Row Development and Production sell mineral insulated cable, product agent structure by sub-thread conductor, powdered mineral insulation, smooth surface copper sheath, gather
Vinyl chloride or polyethylene outer sheath, have the following disadvantages：
1st, cable conductor is single strand configuration, and flexibility is poor.
2nd, cable insulation material is powdered, processing difficulties, length limited system.
3rd, cable copper sheath is smooth surface structure, and bending property is poor.
4th, protective coverings of cable is polyvinyl chloride or polythene material, and Safety and Environmental Protection is poor.
With the continuous intensive development in city, ground space becomes more and more narrower, therefore is selected in the city of modernization
Selecting construction large-scale tall buildings becomes a kind of mainstream development trend.Mineral insulated cable is used as the main anti-of large-scale tall buildings
Can fiery type equipment for power transmission and distribution, ensure that long-term safety reliable power supply is particularly important after its mounting and installation.Current enterprise
The mineral insulated cable structure and material of production and sales is simple, and comprehensive usability and Safety and Environmental Protection are poor, there is larger peace
Full hidden danger.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of skyscraper mineral insulated cable, can solve synthesis
The problem of usability and Safety and Environmental Protection difference, comprehensive performance is superior, and safety and environmental protection is safe and reliable to operation.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of skyscraper mineral insulation electricity
Cable, including by the cable core that at least an insulated wire cores are constituted,
Insulated wire cores are made up of the stranded conductor of multiply copper monofilament and the wrapped inner insulating layer outside conductor, inner insulating layer
By wrapped mica belt and LSOH anti-flaming belt outside conductor is constituted successively from inside to outside；
The ceramic polyolefin filling set outside insulated wire cores and insulated wire cores and external insulation layer composition cable core, ceramic polyene
Hydrocarbon is filled and external insulation layer is the integral structure formed by ceramic polyolefin packed layer and ceramic polyolefin external insulation layer；
Metal sheath layer and external sheath layer are disposed with outside cable core from the inside to the outside.
The quantity of insulated wire cores is three.
Metal sheath layer is the vertical copper strip layer being wrapped in outside cable core.
External sheath layer is halogen-free and low-smoke flame-retardant polyolefin external sheath layer.
The skyscraper mineral insulated cable that the present invention is provided, has the beneficial effect that：
1st, conductor is formed by multiply copper monofilament is stranded, possesses good flexibility.
2nd, inner insulating layer uses lapping structure, and by mica tape and LSOH anti-flaming band is wrapped forms, feasibility is good, has
Insulating properties and flame-retardant performance.
3rd, filling and external insulation layer are filled and coated using extrusion structure by ceramic polyolefin, compact conformation, with exhausted
Edge performance and fire resistance.
4th, metal sheath layer uses vertical pack arrangement, is formed by the vertical bag of copper strips and welded and bundle line, and good bending property has
Mechanical protection and gear fire action.
5th, external sheath layer is coated, with LSOH anti-flaming performance using extrusion structure by halogen-free low-smoke flame retardant material.
6th, detected by the present invention, as a result show that properties meet design requirement.With existing mineral insulation
Cable is compared, and structure is novel, and material is advanced, and comprehensive performance is superior；Fire protecting performance of the present invention is superior, with soft, bending
The characteristics such as performance is good, low-smoke non-halogen flame-retardant；Can lay and be used in skyscraper, comprehensive performance is superior, safety and environmental protection, transport
Row is more safe and reliable.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is schematic structural view of the invention.
Specific embodiment
In such as Fig. 1, a kind of skyscraper mineral insulated cable, including the cable core being made up of three insulated wire cores,
Insulated wire cores are made up of the stranded conductor 1 of multiply copper monofilament and the wrapped inner insulating layer outside conductor 1, interior insulation
Layer is by wrapped two-layer calcining mica belt 2 and LSOH anti-flaming belt 3 outside conductor 1 is constituted successively from inside to outside；
The ceramic polyolefin filling set outside insulated wire cores and insulated wire cores and the composition cable core of external insulation layer 4, ceramic gather
Alkene is filled and external insulation layer 4 is by the ceramic polyolefin packed layer and ceramic polyolefin external insulation layer using extrusion structure
The integral structure of formation；
Metal sheath layer 5 and external sheath layer 6 are disposed with outside cable core from the inside to the outside.
Metal sheath layer 5 is the vertical copper strip layer being wrapped in outside cable core.
External sheath layer 6 is halogen-free and low-smoke flame-retardant polyolefin external sheath layer.
Manufacturing process of the invention is as follows：
1st, conductor 1
Conductor 1 uses lay configuration, and many copper monofilament are stranded according to normally ordering mode, and outermost layer direction of lay is left-hand,
Stranded layering is carried out, and adjacent layer is twisted to opposite, it is ensured that the tight and Stability Analysis of Structures of conductor.
Conductive surface is bright and clean after conductor process, burr, sharp edge that insulated without greasy dirt, not damaged, without raised or fracture list
Line.
2nd, inner insulating layer
Inner insulating layer uses lapping structure, and in the outer hierarchical overlay of stranded conductor around calcining mica tape of double-baging, thickness is 0.18 milli
Rice, overlaps wrapped one layer of LSOH anti-flaming band outside two-layer calcining mica tape, and thickness is 0.20 millimeter.
Calcining Mica tape Duplication is 45%-50%, and the wrapped Duplication of LSOH anti-flaming band is 15%-20%, wrapped
Direction is left-hand, and surface must not have the phenomenons such as fold, lace, bottom pour ladle.
3rd, filling and external insulation layer 4
