Abstract
The utility model discloses novel flexible fireproof cables, belong to field of cable technology.Including several conductors, the outer extruded insulation layer of conductor constitutes insulated wire cores, around galvanized steel strip composition armor of double-baging after insulated wire cores twisted synthesizing cable, fire-proof mud is filled between insulating layer and armor, armor is externally provided with oxygen barrier layer, oversheath is extruded with outside oxygen barrier layer.The utility model fireproof cable structure novel, flameproof effect is good, and the outer wall of insulating layer is wound with armor, to increase the mechanical strength of cable, improves erosion prevention, while can also extend the service life of cable；The outer wall of armor is equipped with magnesia oxygen barrier layer, and when the outer layer of cable is ignited, magnesia oxygen barrier layer is not melted non-ignitable hard shell by thermosetting, plays the role of cooling and isolation, and fire spreading is avoided to cause more huge economic loss；Fire-proof mud is filled between insulating layer and armor, fire-proof mud plays fire-retardant and oxygen-impermeable effect, avoids fire spreading.
Description
Technical field
The utility model relates to field of cable technology, specifically, more particularly to novel flexible fireproof cable.
Background technique
Currently, to be widely used in skyscraper, subway, power plant, nuclear power station, hospital, airport lamp etc. important for fireproof cable
Department and public place, when a fire, fireproof cable can guarantee communication, power circuit it is unimpeded, be life, property
Rescue try to gain time precious to one, make significant contribution to reduce casualties and property loss.
In recent years, in the electric system fire incident in global range, lead to electric system since power cable catches fire
The ratio of power failure is on the rise.Therefore there are a large amount of electrical equipments and intensive laying a large amount of in power plant, substation etc.
The incidence of electric system fire incident is reduced in the place of cable using fireproof cable, to guarantee the uninterrupted of important circuit
Power supply, the fire resistance property of traditional fireproof cable is limited, and when ambient temperature is very high, cable can be still ignited, once
It is ignited, burning can not be limited in subrange by traditional fireproof cable, cause the intensity of a fire to spread, and then burn very much
Power equipment causes great economic loss.
Summary of the invention
To solve the above-mentioned problems, the utility model discloses a kind of novel flexible fireproof cables.
The utility model is achieved through the following technical solutions:
A kind of novel flexible fireproof cable, the cable include several conductors, and the outer extruded insulation layer of the conductor constitutes exhausted
Edge core, around galvanized steel strip composition armor, the insulating layer and the armouring of double-baging after the insulated wire cores twisted synthesizing cable
Fire-proof mud is filled between layer, the armor is externally provided with oxygen barrier layer, oversheath is extruded with outside the oxygen barrier layer.
The insulating layer is extruded by heat curing type polyolefine material.
The oxygen barrier layer is magnesia oxygen barrier layer.
The oversheath is that thermoplastics type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
Compared with prior art, the utility model has the beneficial effects that
The utility model fireproof cable structure novel, flameproof effect is good, and the outer wall of insulating layer is wound with armor, to increase
The mechanical strength of cable improves erosion prevention, while can also extend the service life of cable；The outer wall of armor is equipped with oxygen
Change magnesium oxygen barrier layer, when the outer layer of cable is ignited, magnesia oxygen barrier layer is not melted non-ignitable hard shell by thermosetting, play cooling and
The effect of isolation avoids fire spreading from causing more huge economic loss；Fire-proof mud, fire prevention are filled between insulating layer and armor
Mud plays fire-retardant and oxygen-impermeable effect, avoids fire spreading.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, conductor；2, insulating layer；3, fire-proof mud；4, armor；5, oxygen barrier layer；6, oversheath.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
A kind of novel flexible fireproof cable, the cable include several conductors 1, and the outer extruded insulation layer 2 of the conductor 1 is constituted
Insulated wire cores, around galvanized steel strip composition armor 4 of double-baging after the insulated wire cores twisted synthesizing cable, the insulating layer 2 with it is described
Fire-proof mud 3 is filled between armor 4, the armor 4 is externally provided with oxygen barrier layer 5, is extruded with oversheath 6 outside the oxygen barrier layer 5.
The insulating layer 2 is extruded by heat curing type polyolefine material.
The oxygen barrier layer 5 is magnesia oxygen barrier layer.
The oversheath 6 is that thermoplastics type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
As shown in Figure of description Fig. 1, a kind of novel flexible fireproof cable, cable includes several conductors 1, is squeezed outside conductor 1
Packet insulating layer 2 constitutes insulated wire cores, around galvanized steel strip composition armor 4 of double-baging after insulated wire cores twisted synthesizing cable, insulating layer 2 with
Fire-proof mud 3 is filled between armor 4, armor 4 is externally provided with oxygen barrier layer 5, oversheath 6, insulating layer 2 are extruded with outside oxygen barrier layer 5
It is extruded by heat curing type polyolefine material, oxygen barrier layer 5 is magnesia oxygen barrier layer, and oversheath 6 is thermoplastics type's LSOH anti-flaming
Polyolefin jacket.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
