Description
Technical field
This utility model relates to field of cables, is specifically related to a kind of rare earth aluminium alloy fire-resisting cable.
Background technology
Along with the high speed development of industrial or agricultural and people are more and more higher for the pursuit of quality of life, society's demand to electric power
Increasing.The conductor of cable mostly is copper conductor and fine aluminium conductor at present.But all there is certain problem, copper in both conductors
The least of conductor is unfavorable for the tightness degree at terminal jointing, thus is not easy to compression relatively greatly, causes connect to stablize
Property is poor.In addition the cost of copper conductor is the highest.
In order to reduce cost, current commonly used fine aluminium conductor replaces copper conductor, but its elongation percentage of fine aluminium conductor is low,
Tensile strength is poor, and resistance to compression croop property, antiseptic property, pliability are poor, causes the less stable that cable long-term safety is run.
Utility model content
For defect present in prior art, the purpose of this utility model is provide a kind of low cost and can guarantee that electricity
The rare earth aluminium alloy fire-resisting cable that cable long-term safety is run.
For reaching object above, this utility model adopts the technical scheme that: a kind of rare earth aluminium alloy fire-resisting cable, bag
Include,
Many rare earth aluminum alloy conductors；
Flame retardant coating, it is around wrapping on described rare earth aluminum alloy conductor；
Insulating barrier, it is extruded on described flame retardant coating；
Sealing coat, it is around wrapping on described insulating barrier；
First implant, it is located between described insulating barrier and sealing coat；
Armor, it is located on described sealing coat；And
Flame retardant sheath layer, it is extruded on described armor superficies.
On the basis of technique scheme, described flame retardant coating is calcining mica tape.
On the basis of technique scheme, described calcining mica tape is two-layer.
On the basis of technique scheme, described insulating barrier is crosslinked polyethylene.
On the basis of technique scheme, described sealing coat is low smoke and zero halogen glass fiber band.
On the basis of technique scheme, described armor is high-flexibility aluminum alloy strip.
On the basis of technique scheme, described flame retardant sheath layer is low smoke halogen-free flame-retardant polyolefin.
On the basis of technique scheme, described rare earth aluminum alloy conductor is 3.
On the basis of technique scheme, between described insulating barrier, it is provided with the second implant.
On the basis of technique scheme, it is fine that described first implant and the second implant are low smoke and zero halogen glass fiber
Dimension.
Compared with prior art, the utility model has the advantage of:
Rare earth aluminium alloy fire-resisting cable in this utility model, its conductor material uses rare earth aluminium alloy, itself and employing copper
The cable of conductor is compared, and reduces the cost of cable；Compared with the cable using fine aluminium conductor, both maintained the excellent of fine aluminium conductor
The opposite sex can, the elongation percentage the most thoroughly solving fine aluminium conductor is low, tensile strength is poor, resistance to compression croop property, antiseptic property, pliability
The problem of difference etc., it is ensured that the stability that cable long-term safety is run.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model middle rare earth aluminum alloy fire-resistant cable.
In figure: 1-rare earth aluminum alloy conductor, 2-flame retardant coating, 3-insulating barrier, 4-sealing coat, 5-the first implant, 6-armouring
Layer, 7-flame retardant sheath layer, 8-the second implant.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Shown in Figure 1, this utility model provides a kind of rare earth aluminium alloy fire-resisting cable, including rare earth aluminum alloy conductor 1,
Flame retardant coating 2, insulating barrier 3, sealing coat 4, the first implant 5, armor 6, flame retardant sheath layer 7, the second implant 8.
The quantity of rare earth aluminum alloy conductor 1 can the most rationally be arranged, this utility model middle rare earth aluminium alloy conductor 1
Quantity be 3, with use copper conductor cable compared with, reduce the cost of cable.Compared with the cable using fine aluminium conductor,
Both having maintained the excellent properties of fine aluminium conductor, the elongation percentage the most thoroughly solving fine aluminium conductor is low, tensile strength is poor, resistance to compression creep
The problem of performance, antiseptic property, pliability difference etc., it is ensured that the stability that cable long-term safety is run.
Flame retardant coating 2 is around wrapping on rare earth aluminum alloy conductor 1, and its material used is calcining mica tape, in this utility model
Flame retardant coating 2 include that two-layer calcines mica tape, the calcining temperature resistant grade of mica tape, flexibility is more superior compared with conventional cloud master tape,
Especially properties is more stable, and fire-resistant effect is more preferable.
Insulating barrier 3 is extruded on flame retardant coating 2, and its material used is crosslinked polyethylene, and crosslinked polyethylene maintains poly-second
Alkene original good insulation characteristic, and insulation resistance increases further, insulation effect is more preferable.
Sealing coat 4 is wrapped on the insulating layer 3, and its material used is low smoke and zero halogen glass fiber band.
First implant 5 is filled between insulating barrier 3 and sealing coat 4, and the second implant 8 is filled between insulating barrier 3, the
The material that one implant 5 and the second implant 8 use is low smoke and zero halogen glass fiber.
Armor 6 is located on sealing coat 4, and it is by high-flexibility aluminum alloy strip automatic interlock armouring.
Flame retardant sheath layer 7 is extruded on armor 6, and its material used is low smoke halogen-free flame-retardant polyolefin.
This utility model is not only limited to above-mentioned preferred forms, and anyone can obtain under enlightenment of the present utility model
Go out other various forms of products, no matter but in its shape or structure, make any change, every have and this utility model phase
Same or akin technical scheme, all within its protection domain.
