Description
Technical field
This utility model belongs to field of cables, particularly relates to a kind of compound insulation fireproof cable.
Background technology
Along with expanding economy and growth in the living standard, fire-fighting system is more and more higher to the security requirement of cable.Fireproof cable product in the market mainly divides two big classes, one class is magnesium oxide insulated copper sheath mineral insulated cable, the insulant of this type of cable be magnesia powder easily during installing and using the moisture absorption cause decreasing insulating, additionally this type of cable can not do multicore electric cable with large cross-section, production length is short, installation process center tap is many, is manufactured into mounting cost big.Another kind of is flexible mineral insulation cable, and this type of cable uses mica tape insulation wrinkle copper sheath structure, and flexibility is soft relative to magnesium oxide insulating cable, if but there is also copper sheath defective time, this type of cable is easily intake, and causes operation dangerous, lays difficulty.
Utility model content
The purpose of this utility model is to provide one and can produce continuously by long length, and mounting and installation is convenient, a kind of compound insulation fireproof cable of dependable performance.
To achieve these goals, this utility model is achieved through the following technical solutions: a kind of compound insulation fireproof cable, and it includes wire core and five layers of jacket layer of parcel core；Described five layers of jacket layer are core band, ceramic polyolefin separators, mica wrapping tape layer, aluminum alloy strip lock armo layer and restrictive coating successively；Described restrictive coating internal cladding aluminum alloy strip lock armo layer；Inside described aluminum alloy strip lock armo layer, mica wrapping tape layer is set；Ceramic polyolefin separators is extruded inside described mica wrapping tape layer；It is provided with core band inside described ceramic polyolefin separators；Described core band inner homogeneous extrudes three groups of wire cores；Described wire core includes copper conductor, mica tape insulating barrier, crosslinked polyetylene insulated layer；Described copper conductor outer wrap mica tape insulating barrier；The outside wrapped crosslinked polyetylene insulated layer of described mica tape insulating barrier;Gap between described core band and wire core is additionally provided with packed layer.
Described mica tape insulating barrier is that three stratus master tapes are put up wrapped, and rate of putting up is not less than 30%.
The described crosslinked polyetylene insulated composite insulation layer constituting cable together with mica tape insulating barrier.
Described packed layer is alkali-free glass fibre yarn.
Described restrictive coating is low-smoke halogen-free polyolefin material.
The beneficial effects of the utility model are in sum:
This utility model, by the redesign to the construction of cable, successfully solves fireproof cable and there are some problems in producing and installing and using, it is provided that one can produce by long length continuously, and mounting and installation is convenient, a kind of compound insulation fireproof cable of dependable performance.
Accompanying drawing explanation
Fig. 1 is this utility model cross-sectional structure schematic diagram.
Detailed description of the invention
As it is shown in figure 1, a kind of compound insulation fireproof cable, it includes wire core and five layers of jacket layer of parcel core；Described five layers of jacket layer are core band 5, ceramic polyolefin separators 6, mica wrapping tape layer 7, aluminum alloy strip lock armo layer 8 and restrictive coating 9 successively；Described restrictive coating 9 internal cladding aluminum alloy strip lock armo layer 8；Described aluminum alloy strip lock armo layer 8 is internal arranges mica wrapping tape layer 7；Described mica wrapping tape layer 7 is internal extrudes ceramic polyolefin separators 6；Described ceramic polyolefin separators 6 is internal is provided with core band 5；Described core band 5 inner homogeneous extrudes three groups of wire cores；Described wire core includes copper conductor 1, mica tape insulating barrier 2, crosslinked polyetylene insulated layer 3；Described copper conductor 1 outer wrap mica tape insulating barrier 2；The outside wrapped crosslinked polyetylene insulated layer 3 of described mica tape insulating barrier 2;Gap between described core band 5 and wire core is additionally provided with packed layer 4.
Described mica tape insulating barrier 2 is that three stratus master tapes are put up wrapped, and rate of putting up is not less than 30%.
Described crosslinked polyetylene insulated 3 constitute the composite insulation layer of cable together with mica tape insulating barrier 2.
Described packed layer 4 is alkali-free glass fibre yarn.
Described restrictive coating 9 is low-smoke halogen-free polyolefin material.
The mica tape insulating barrier 2 that this utility model cable uses is three layers of Mica tape, and every layer of Mica tape puts up rate not less than 30%.Mica tape insulating barrier 2 provides the insulating properties in certain time when cable fire, it is ensured that cable safe operation in case of fire.
The crosslinked polyetylene insulated layer 3 of this utility model cable is a kind of protection to mica tape insulating barrier 2, prevents mica tape insulating barrier 2 moisture absorption, under cable normal operation, by mica tape insulating barrier 2 and the insulating properties of crosslinked polyetylene insulated layer 3 shared cable.
The sealing coat ceramic polyolefin separators 6 of this utility model cable, during cable fire, in the case of this layer has flame, nonflame at 300-2000 DEG C, do not melt, do not drip, do not fall off, adamantine ceramic supporting body can be burnt till, good fire insulation, effect of heat insulation can be played, spray, shake after do not fall out.
Sealing coat is played the effect of tightening when cable fire by mica wrapping tape layer 7 of the present utility model, beneficially the ceramming process of sealing coat 6.
Aluminum alloy strip lock armo layer 8 of the present utility model plays the effect of gear fire when cable fire, the most in use plays a protective role cable core, prevents damaged by rats and Coptotermes formosanus Shtrari. moth erosion.
The above is this utility model embodiment, therefore all equivalence changes done according to structure, feature and the principle described in this utility model application range or modification, all it is included in this utility model patent claim.
