Abstract
本实用新型公开一种柔性矿物绝缘防火电缆，包含多组线芯，多组所述线芯采用绕包层裹紧，在所述绕包层外包裹金属套，所述绕包层采用无机矿物材料制成。不仅导电性能良好，阻燃性能也极佳，具备较高的韧性和良好的屏蔽性能，即使当火灾发生时，也不会对人体造成大的损伤。
The utility model discloses a flexible mineral insulated fireproof cable, which comprises a plurality of groups of wire cores, and the plurality of groups of wire cores are tightly wrapped by wrapping layers, and a metal sleeve is wrapped outside the wrapping layers, and the wrapping layers are made of inorganic minerals material. It not only has good electrical conductivity, but also has excellent flame retardancy, high toughness and good shielding performance. Even when a fire occurs, it will not cause major damage to the human body.
Description
Technical field
The utility model relates to a kind of flexible 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 flexible mineral insulated cable, and not only electric conductivity is good, fire resistance is also splendid, possess higher toughness and good shielding properties, 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 flexible mineral insulated cable, comprise many group cores, organize core more and adopt lapping layer to wrap, at lapping layer outer wrapping metallic sheath, lapping layer adopts inorganic mineral material to make.
In lapping layer, between core, be provided with packed layer, packed layer adopts fire-retardant mineral compound to make.
Be provided with the helical form embossing at metallic sheath.
Lay oversheath outside metallic sheath, oversheath adopts the low smoke, zero halogen material to make.
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 flexible mineral insulated cable that the utility model proposes, not only electric conductivity is good, and fire resistance is also splendid, possesses higher toughness and good shielding properties, 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, metallic sheath; 6, oversheath.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
Embodiment 1
A kind of flexible 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; at lapping layer 4 outer wrapping metallic sheaths 5; this metallic sheath 5 is copper sheathing; the effect of metallic sheath 5 not only can be strengthened the intensity of cable; so that metallic sheath 5 is with the interior mechanical damage that can not be subject to coming from the external world; simultaneously; metallic sheath 5 plays good shielding action; simultaneously; metallic sheath 5 can separate metallic sheath 5 with interior environment and the external world; even extraneous breaking out of fire can not have influence on the normal use of cable, simultaneously yet; for preventing that metallic sheath 5 from causing harmful effect with rigid contact the between the external device to metallic sheath 5 and external device; therefore lay the oversheath 6 that one deck is used for buffer protection lid metallic sheath 5 outside metallic sheath 5, oversheath 6 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.
