Description
Technical field
The present invention relates to fireproof cable technical field more particularly to a kind of flexible wrinkle copper sheath fireproof power cables.
Background technique
Building requires fire-retardant and fire-resisting cable comprehensively at current densely populated place, and the fire resistance of common fire-resisting cable is not
Foot, fire resistance is poor and mineral insulated cable lays the difficult and poor problem of bending property；Given this develop it is fire-retardant with it is resistance to
The flexible wrinkle copper sheath fireproof power cable of fiery function admirable be there is an urgent need to.
Summary of the invention
To solve technical problem present in background technique, the present invention proposes a kind of flexible wrinkle copper sheath fire resistant electric power electricity
Cable.
A kind of flexible wrinkle copper sheath fireproof power cable proposed by the present invention, including cable core, flame retardant filler, resistance to fire screen
Absciss layer and wrinkle copper sheath；The fire resisting separation layer overlapping is around the outside of the cable core；The wrinkle copper sheath is coated on
The outside of fire resisting separation layer；The cable core includes several electrified wires, and each electrified wire includes conductor and is coated on
Refractory insulating layer outside the conductor；Wherein flame retardant filler is filled in cable core gap；Wherein in the flame retardant filler
Several elastic insulated bands are embedded in, guarantee the intensity and curvature of cable by the elastic insulated band in flame retardant filler.
Preferably, the conductor using TR type soft copper wire stranding and is pressed into round conductor or sector conductor.
Preferably, the refractory insulating layer and fire resisting separation layer are all made of inorganic fire proof material, and flame is isolated and high temperature is used.
Preferably, the wrinkle copper sheath uses copper strips longitudinal wrap embossing, and copper strips connecting sewing closes up into copper using laser welding
Pipe, improves its bending property and tensile property.
Preferably, fire resisting separation layer using inorganic fire proof material be overlapped on cable core it is wrapped preferably, flame resistant filler
Cable core gap location is filled in using fire proofing.
Preferably, the conductor is twisted by stranded copper wire, and stranded copper wire is directly combined in regular twisted mode；It protects
The softness of cable is demonstrate,proved, and is also most stable of layout type, external force is difficult to change the layout of the combination between them, is twisted
Die mould guarantees that conductor gap is smaller afterwards, and conductor is compact.
The present invention uses inorganic mine by setting by the flexible wrinkle copper sheath fireproof power cable of above-mentioned optimization design
Object insulating refractory plays on isolation external flame and temperature action to conductor, conductor overheat fusing is prevented, when fire occurs
Protection internal core can continue transmit electric energy, guarantee cable have good high temperature resistant, fire-retardant and fire resistance, bending property,
Tensile property.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention
Fig. 2 is the structural schematic diagram of conducting wire in the present invention；
Wherein: 1- fire resisting separation layer, 2- wrinkle copper sheath, 3- electrified wire, 31- conductor, 32- refractory insulating layer, 5- elasticity are absolutely
Marginal zone.
Specific embodiment
As shown in Figs. 1-2, a kind of flexible wrinkle copper sheath fireproof power cable of the present embodiment, including cable core, fire-retardant fill out
Fill object 4, fire resisting separation layer 1 and wrinkle copper sheath 2；The overlapping of fire resisting separation layer 1 is around the outside of the cable core；The wrinkle
Line copper sheath 2 is coated on the outside of fire resisting separation layer 1；The cable core includes several electrified wires 3, each electrified wire
3 include conductor 31 and the refractory insulating layer 32 being coated on outside the conductor 31；Wherein flame retardant filler 4 is filled in cable core gap
Place；Wherein the flame retardant filler 4 is embedded in several elastic insulated bands 5；Guarantee cable rounding and enhances fire-retardant and fire resistance
Energy.
In a specific embodiment, the conductor 31 using TR type soft copper wire stranding and is pressed into round conductor.
The refractory insulating layer 32 and fire resisting separation layer 1 are all made of inorganic fire proof material；Guaranteeing cable electrical performance
Meanwhile copper conductor being protected not fuse because of high temperature in certain time in the case where burning, cause cable to power off.
The wrinkle copper sheath 2 uses copper strips longitudinal wrap embossing, and copper strips connecting sewing closes up into copper pipe using laser welding.
The beneficial effect of the present embodiment is: when fire occurs, protection internal core can continue to transmit electric energy, guarantee cable
With good high temperature resistant, fire-retardant and fire resistance, bending property, tensile property.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
