Description
Technical field
The utility model belongs to power cable field, is specifically related to a kind of New insulated fire proof 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.In addition, once the damaged replacement just not having of core must more renew again, so, artificial and Master Cost has just increased a lot.
Utility model content
The purpose of this utility model is to provide a kind of New insulated fire proof power cable, has improved the fire resistance structure of cable own, and not only processing technology is simple, cost-saving, and greatly strengthens fireproofing of cable.
A kind of New insulated fire proof power cable described in the utility model, comprises cable core, and this cable core is by stranded the forming of insulated wire cores of two kinds of small one and large one different structures; The gap of cable core is provided with glass fiber rope fire prevention packed layer, cable core outer cladding fire-resistant wrapping tape layer, and outermost extrudes outer jacket; The large insulated wire cores of described structure consists of conductor and the insulating barrier, the fireprotection layer that are extruded in outside conductor; The little insulated wire cores of described structure consists of conductor and the insulating barrier that is extruded in outside conductor.
Further improve, the insulated wire cores that described structure is large is more than two or two.
Further improve, the insulated wire cores that described structure is little is more than two or two.
Further improve, described fireprotection layer is mineral matter or mineral matter composite band.
Further improve, described fire-resistant wrapping tape layer is mineral matter composite band.
Further improve, described outer jacket is low-smoke halogen-free polyolefin fire retardant jacket.
Beneficial effect of the present invention is:
The utility model meets flame-retardant requirement completely through evidence, and Product Process is simple, compare with current existing fireproof cable, adopt double-deck fireprotection layer, greatly strengthen fireproofing of cable, be easy to produce, outer sheath material adopts Halogen refractory material, has increased environment protecting, simultaneously, this product raw materials for production used are comparatively common, with low cost.Cable core adopts the insulated wire cores of small one and large one different structure, when large core damages, can replace little use, has saved cost; The improvement of above aspect, has improved product serviceability and the performance of enterprises greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of New insulated fire proof power cable described in the utility model, comprises cable core, and this cable core is by stranded the forming of insulated wire cores of two kinds of small one and large one different structures; The gap of cable core is provided with glass fiber rope fire prevention packed layer 4, cable core outer cladding fire-resistant wrapping tape layer 5, and outermost extrudes outer jacket 6; The large insulated wire cores of described structure consists of conductor 1 and the insulating barrier 2, the fireprotection layer 3 that are extruded in outside conductor 1; The little insulated wire cores of described structure consists of conductor 1 and the insulating barrier 2 that is extruded in outside conductor 1.
Described fireprotection layer 3 is mineral matter or mineral matter composite band; Described fire-resistant wrapping tape layer 5 is mineral matter composite band; Described outer jacket 6 is low-smoke halogen-free polyolefin fire retardant jacket.
The utility model provides a kind of New insulated fire proof power cable; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
