Background technology
Five-core cable in the prior art, usual structure are that the round core for being extruded with insulation by five is twisted or four Root segment conductor-core is twisted with a round core.Five-core cable core includes five identical grade cores of five cross-sectional area of conductor, and three are led Body section is big, two cross-sectional area of conductor are small " three big two is small " core or four cross-sectional area of conductor are big, a cross-sectional area of conductor is small, and " four is big by one It is small " core.Five round cores are twisted particularly five unequal section circle cores and are twisted, and core gap is larger, not only so that electricity Cable roundness is poor, and easily loose and core easily channels bit during extruding and constructing etc., is usually added into thus Packing material is twisted together, and it is twisted when outer layer need to be tightened with band, be twisted or stranding after extrude sheath again.This structure five Core cable, not only cable core stability is poor, but also material utilization amount is big, also adds cable weight and cost.It is such as twisted using five Segment conductor-core structure, although cable core stability improves, core is processed into sector structure, processes relatively round core complexity, needs stringent Segment angle and fan-shaped height are controlled, and is susceptible to phenomena such as in uneven thickness, insulating layer splits；Secondly, either which kind of The five-core cable of twisted form, lay configuration so that practical core length increases, and waste of materials, increase weight, cable cost increase Greatly；Again, this structure also so that the outside diameter of cable is larger, especially big specification cable, and big outer diameter not only increases manufacture, transport Difficulty, and it is big to occupy laying space.Besides, the five-core cable electromagnetic interference of usual structure is larger.
The prior art circular configuration outside diameter of cable is big, is laid in wire casing, especially needs multi-cable while overlapping is applied If when, it occupies laying space still very greatly, use is limited in small space；Secondly, more round cables lay peace together It during dress, is easily wound between cable, and identifies difficult, working service trouble；Again, the identification of round cable core is difficult, especially It is five cross-section conductors, every core is needed to be identified；When besides, using round cable, due to it structurally Feature, the torsional moment that make whole cable are zero to be more difficult to, many occasions also need to move repeatedly using cable, be bent or Vertical to use, the torsion and installation that when torsion and manufacture of cable itself adds do not pay attention to increased torsion, especially vertical In use, cable lower superposition bears to discharge the twisting resistance transmitted above, therefore twisting resistance is maximum, therefore after the several months is used Can be distorted deformation, bulge, broken skin, until fractureing core wire.These not only easily cause accident, and cable short circuit or damage is caused to set It is standby；And cause cable reduced service life.Therefore still there is worth improved place.
In the prior art, there is the structure using flat cable, although can move repeatedly, be bent or vertically use, Five cores are arranged in parallel simultaneously, increase the length of cable, and structure is not compact；And existing cable fire-proof poor performance, heat dissipation Poor performance causes cable easily to generate heat spontaneous combustion.
Invention content
To overcome shortcoming of the existing technology, providing one kind can move repeatedly, is bent, vertically use the present invention, Compact-sized, outer diameter is small, easy to process and facilitate that construction, fire protecting performance be good, five cores composite fire-proof flat cable of perfect heat-dissipating.
For solution more than technical problem, a kind of five cores composite fire-proof flat cable of the present invention, which is flat knot Structure, cable center are equipped with three insulated wire cores directly dragged side by side, and several wire cores of laid out in parallel half-turn are led outside insulated wire cores Body and the neutral core of several of half-turn, ground wire core conductor and ceramic silicon rubber flame-retardant band wrapped outside neutral core, ceramic silicon rubber Mineral metal oversheath is extruded outside inhibiting tape, slot is provided in mineral metal oversheath, the filling heat absorption cotton in slot.
By aluminium alloy conductor and outside aluminium alloy conductor, ceramic silicon rubber flame-retardant band is formed the insulated wire cores.
The neutral core is by aluminium conductor and is extruded in steel band shielded layer outside aluminium conductor and forms.
Ground wire core conductor gap arrangement equidistant with neutral core is covered in the side of insulated wire cores periphery, two Person's quantity is identical.
The ground wire core conductor and the diameter of neutral core and the diameter phase of the copper monofilament of composition ground wire core conductor Together.
Advantageous effect of the present invention is：
Compared with prior art, five core flat cables of the invention, insulated wire cores, neutral core, wire core directly drag, save and fill out Material and band are filled, reduces the twisted waste of material for increasing length, alleviates weight；Squashed structure can move repeatedly, is curved Song or vertical use；As long as identify any one phase core, you can to differentiate whole cores；It will not wind, between cable Identification is easy, and working service is convenient；Flat, height is more round low, and wire core is divided into several independent conductors, into flat simultaneously Row are arranged in outside two phase cores arranged side by side, and laid out in parallel is short simultaneously compared with five cores for length, reduces laying space, easy for construction； Wire core flat laid out in parallel makes the insulated wire cores for undertaking power transmission be located at innermost layer, no outside three phase cores arranged side by side It can only play the role of similar steel wire armoured, can play a very good protection to phase cable core, effectively mitigate by external force Damage, and shielding action is may also function as, it effectively reduces and the electromagnetic interference and extraneous electromagnetic of electrical equipment around is done It disturbs；Add the structure of mineral metal sheath using ceramic silicon rubber flame-retardant band, substantially increase whole fire protecting performance, during burning not Any pernicious gas is generated, when fire occurs, the sustainable power supply of metal sheath inorganic mineral insulation cable,（Bear 950- 1000 DEG C of high temperature, 3 hours or more）, and water leaching when can bear fire-fighting relief and object is come off to gold in building during fire Belong to the mechanical shock of sheath inorganic mineral insulation cable, evacuation and fire rescue for crowd provide great guarantee；In mineral Slot is provided in metallic jacket, the filling heat absorption cotton in slot so that cable has good heat dissipation performance, will not occur certainly Fire phenomenon.
