Abstract
The invention discloses a flexible environment-friendly fireproof cable. The flexible environment-friendly fireproof cable is composed of conductive cable cores, a monitoring cable core, a nanometer anti-flaming insulation layer and a low-smoke halogen-free outer sheath, wherein a woven fastening layer and a ceramic fluorine rubber insulation layer are sequentially wrapped in two rows of strand copper conductors from exterior to interior to form each conductive cable core, a drainage cable core is arranged in each woven fastening layer, and one monitoring cable core is closely wrapped in the four conductive cable cores in an extruding mode; the monitoring cable core is wrapped in an anti-flaming glass fiber woven layer; the four conductive cable cores are wrapped in the nanometer anti-flaming insulation layer; the nanometer antiflaming insulation layer is wrapped in the low-smoke halogen-free outer sheath in an extruding mode. The flexible environment-friendly fireproof cable has the advantages of being stable in structure, good in moving flexibility and heat insulating and anti-flaming performance, free of halogen and poison, environmentally friendly and capable of providing a reliable guarantee for wide popularization.
Description
Technical field
The present invention relates to cable, relate in particular to a kind of flexible environment friendly fireproof cable.
Background technology
Fire safety has become a kind of important leverage measure that ensures national economy fast development, and preventing electric fire has become the most important thing, realizes this High-Interest Object, and insulated cable becomes unique first-selection.Electric wire is one of important channel of initiation fire, according to incompletely statistics, the toxic gas death by suffocation discharging while having 1/3rd be because suck electric wire burning in the fire causing because of electric wire in the fire occurring in dead personnel, the fire therefore being caused by electric wire can not be ignored.The disaster that fire brings to the mankind is heavy, and loss is huge, and along with the development of economy and urban construction, fire damage is in rising trend, and therefore all prevention of fires is very paid attention to both at home and abroad.How to stop the burning of electric wire, even gone back LSZH by naked light burning, this is the large problem of electric wire manufacturing.China is developing and is producing multiple fire-resistant, fire prevention and other kinds flame-proof environmental protection cable closely for many years.During due to non-environment-friendly type cable fire, produce a large amount of toxic and harmfuls and cause personnel death, and equipment is undermined the harm that smog seriously makes personnel not withdraw in time, user has proposed cable not only should have good fire resistance, and burning after produce gas in without hydracid (pernicious gas), and the amount of being fuming is low, best should be that cable possesses fire prevention and fire-resistant function under fire condition, has developed thus fire-type environment-friendly cable.
Summary of the invention
In order to meet above-mentioned requirements, the object of the invention is to provide a kind of flexible environment friendly fireproof cable.
The solution of the present invention is as follows: a kind of flexible environment friendly fireproof cable, it is made up of conductor wire core, monitoring core, nano flame retardant insulating barrier and low smoke and zero halogen oversheath, described conductor wire core is to be coated from outside to inside successively two row's twisted copper conductors by braiding fastened layer and ceramic fluorubber insulating barrier to form, in described braiding fastened layer, be provided with a drainage core, four conductor wire cores closely extrude a monitoring core; Described monitoring core is coated with combustion-proof glass fiber braid; Described nano flame retardant insulating barrier is coated on outside four conductor wire cores; Described low smoke and zero halogen oversheath is extruded on nano flame retardant insulating barrier.
The quantity of the every row's twisted copper conductors of described two row's twisted copper conductors is 4, horizontally.
Beneficial effect of the present invention: the flexible environment friendly fireproof cable that the advantage of this cable is Stability Analysis of Structures, mobile flexibility is good, heat-insulating flame-retardant is good, Halogen is nontoxic, for universal and popularization widely provides reliable assurance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Wherein: 1, twisted copper conductors; 2, ceramic fluorubber insulating barrier; 3, braiding fastened layer; 4, nano flame retardant insulating barrier; 5, low smoke and zero halogen oversheath; 6, monitoring core; 7, combustion-proof glass fiber braid; 8, drainage core.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of flexible environment friendly fireproof cable, it is made up of conductor wire core, monitoring core, nano flame retardant insulating barrier 4 and low smoke and zero halogen oversheath 5, described conductor wire core is to be coated from outside to inside successively two row's twisted copper conductors 1 by braiding fastened layer 3 and ceramic fluorubber insulating barrier 2 to form, in described braiding fastened layer 3, be provided with 8, four conductor wire cores of a drainage core and closely extrude a monitoring core 6; Described monitoring core 6 is coated with combustion-proof glass fiber braid 7; Described nano flame retardant insulating barrier 4 is coated on outside four conductor wire cores; Described low smoke and zero halogen oversheath 5 is extruded on nano flame retardant insulating barrier 4.
The quantity of the every row's twisted copper conductors 1 of described two row's twisted copper conductors 1 is 4, horizontally.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
