Abstract
The invention discloses a fireproof mineral insulated cable which comprises a plurality of groups of wire cores. The groups of wire cores are wrapped by a lapping layer, a metal sleeve is wrapped on the outside of the lapping layer, and the lapping layer is made of inorganic mineral materials. The fireproof mineral insulated cable not only is good in conductivity, but also is excellent in flame retardant property, and cannot cause great injury to human bodies in case of fire disaster.
Description
Technical field
The present invention relates to a kind of mineral insulated cable.
Background technology
Cable is the equipment the most widely that electric energy transmitting is used, yet in daily life, the fail safe that electric energy uses is a problem that the utmost point is paid close attention to.In the electric energy transmitting process, if short circuit or electric leakage, the accumulation of the heat outer coating layer of conductor that finally ignites on the conductor; Thereby ignite other combustibles, make fire out of control, a kind of in addition situation is; Other combustibles catch fire to ignite and are coated on the outer coating layer of cable conductor, thereby cause short circuit electric leakage etc., thereby make cable become the accomplice that fire further spreads; So existing cable in use, its security performance arrives assurance scarcely ever, demands urgently improving.
Summary of the invention
Problem to prior art exists the objective of the invention is to propose a kind of mineral insulated cable, and not only electric conductivity is good, and fire resistance is also splendid, even when fire takes place, also can not cause big damage to human body.
For reaching this purpose, the present invention adopts following technical scheme:
Propose a kind of mineral insulated cable, comprise many group cores, organize said core more and adopt lapping layer to wrap, said lapping layer lays oversheath outward, and said lapping layer adopts inorganic mineral material to process, and said oversheath adopts the low smoke, zero halogen material to process.
In said lapping layer, between said core, be provided with packed layer, said packed layer adopts fire-retardant mineral compound to process.
The insulating barrier that said core comprises conductor and coats said conductor, said conductor adopt that many one metal wires are stranded to form, and said insulating barrier adopts mica material to process.
Different said insulating barriers have various colors.
Core comprises the insulating barrier of conductor and coating conductor, and conductor adopts that many one metal wires are stranded to form, and insulating barrier adopts mica material to process.
Different insulating barriers have various colors.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
A kind of mineral insulated cable that the present invention proposes, not only electric conductivity is good, and fire resistance is also splendid, possesses high toughness, even when fire takes place, also can not cause big damage to human body.
Description of drawings
Fig. 1 is the overall structure sketch map of the embodiment of the invention 1:
Wherein: 1, conductor; 2, insulating barrier; 3, packed layer; 4, lapping layer; 5, oversheath.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment:
Propose a kind of mineral insulated cable, comprise many group cores, core comprises the insulating barrier 2 of conductor 1 and coating conductor 1, and conductor 1 adopts that many one metal wires are stranded to form; Can improve the tensile property of whole cable, this wire is a copper wire, makes this cable possess electric conductivity preferably, and insulating barrier 2 adopts mica material to process; Even too high when conductor 1 portion temperature, this insulating barrier 2 can not burn yet, when extraneous breaking out of fire, because the obstruct of insulating barrier 2; The also feasible electric energy transmitting that can not have influence on conductor 1, different insulating barriers 2 have various colors, can make things convenient for wiring operations; Many group cores adopt lapping layer 4 to wrap, and lapping layer 4 adopts inorganic mineral material to process, in lapping layer 4; Between core, be provided with packed layer 3, packed layer 3 adopts fire-retardant mineral compound to process, because lapping layer 4 and packed layer 3 possess flame retardant effect; Can with in the lapping layer 4 with 4 outer separating of lapping layer, thereby avoid fire spread, outside lapping layer 4, lay one deck oversheath 5; Oversheath 5 adopts the low smoke, zero halogen material to process, and not only possesses extremely strong toughness, simultaneously; Even ignited, can not produce the toxic gas that human body is damaged yet, thereby reduce the damage that it causes human body to greatest extent by the external world.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
