Abstract
The utility model discloses a copper wire armored fireproof cable comprising a cable core which is stranded by three insulated wire cores. A filling layer is arranged in gaps of the cable core, the cable core is sequentially wrapped by a belting layer, an inner sheath layer made of flame-retardant polyurethane material and a shielding layer adopting a soft round copper wire armored shielding structure, and an outer sheath made of flame-retardant polyurethane material is extruded at the outmost layer of the cable. Each insulated wire core is composed of a conductor, a composite mica tape and an insulating layer, wherein the composite mica tape and the insulating layer are sequentially wrapped outside the conductor. The insulation of the copper wire armored fireproof cable is composite novel flame-retardant high-density polyethylene which is a novel flame-retardant insulation material, has good flame retardance (the oxygen index is above 27), produces a small volume of smoke, avoids the 'molten drop' phenomenon occurring in the combustion process of polyethylene and has high tensile strength. The 'molten drop' phenomenon of polyethylene material in the combustion process is avoided. In addition, the copper wire armored fireproof cable has the advantages of being resistant to high temperature, pressure-resistant, oil-resistant, acid/alkali-resistant, anti-electromagnetic-interference and the like.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of copper wire armouring fire-resisting cable.
Background technology
Along with the continuous progress of society, the raising of living standards of the people, people more and more pay attention to the safety in the life, but people are pursuing high-quality life, enjoy the emporium, in the time of clusterings such as grand theater life, fire safety is also more and more important and urgent, reporting of comprehensive each conflagration, the wherein spontaneous combustion of electric wire and the fire that causes accounts for significant proportion, and at fire again because the reason of electric wire causes the ratio of personnel self injures and deaths also to occupy very big ratio, for example, the very short time was born the electric wire generation electric power transfer interruption of electric power transfer after fire took place, cause elevator, the illumination cisco unity malfunction causes injures and deaths and people are tried in any path one could without heeding which one chose.
And the traditional cable great majority adopt combustible material, and the burning back produces solid granule and forms smog, has reduced light transmittance, influence people's escape during breaking out of fire, search and rescue, and non-refractory, thereby be difficult to ensure communication, the safe operation of electric power under fire condition; In addition, the acid gas that discharges behind the cable fire and toxic gas cause personal life danger and " secondary harm ".
The utility model content
Technical problem to be solved in the utility model provides a kind of high temperature resistant, withstand voltage, oil resistant, acid and alkali-resistance, anti-electromagnetic interference, copper wire armouring shielding fire-resisting cable.
A kind of copper wire armouring fire-resisting cable described in the utility model comprises cable core, and cable core is by stranded the forming of some eradication edge cores; Cable core internal pore place is provided with packed layer, wrapped belting layer, sheath, screen successively outside cable core, and the cable outermost layer extrudes oversheath; Described insulated wire cores by conductor and successively wrapped combined mica band, insulating barrier outside conductor constitute.
Further improve, described conductor is real core conductor or stranded conductor again, and belting layer is glass fibre belt, and packed layer is filled for the glass rope; Described screen is soft round copper wire armouring shielding construction.
The beneficial effects of the utility model:
1, owing to adopt the combined mica band, can make the fire resistance rating of cable reach the fire-resistant level of A level (950 1 1000 ℃);
2, insulation has solved " molten " phenomenon that polyethylene produces for extruding the fire-retardant high density polyethylene (HDPE) of NEW TYPE OF COMPOSITE when burning;
3, adopt soft round copper wire to make the armouring screen, can play protection cable core and the double action of resisting external electromagnetic interference;
4, the cable jacket material adopts flame retardant polyurethane, has improved the applicability of cable, is applicable to various environment better.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of copper wire armouring fire-resisting cable described in the utility model comprises cable core, and cable core is to thoroughly do away with stranded the forming of edge core by three; Cable core internal pore place is provided with packed layer 5, outside cable core successively wrapped belting layer 4, adopt the flame retardant polyurethane material sheath 6, adopt the screen 7 of soft round copper wire armouring shielding construction, the cable outermost layer extrudes the oversheath 8 that adopts the flame retardant polyurethane material; Described insulated wire cores by conductor 1 and successively wrapped outside conductor 1 combined mica band 2, adopt the insulating barrier 3 of the fire-retardant high-density polyethylene material of new composite to constitute.
Technology of the present utility model is:
Conductor of the present utility model adopts the 1st kind of real core conductor or the 2nd kind of stranded conductor among the national standard GB ∕ T 3956-2008 " conductor of cable ", at the peripheral wrapped two layers of combined mica band of conductor, it is different from phlogopite band and synthetic mica tape, its remarkable characteristic is that the coefficient of expansion is little, dielectric strength is big, resistivity is high and dielectric constant is even, the thermal endurance class height is its main feature, can reach the fire-resistant level of A level (950 1 1000 ℃).The utility model insulation is novel high-density composite flame-proof polyethylene, and it has anti-flammability (oxygen index reaches more than 27), smoke-suppressing, hot strength preferably, has solved " molten " phenomenon that polythene material occurs in combustion process.The utility model is filled with band and is adopted glass rope and glass fibre belt, and they are the incombustible materials of generally acknowledging.The utility model adopts soft round copper wire armouring shielding construction, can play the protection cable core electromagnetic interference double action outside with opposing; The utility model external sheath layer is for extruding flame resistance polyurethane elastomer, withstand voltage, the oil resistant that has except polyurethane material, acid and alkali-resistance, softness, the wideer performances such as the temperature scope of application, will make cable possess outstanding fire resistance.
The utility model provides a kind of thinking and implementation method of copper wire armouring fire-resisting cable; concrete application approach is a lot; the above only is preferred implementation 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.
