Description
Technical field
The invention belongs to field of cables, particularly a kind of four core complex minerals fire prevention control flat cable.
Background technology
With the popularization of computer technology and the rapid development of information industry, Intellectual district becomes modern architecture
Development trend, by by the comprehensive wiring system that composite cable etc. forms the communication in intelligent construction, computer and each
Kind equipment and facility, include comprehensive wiring system under certain conditions, are interconnected to form complete supporting entirety, to realize
Highly intelligentized requirement.
Four core composite cables of the band control cable core of the prior art, usual structure is to be extruded with control cable core and four absolutely
The circular core of edge is twisted, or four segment conductor-cores are twisted and are twisted afterwards with control cable core.Quad core includes four conductors
Four identical grade cores of section or three 3+1 cores that cross-sectional area of conductor is big, a cross-sectional area of conductor is small.Either which kind of form is twisted,
Core gap is larger, not only so that cable roundness is poor, and also it is easily loose during extruding and construct etc., and core appearance
Easily channel bit, be usually added into packing material for this and be twisted together, and it is twisted when outer layer need to be tightened with band, be twisted or into
Extrude sheath again after cable.This structure band controls four core composite cables of cable core, and not only cable core stability is poor, but also material utilization amount
Greatly, cable weight and cost be also add.Four twisted segment conductor-core structures are such as used, although cable core stability improves, line
Core is processed into sector structure, processes relatively round core complexity, need to strictly control segment angle and fan-shaped height, and thickness easily occur
Phenomena such as uneven, insulating layer splits；Secondly, the band of either which kind of twisted form controls four core composite cables of cable core, twists
Close structure and cause actual core length increase, waste of materials, increase weight, cable cost increase；Again, this structure also causes electricity
Cable outside diameter is larger, especially big specification cable, and big outside diameter not only increases manufacture, transport difficult, and takes laying space
Greatly.Besides, the composite cable power wire core of usual structure is larger to the electromagnetic interference of control conductor.
Using circular shape concentric structure, the outside diameter of cable can be reduced, the waste of material of twisted increase length is reduced, alleviates weight
Amount, not only reduces and accounts for deposited space, easy for construction, and reduces cost, is also beneficial to reduce electric energy loss.But this structure
The outside diameter of cable is still very big, height is high, when being laid in wire casing, when especially needing multi-cable overlapping laying at the same time, account for
It is still very big with laying space, use is limited in small space；Secondly, more round cables together laying installation when, electricity
Easily wound between cable, and identify difficult, working service trouble；Again, the identification of round cable core is difficult, particularly four etc.
Segmental conductor is, it is necessary to which every core is identified；When besides, using round cable, due to its structurally the characteristics of, to make
The torsional moment of whole cable is zero to be more difficult to, and many occasions are also needed to move repeatedly, bent using cable, or it is vertical use,
The torsion added when the torsion and manufacture of cable itself, and installation do not pay attention to increased torsion, especially vertical in use, electricity
The superposition of cable lower end bears to discharge the twisting resistance transmitted above, therefore twisting resistance is maximum, therefore can be turned round after using the several months
Bent deformation, bulge, broken skin, up to the cored wire that fractures.These not only easily trigger accident, cause cable short circuit or damage equipment；And
Cable service life is caused to shorten.Therefore still there is worth improved place.
In the prior art, there is the structure using flat cable, although it can move repeatedly, bend, or vertical use,
Four cores and control cable conductor are arranged in parallel at the same time, add the length of cable, and structure is not compact.
The content of the invention
The present invention is to overcome shortcoming existing in the prior art, there is provided one kind at the same time can simultaneous transmission electric power and control letter
Number, compact-sized, outside diameter is small, and can move repeatedly, bend, vertically using, four cores of construction easy to process and convenient it is compound
Mineral fire prevention control flat cable.
A kind of four cores complex mineral fire prevention control flat cable disclosed by the invention, including the insulated core directly dragged side by side and control
Cable core processed；Three insulated wire cores are directly dragged at the insulated core center side by side, in three some of insulated wire cores periphery laid out in parallel
Ground wire core conductor, ground wire core conductor with extruding inorganic mineral metal inner sheath jointly outside three insulated wire cores；The control cable core
Inorganic mineral metal inner sheath is extruded after being twisted by some control conductors；Gap between insulated core and control cable core
Filled glass fiber silk, flat inorganic mineral metallic jacket is extruded outside insulated core and control cable core jointly.
Further improve, the insulated wire cores are twisted the copper conductor that forms by some copper monofilament and around copper conductor
Mineral insulation is formed.
Further improve, the diameter of the copper monofilament is identical with the diameter of gnd conductor.
Further improve, the control conductor is by aluminium alloy conductor and the mineral insulation being extruded in outside aluminium alloy conductor
Form.
Further improve, the gap filled glass fiber silk between the insulated wire cores and ground wire core conductor.
Further improve, the gap filling flameproof fabric between the control conductor.
Beneficial effects of the present invention：
The present invention can be and independent mutually with simultaneous transmission electric power and control signal；Insulated wire cores, wire core, control cable core are straight
Drag, save packing material and band, reduce the waste of material of twisted increase length, alleviate weight；Squashed structure, can be with
Move repeatedly, bend, or vertical use；Due to there is the presence of control cable core, without identifying phase core, wire core, you can with
Whole phase cores, wire core are differentiated, will not be wound, it is easy to be identified between cable, and working service is convenient；Flat, it is highly relatively round
Shape is low, and wire core is divided into some independent conductors, and into flat laid out in parallel outside three phase cores arranged side by side, width is compared with four
Laid out in parallel is short at the same time for core, reduces laying space, easy for construction.Wire core flat laid out in parallel is in three phase cores arranged side by side
Outside, the phase core for undertaking power transmission is located at innermost layer, can not only play the role of it is similar steel wire armoured, can be to phase line
Cable core plays a very good protection, and effectively mitigates and is damaged by external force, and may also function as shielding action, effectively reduces to control
The electromagnetic interference of cable core processed and surrounding electrical equipment, and extraneous electromagnetic interference；Using inside and outside mineral metal sheath, greatly improve
Overall fire protecting performance, when burning, do not produce any pernicious gas, when fire occurs, metal sheath inorganic mineral insulated electro
The sustainable power supply of cable,（Bear 950-1000 DEG C of high temperature, 3 it is small when more than）, and water leaching when fire-fighting is succoured can be born, and fire
When building in come off mechanical shock of the object to metal sheath inorganic mineral insulation cable, be evacuation and the fire rescue of crowd
There is provided and greatly ensure.
