a gap position of the cable core, a fire-resistant belting layer, an isolated layer and a metal armor layer are lapped outside the cable core sequentially, and an outer protective sleeve is extruded on the most outer layer of the cable core. Each insulated wire core is formed by a conductor, a conductor fire-resistant layer and an insulated layer, and the conductor fire-resistant layer and the insulated layer are sequentially wrapped on the outside of the conductor. The environment-friendly ceramic fireproofing fire-resistant power cable mainly uses a ceramic fireproofing fire-resistant composite belt taping to replace an extruding ceramic silicon rubber fireproofing layer, reduces production processes, greatly improves production efficiency, lower rate of quality problems of products, simultaneously reduces material using quantity, reduces material cost, and increases environment-friendly effects due to the fact that the ceramic fireproofing fire-resistant composite belt, an isolated sleeve and the outer protective sleeve are all made of halogen-free fire-resistant materials.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of enviroment protective ceramic chemoprevention fire fireproof power cable.
Background technology
Along with the development of society, 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.But electric wire is transmission ﹠ distribution electric energy, transmission of information both, is again " blasting fuse " of fire hazardous, just can't switch on yet common cable is in a single day burned 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 refers to that under the regulation experimental condition, sample is burned in flame, still keeps within a certain period of time the performance of normal operation.Its basic feature is exactly: power cable still can be kept the normal operation of this circuit a period of time under burning condition.Be exactly generally, fireproof power cable can be kept the normal power supply of a period of time when fire occurs, and to keep illumination and signal transmission, the protection personnel have the time enough safe escape, and are beneficial to fire extinguishing and reduce the loss.
At present, ceramic silicone rubber fireproof power cable Shortcomings part both domestic and external is, its ceramic silicone rubber fireproof layer all adopts the mode of extruding, this extrudes mode, and not only to have increased the processing technology of production process, product complicated, and increase the rejection number of material, contaminated environment causes the waste of material, has increased production cost.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of production process, enviroment protective ceramic chemoprevention fire fireproof power cable that product processing technique rejection number, production cost simple, that reduce material is low of having reduced.
A kind of enviroment protective ceramic chemoprevention fire fireproof power cable described in the utility model comprises: cable core, and its cable core is by stranded the forming of some eradication edge cores; Be provided with packed layer in the cable core gap, wrapped fire-resistant wrapping tape layer, separator and metal armouring layer successively outside cable core extrude oversheath at the cable core outermost layer.
Described insulated wire cores is four; Its insulated wire cores is by conductor and be coated on successively conductor outer conductor flame retardant coating, insulating barrier and consist of.
Described packed layer is comprised of the asbestos gasket for packing; Described fire-resistant wrapping tape layer is comprised of two layers of ceramic fireproof＝fire-proof composite band.
The beneficial effects of the utility model are:
compared with prior art, the enviroment protective ceramic chemoprevention fire fireproof power cable of the utility model design, satisfy the flame-retardant requirement fully through evidence, and Product Process is simple, compare with present existing ceramic silicone rubber fireproof cable, utilize ceramic fireproof＝fire-proof composite band wrapped replacement to extrude ceramic silicone rubber fireproof layer, reduced production process, when production efficiency is improved greatly, also reduced the probability that quality problems appear in product, simultaneously, this technique has reduced material usage, reduced material cost, and ceramic fireproof＝fire-proof composite band and separation sleeve, jacket material is the Halogen refractory material, increased environment protecting.The improvement of above aspect has improved product serviceability and the performance of enterprises greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, a kind of enviroment protective ceramic chemoprevention fire fireproof power cable described in the utility model, this cable comprises respectively conductor 1, conductor flame retardant coating 2, insulating barrier 3, packed layer 4, fire-resistant wrapping tape layer 5, separation sleeve 6, metal armouring layer 7, oversheath 8 from inside to outside; Wherein conductor 1 has four, and diameter is identical.Described conductor 1 and the conductor flame retardant coating 2, the insulating barrier 3 that are coated on outside conductor 1 form eradication edge cores, four thoroughly do away with the edge core is twisted into cable core, wrapped fire-resistant wrapping tape layer 5 during stranding, the gap between fire-resistant wrapping tape layer 5 and insulated wire cores is provided with packed layer 4, fills and adopts asbestos cord.Fire-resistant wrapping tape layer 5 is met by the calendering of ceramic fireproof silicone rubber and high temperature resistance glass fiber cloth and forms; begin hardening under 350 ℃ and above flame or nonflame condition; along with temperature raises; rapidly by the hard complete housing of Low fire ceramic shape; hard complete housing and metal armouring layer play a very good protection to circuit, guarantee unobstructed under fire condition of circuit.Adopt the separation sleeve 6 of fire-resistant polyolefin material in fire-resistant wrapping tape layer 5 outer cladding, metal armouring layer 7 is arranged outside separation sleeve 6, the outer oversheath 8 that adopts the fire-resistant polyolefin material that extrudes of metal armouring layer 7.Oversheath 7 and metal armouring layer 8 can protect cable not damaged by extraneous mechanical force when cable normally moves; Under burned environment, the fire-resistant polyolefin jacket material expands rapidly, forms fine and close porous carbon layer, plays the flame-retardant effect, and the burned halogen that do not produce of fire-resistant polyolefin jacket material, plays certain environment protecting.
The utility model provides a kind of enviroment protective ceramic chemoprevention fire fireproof power cable version and implementation method; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
