Abstract
The utility model discloses a mineral-insulated fireproof cable which comprises a plurality of sets of cores. The plurality of sets of cores are tightly wrapped by a taped covering; a metal covering is wrapped over the taped covering; and the taped covering is made from an inorganic mineral material. The mineral-insulated fireproof cable provided by the utility model has good conductivity and excellent flame resistance and does not pose great harm to a human body when a fire hazard occurs.
Description
Technical field
The utility model relates to a kind of mineral insulated cable.
Background technology
Cable is the most widely equipment that delivery of electrical energy uses, yet in daily life, the fail safe that electric energy uses is an extremely concerned problem.In the delivery of electrical energy process, if there is short circuit or electric leakage, the accumulation of the heat outer coating layer of conductor that finally ignites on the conductor, thus ignite other combustibles, make fire out of control, another situation is that 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, therefore existing cable in use, its security performance arrives assurance scarcely ever, demands urgently improving.
The utility model content
For the problem that prior art exists, the purpose of this utility model 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 occurs, also can not cause large damage to human body.
For reaching this purpose, the utility model by the following technical solutions:
Propose a kind of mineral insulated cable, comprise many group cores, organize described core more and adopt lapping layer to wrap, described lapping layer lays oversheath outward, and described lapping layer adopts inorganic mineral material to make, and described oversheath adopts the low smoke, zero halogen material to make.
In described lapping layer, between described core, be provided with packed layer, described packed layer adopts fire-retardant mineral compound to make.
The insulating barrier that described core comprises conductor and coats described conductor, described conductor adopt that many one metal wires are stranded to be formed, and described insulating barrier adopts mica material to make.
Different described insulating barriers have different colors.
Core comprises the insulating barrier of conductor and coating conductor, and conductor adopts that many one metal wires are stranded to be formed, and insulating barrier adopts mica material to make.
Different insulating barriers has different colors.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
A kind of mineral insulated cable that the utility model proposes, not only electric conductivity is good, and fire resistance is also splendid, possesses higher toughness, even when fire occurs, also can not cause large damage to human body.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment 1:
Wherein: 1, conductor; 2, insulating barrier; 3, packed layer; 4, lapping layer; 5, oversheath.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
A kind of mineral insulated cable is proposed, comprise many group cores, core comprises the insulating barrier 2 of conductor 1 and coating conductor 1, conductor 1 adopts that many one metal wires are stranded to be formed, can improve the tensile property of whole cable, this wire is copper wire, so that this cable possesses preferably electric conductivity, insulating barrier 2 adopts mica material to make, even it is too high to work as 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, also so that can not have influence on the delivery of electrical energy of conductor 1, different insulating barriers 2 have different colors, can make things convenient for wiring operations, many group cores adopt lapping layer 4 to wrap, lapping layer 4 adopts inorganic mineral material to make, in lapping layer 4, between core, be provided with packed layer 3, packed layer 3 adopts fire-retardant mineral compound to make, because lapping layer 4 and packed layer 3 possess flame retardant effect, can will separate in the lapping layer 4 with outside the lapping layer 4, thereby avoid fire spread, lay one deck oversheath 5 outside lapping layer 4, oversheath 5 adopts the low smoke, zero halogen material to make, and not only possesses extremely strong toughness, simultaneously, even ignited by the external world, can not produce the toxic gas that human body is damaged yet, thereby reduce to greatest extent the damage that it causes human body.
The above; it only is the better embodiment of the utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection range of the present utility model.
