Abstract
The utility model discloses a kind of fireproof power cable, including cylindrical cable core, cable core includes three fan-shaped conductors, insulating barrier has been respectively coated by outside conductor, insulating barrier is coated with band, and band is filled with foam fire-fighting material with insulation interlayer, and cable core is coated by fireproof band, the space of cable core is filled by glass cord, and fireproof band is coated with external insulation layer；The power cable is after the single-phase heating of generation is on fire; foam fire-fighting material self-extinguishing, not only it is avoided that sprawling adjacent mutually on fire, and that the intensity of a fire can also be prevented; fireproof band can protect outermost insulating barrier to be burned out, even if therefore the cable still can normal use after single-phase fire extinguishing on fire.
Description
Technical field
Cable is the utility model is related to, more particularly to a kind of fireproof power cable.
Background technology
With social development by now, high buildings and large mansions are converged over the sky, and either office block or house is all concentrated
Many people and finance, and the setting of cable be exactly for every household power supply, but its often cluster laying in same cable passage
Interior, once fire occurs, flame will prolong combustion along cable and spread to other positions and other floors, expand the intensity of a fire, so as to
Cause heavy economic losses, the normal life of serious threat people and life security.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of fireproof power cable, can avoid the sprawling of the intensity of a fire, prevents
Only phase fault causes the bigger intensity of a fire.
The purpose of this utility model is achieved through the following technical solutions：
Fireproof power cable, including cylindrical cable core, the cable core include three fan-shaped conductors, distinguished outside the conductor
Insulating barrier is coated with, the insulating barrier is coated with band, and the band is filled with foam fire-fighting material with insulation interlayer, described
Cable core is coated by fireproof band, and the space of the cable core is filled by glass cord, and the fireproof band is coated with outer
Insulating barrier.
Further, the insulating barrier is wrapped inorganic mineral synthetic mica tape.
Further, the band is glass fiber tape.
Further, the fireproof band is Ceramic silicon rubber fireproof band.
The beneficial effects of the utility model are：
Fireproof power cable of the present utility model, after the single-phase heating of generation is on fire, foam fire-fighting material self-extinguishing, no
Sprawling adjacent mutually on fire, and that the intensity of a fire can also be prevented only is avoided that, fireproof band can protect outermost insulating barrier to be burnt
Ruin, even if therefore the cable still can normal use after single-phase fire extinguishing on fire.
Other advantages, target and feature of the present utility model will be explained in the following description to a certain extent
State, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or
Person can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be said by following
Bright book is realized and obtained.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with accompanying drawing to this practicality
It is new to be described in further detail, wherein：
Fig. 1 is the utility model structure diagram.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.It is it should be appreciated that it is preferred that real
Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.
As shown in figure 1, fireproof power cable, including cylindrical cable core, cable core includes three fan-shaped conductors 1, outside conductor
Insulating barrier 2 is respectively coated by, insulating barrier is coated with band 3, and band is filled with foam fire-fighting material 4, cable core with insulation interlayer
Coated by fireproof band 5, the space of cable core is filled by glass cord 6, and fireproof band is coated with external insulation layer 7.
Insulating barrier is wrapped inorganic mineral synthetic mica tape.Band is glass fiber tape.
Fireproof band is Ceramic silicon rubber fireproof band, its fireproof excellent performance, even more than its fire resisting
The limit remains to ablation and forms hard containment vessel, and containment vessel can prevent flame from further extending to Exterior cable, it is ensured that cable
Normal usage function, and the complete whole property of fire-resisting cable can be kept；In addition, it can also improve the insulation of fireproof power cable
Performance.
Fireproof power cable of the present utility model, after the single-phase heating of generation is on fire, foam fire-fighting material self-extinguishing, no
Sprawling adjacent mutually on fire, and that the intensity of a fire can also be prevented only is avoided that, fireproof band can protect outermost insulating barrier to be burnt
Ruin, even if therefore the cable still can normal use after single-phase fire extinguishing on fire.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, and without departing from the objective and scope of the technical program, it all should
Cover among right of the present utility model.
