Description
Technical field
It the utility model is related to flexible fire-proof cable, more particularly to a kind of anti-thermoelectricity of flexible inorganic available for vertical run
Power cable.
Background technology
Continuous development and needs due to safety devices and skyscraper, to the performance of fireproof cable, installation and using each
Aspect requirement is also constantly being improved, and the new construction of cable is used so as to occur this.Former common fireproof cable is metal shield
Inorganic matter fireproof cable is covered, production length is restricted, and in mounting and installation with special binding post and terminal box,
And highly professional installation cost it is high the defects of.And the common fireproof cable structure occurred in recent years is soft for the fireprotection layer of extrusion
State, it is not suitable for the vertical run requirement of skyscraper again.
Utility model content
The defects of in order to make up prior art, this utility model fireproof cable has high fire line, not by production length
Limitation, mounting and installation is convenient, is not required to dedicated terminals and terminal box, can be laid in any environment and occasion, more can be with vertical run.
The technical solution of the utility model is as follows：
A kind of flexible inorganic fire proof power cable for vertical run, it is characterised in that cable center is glass-silk rope,
The cable includes conductor, and wrapped mica tape insulating barrier is provided with outside conductor, is set outside the wrapped mica tape insulating barrier
There are PE color separation separation layers, be provided with fire-proof mud mixed layer outside glass-silk rope and PE color separations separation layer, mixed in the fire-proof mud
Close and be surrounded with ceramic combination flame retardant coating outside layer successively, extrude low smoke and zero halogen inner liner and steel wire armor layer.
Further, it is provided with outside the steel wire armor layer and extrudes low smoke and zero halogen sheath outside.
Further, the conductor is four.
Further, ceramic combination flame retardant coating can be Ceramic silicon rubber band.
Further, the fire-proof mud is magnesia mixture.
The beneficial effects of the utility model are that the construction of cable is simple, and laying is convenient.Both solved conventional metals sheath to prevent
Thermoelectricity cable production length limitation problem, solves the problems, such as that novel flexible fireproof cable is unable to vertical run again.And this cable
Dedicated terminals and terminal box are not required to, more reduce installation cost.Require that high place uses suitable for various fire protecting performances.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
As shown in figure 1, conductor 1, mica tape insulating barrier 2, PE color separations separation layer 3, fire-proof mud mixed layer 4, ceramic combine
Flame retardant coating 5, extrude low smoke and zero halogen inner liner 6, steel wire armor layer 7, extrude low smoke and zero halogen sheath 8, glass-silk rope 9 outside.
Embodiment
As shown in figure 1, the utility model is a kind of flexible inorganic fire proof power cable for vertical run, cable center
For glass-silk rope 9, center-filled uses circular flame retardant filler strip, in order to ensure the stabilization of the construction of cable and rounding property, as one
Individual support.The cable includes conductor 1, and wrapped mica tape insulating barrier 2 is provided with outside conductor 1, exhausted in the wrapped mica tape
The outside of edge layer 2 is provided with PE color separations separation layer 3, and fire-proof mud mixed layer 4 is provided with outside PE color separations separation layer 3, is mixed in fire-proof mud
Close and be surrounded with ceramic combination flame retardant coating 5 outside layer 4 successively, extrude low smoke and zero halogen inner liner 6 and steel wire armor layer 7.Low smoke and zero halogen
Inner liner 6 can be orange or other colors, ceramic low smoke and zero halogen inner sheath, can quickly consolidate when fire occurs
Change, incrustation, can slow down or avoid internal structure from burning away.Increase fire protecting performance.Substantially increased using steel wire armor layer 7
The tensile strength of cable, steel wire armor layer 7 are mainly endwise tensile strength when solving such a cable lifting, improve knot
The stability of structure.So as to improve cable life.
Further, the outside of steel wire armor layer 7 is provided with extrudes low smoke and zero halogen sheath 8 outside, outside ceramic low smoke and zero halogen
Sheath, it can quickly solidify when fire occurs, form a scab, can slow down or avoid internal structure from burning away.Increase fire prevention
Performance.
Further, the conductor 1 is four, and four conductors 1 are stirred around the glass-silk rope 9 of cable center and formed, and are
Ensure the stabilization and integrality of the construction of cable, as a support.
Further, ceramic combination flame retardant coating 5 can be Ceramic silicon rubber band, can further function as well
Fire-retardant, fire resisting, fire prevention, the effect of fire insulation.
Further, the fire-proof mud is magnesia mixture, and fire-proof mud can form ceramics material when meeting fire burning,
And be amenable to burn three hours at 1000 DEG C, cable energy normal operation.
The beneficial effects of the utility model are that the construction of cable is simple, and laying is convenient.Both solved conventional metals sheath to prevent
Thermoelectricity cable production length limitation problem, solves the problems, such as that novel flexible fireproof cable is unable to vertical run again.And this cable
Dedicated terminals and terminal box are not required to, more reduce installation cost.Require that high place uses suitable for various fire protecting performances.
Described above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of technical field
For personnel, on the premise of the utility model principle is not departed from, some improvement can also be made, these improvement also should be regarded as this
The protection domain of utility model.
