Abstract
The utility model discloses a pottery insulated cable, including the cable inner core, the cable inner core by interior outside to in proper order the parcel have insulating layer, flame retardant coating and shielding layer, the equipartition has a plurality of inner sheath around the surface of shielding layer, the peripheral parcel of a plurality of inner sheath has armoured protection layer and oversheath, it has foam inflation fire extinguishing agent to pour into into in the inner sheath, it has inorganic fire -resistant inflation layer to pack between inner sheath and the armoured protection layer, the flame retardant coating adopts pottery silicon rubber materials layer, this structure by pottery silicon rubber materials layer as the flame retardant coating, protection of cables's that can be fine electric property, overall structure improves cable corrosion resistance and intensity, stability height to combine the inside material of putting out a fire, effective phenomenon of glowing of guaring against.
Description
Technical field
This utility model relates to technical field of electric wires and cables, specifically a kind of ceramic insulated cable.
Background technology
Most of the used insulating barrier of existing cable, restrictive coating mostly uses the insulant of Halogen.Cable is by the carrier that electric power transmission is the most frequently used, cable is in actual use, owing to the conductor part of cable exists resistance, easily accumulated heat, when accumulation of heat to a certain extent after, easily causing fire, fireproofing of cable technology increasingly causes the concern of people, and becomes an important development direction of line cable industry.
Utility model content
The purpose of this utility model is to provide a kind of ceramic insulated cable, poor with the fire resistance solving to propose in above-mentioned background technology, the problem of stability difference.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of ceramic insulated cable; including cable inner core; described cable inner core is enclosed with insulating barrier, flame retardant coating and screen layer the most successively; the external surface peripheral of described screen layer is evenly equipped with several inner sheaths; several inner sheath peripheries described are enclosed with armored protective layer and oversheath; it is injected with Foam Expansion extinguishing chemical in described inner sheath, between described inner sheath and armored protective layer, is filled with inorganic refractory expanding layer.
Preferably, described flame retardant coating uses Ceramic silicon rubber material layer.
Preferably, described armored protective layer uses polyester belt braiding insulated cladding.
Preferably, described inner sheath uses refractory fibre braided material to make.
Compared with prior art; the beneficial effects of the utility model are: when cable inner core overheated and after the screen layer that ignites; if the inner sheath contacted with screen layer is ignited network interface equally, then its interior fire foam overflows, and will play extinguishing effect; fire spread can also be stoped; meanwhile, the inorganic refractory expanding material heat filled in inner sheath and armored protective layer internal clearance expands, and can be pressed further by inner space; make internal without combustion medium, thus prevent fire spread.Additionally by Ceramic silicon rubber material layer as flame retardant coating, can well protect the electric property of cable, overall structure improves cable corrosion resistance and intensity, and stability is high.
Accompanying drawing explanation
Fig. 1 is structural section schematic diagram of the present utility model.
In figure: 1-cable inner core, 2-insulating barrier, 3-flame retardant coating, 4-screen layer, 5-inner sheath, 6-inorganic refractory expanding layer, 7-armored protective layer, 8-oversheath.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.nullRefer to shown in Fig. 1，A kind of ceramic insulated cable，Including cable inner core 1，Described cable inner core 1 is enclosed with insulating barrier 2 the most successively、Flame retardant coating 3 and screen layer 4，The external surface peripheral of described screen layer 4 is evenly equipped with several inner sheaths 5，Several inner sheath 5 peripheries described are enclosed with armored protective layer 7 and oversheath 8，It is injected with Foam Expansion extinguishing chemical in described inner sheath 5，Inner sheath 5 uses refractory fibre braided material to make，When the temperature of cable inner core 1 is increased to the burning-point of screen layer 4，Screen layer 4 ignites，So that the Foam Expansion extinguishing chemical in inner sheath 5 spills from braiding network interface，Play the effect of fire extinguishing，Additionally with Ceramic silicon rubber material layer, it is effectively protected the electric property of cable inner core 1 to flame retardant coating 3，Thus do not affected by outside phenomenon of glowing，And between inner sheath 5 and armored protective layer 7, it is filled with inorganic refractory expanding layer 6.Its heat expands, and is pressed further by inner space, so that burning area reduces, the phenomenon that prevents from glowing spreads.Armored protective layer 7 uses polyester belt to weave insulated cladding, can effectively meet the contracting strength of cable.It customizes model in production system is CTT-GANR, in order to manufacture Planning preparation, improves production efficiency.
Overall structure as flame retardant coating, can well be protected the electric property of cable by Ceramic silicon rubber material layer, and overall structure improves cable corrosion resistance and intensity, and stability is high, and connecting inner fire extinguishing material, effectively takes precautions against phenomenon of glowing and produces.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
