Copper wire it is well-regulated, by concentric type, and successive layers form according to different direction process；The cable outer layer with absolutely
Space between edge layer extrudes filling by fire proofing material.
Further, the flame retardant coating is the overlapping wrapped composition of fluorine gold synthetic mica tape.
Further, the insulating barrier is to extrude silane type halogen-free and low-smoke flame-retardant polyolefin.
Further, the insulating barrier is handled by crosslinked with silicane, and linear molecular structure is changed into solid netted molecule
Structure.
Further, the fire proofing material uses ceramic halogen-free and low-smoke flame-retardant polyolefin material.
Yet further, the cable outer layer is halogen-free and low-smoke flame-retardant polyolefin material.
The utility model has the beneficial effect that：Compared with prior art, it is simple in construction, it is not necessary to which that waterproof layer is additionally set, absolutely
Edge layer is handled to extrude silane type halogen-free and low-smoke flame-retardant polyolefin by crosslinked with silicane, and linear molecular structure is changed into
Solid netted molecular structure can insulate, and high temperature resistant, have the characteristics of not prolonging combustion and will not producing hydrogen halide, not only improve
Electric property, physical property, mechanical performance, moreover it is possible to play very strong waterproof action, it is most important that burning will not produce
Poisonous gas, secondary injury will not be produced to human body；Fire proofing material uses ceramic halogen-free and low-smoke flame-retardant polyolefin material, in flame
Hard ceramic-like duricrust can be generated under calcination or hot conditions, duricrust is not melted, not dripped, can water resistant spray, not only can be with
Waterproof, and there is extraordinary heat-insulated fire insulation effect, it can ensure electricity in the case of spray water leaching when under fire condition or putting out a fire
Power and information control it is unimpeded, strive for valuable time for personnel escape and fire-fighting and rescue.Cable outer layer is hindered using low smoke, zero halogen
Polyolefin jacket material is fired, the protective cover material has the characteristics such as low cigarette, Halogen, fire-retardant low toxicity.

Description of reference numerals：Cable outer layer 1, inner core 2, fire proofing material 3, insulating barrier 21, flame retardant coating 22, wire core 23.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and specifically
Embodiment, the utility model is further elaborated.It should be appreciated that embodiment described herein is only used
To explain the utility model, it is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of flexible environment friendly type low-pressure fireproof cable, including cable outer layer 1 and inner core 2, outside cable
Inner core 2 is wrapped in interior by layer 1, it is characterised in that：The inner core 2 is from outside to inside successively by insulating barrier 21, flame retardant coating 22 and electric wire
Core 23 forms；The wire core 23 is well-regulated by some diameter identical copper wires, by concentric type, and successive layers time according to
What different direction process formed；Space between the cable outer layer 1 and insulating barrier 21 extrudes filling by fire proofing material 3.
Further, the flame retardant coating 22 is the overlapping wrapped composition of fluorine gold synthetic mica tape.
Further, the insulating barrier 21 is to extrude silane type halogen-free and low-smoke flame-retardant polyolefin.
Further, the insulating barrier 21 is handled by crosslinked with silicane, and linear molecular structure is changed into solid netted point
Minor structure.
Further, the fire proofing material 3 uses ceramic halogen-free and low-smoke flame-retardant polyolefin material.
Yet further, the cable outer layer 1 is halogen-free and low-smoke flame-retardant polyolefin material.
