Description
Technical field
The present invention relates to power cable field, specifically a kind of flexible mineral fire proof power cable.
Background technology
Power cable is the cable for transmitting and distributing electric energy, and power cable is usually used in Urban Underground power network, power station
Lead line, industrial and mining enterprises' in-line power and mistake river sea submarine transmission line.With the development of society, electrical equipment it is more and more and
Power load is big, and the safety of power supply is also particularly important, and still, because transmitting electric load is big, cable power transmission process is easy
Trigger fire, traditional fireproof cable is broadly divided into insulating stiff fireproof cable and inorganic mineral insulation cable, and former structure is hard
Degree is high, sets up installation difficulty height, entire length is shorter, is unfavorable for using；The latter easily makes moist, and damages internal cable core, wears cable
Overall flexibility it is poor.
The content of the invention
In order to avoid proposing a kind of flexible mineral fire proof power cable with solution above-mentioned technical problem, the present invention.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of flexible mineral fire proof power cable, including along the circumferential direction surround the several wire core of distribution, several wire
Filler is provided with the center of core distribution, the outside of several wire core is coated with band, inner sheath, metal armour successively from inside to outside
Dress, oversheath, between the core and band filled with glass tape it is overlapping made of fireprotection layer.
The core include be twisted copper conductor, be wrapped in outside copper conductor interior mineral insulation, be wrapped in mineral
External insulation layer outside insulating barrier.
As a further improvement on the present invention, the metal armouring is that aluminum alloy strip braiding forms.
As a further improvement on the present invention, the inner sheath and oversheath use LSOH anti-flaming ceramic polyene
Hydrocarbon material is made.
As a further improvement on the present invention, the interior mineral insulation is any of silicon rubber or polyolefin.
As a further improvement on the present invention, the external insulation layer is made up of LSOH anti-flaming material.
As a further improvement on the present invention, the core is five, the diameter of three cores in described five cores
Equal, the diameter of both threads core is equal and less than the diameter of three cores in addition.
As a further improvement on the present invention, the filler is PP inserts.
The beneficial effects of the invention are as follows：
The present invention is simple in construction, fireprotection layer and double-deck insulation system using densification parcel, can play excellent fire resisting
Fire protecting performance, internal cable core is avoided to make moist, it is ensured that cable safety, pernicious gas will not be produced during burning, there is good environmental protection
Property, the overall pliability of cable is high, is advantageous to install and use.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, below it is right
The present invention is expanded on further.
As shown in figure 1, a kind of flexible mineral fire proof power cable, including along the circumferential direction surround the several wire of distribution
Core, be provided with filler 4 at the center of several wire core distribution, the filler is PP inserts, the outside of several wire core by
It is coated with band 5, inner sheath 6, metal armouring 7, oversheath 8 successively from inside to outside, glass is filled between the core and band 5
Fireprotection layer 9 made of silk ribbon is overlapping.Glass tape does not only have the performance of fire protection flame retarding, moreover it is possible to certain moisture is absorbed, so as to rise
To the effect moistureproof to cable inside, protection interior metal conductor is destroyed, by the fireprotection layer of densification parcel, can played excellent
Fire resisting fire protecting performance, it is ensured that cable safety.
The core include be twisted copper conductor 1, be wrapped in outside copper conductor 1 interior mineral insulation 2, be wrapped in ore deposit
External insulation layer 3 outside thing insulating barrier 2, the interior mineral insulation 2 are any of silicon rubber or polyolefin, the external insulation
Layer 3 is made up of LSOH anti-flaming material.By the way of this double hyer insulation, greatly improve to the exhausted of internal metallic conductor
Edge,
The metal armouring 7 is that aluminum alloy strip braiding forms.In this way, the overall tension of cable can be strengthened to resist
Characteristic is pressed, improves the overall pliability of cable, convenience in transport and installation.
The inner sheath 6 and oversheath 8 are made of LSOH anti-flaming ceramic polyolefine material.Using this side
Method so that when cable catches fire, irritative gas will not be produced, be advantageously implemented site technology rescue.
The core is five, and the diameter of three cores is equal in described five cores, in addition the diameter of both threads core
Diameter that is equal and being less than three cores.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
For personnel it should be appreciated that the present invention is not limited to the above embodiments, that described in above-described embodiment and specification is the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
Improvement is both fallen within claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
