Description
Technical field
The present invention relates to electric wire field, three small cores of especially a kind of outside diameter block water flat cable.
Background technology
Three-core cable in the prior art, usual structure are that the circular core for being extruded with three insulation is twisted, or three
Root segment conductor-core is twisted.Three-core cable core include the identical third core of three cross-sectional area of conductor or two cross-sectional area of conductor it is big, one
The small 2+1 cores of cross-sectional area of conductor.Three circular cores are twisted particularly three unequal section circle cores and are twisted, core gap compared with
Greatly, not only so that cable roundness is poor, but also during extruding and construct etc. easily loosely, and core is easily altered
, outer layer need to be tightened with band when being usually added into packing material for this and be twisted together, and being twisted, and be squeezed again after twisted or stranding
Jacket.This structure three-core cable, not only cable core stability is poor, but also material utilization amount is big, also add cable weight and cost.
Three twisted segment conductor-core structures are such as used, although cable core stability improves, core is processed into sector structure, processes compared with round wires
Core is complicated, need to strictly control segment angle and fan-shaped height, and phenomena such as in uneven thickness, insulating layer splits easily occur；Its
Secondary, either which kind of is twisted the three-core cable of form, lay configuration so that actual core length increase, waste of materials, increase weight
Amount, cable cost increase；Again, this structure also make it that the outside diameter of cable is larger, and especially big specification cable, big outside diameter not only increases
Manufacture, transport difficult are added, and it is big to take laying space.Besides, the three-core cable electromagnetic interference of the usual structure of three cores compared with
Greatly.
Chinese patent ZL 200620073748.5 discloses a kind of three-core cable, using circular shape concentric structure, reduces electricity
Cable outside diameter, reduces the waste of material of twisted increase length, alleviates weight, not only reduce and account for deposited space, easy for construction, and
Cost is reduced, is also beneficial to reduce electric energy loss.But the outside diameter of cable of this structure is still very big, height is high, when online
Laid in groove, when especially needing multi-cable overlapping laying at the same time, take laying space still very greatly, limited in small space
Use is made；Secondly, more round cables together laying installation when, easily wind between cable, and identify difficult, working service
Trouble；Again, the identification of round cable core is difficult, and particularly three cross-section conductors are, it is necessary to which every core is identified；Again
Be exactly, during using round cable, due to its structurally the characteristics of, the torsional moment that to make whole cable is zero to be more difficult to, many fields
Conjunction is also needed to move repeatedly, bent using cable, or it is vertical use, the torsion that when torsion and manufacture of cable itself adds,
And installation does not pay attention to increased torsion, especially vertical in use, cable lower superposition bears to discharge what is transmitted above
Twisting resistance, therefore twisting resistance is maximum, thus the deformation that can be distorted after using the several months, bulge, broken skin, until the cored wire that fractures.This
Not only easily trigger accident a bit, cause cable short circuit or damage equipment；And cable service life is caused to shorten.Therefore still have worth
Improved place.
In the prior art, there is the structure using flat cable, although it can move repeatedly, bend, or vertical use,
Three cores 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 can be moved repeatedly, bends, vertically used,
Compact-sized, outside diameter is small, three core flat cables of easy to process and convenient construction.
To solve above technical problem, three small cores of a kind of outside diameter of the present invention block water flat cable, which is flat
Shape structure, cable center are equipped with two phase cores arranged side by side, and laid out in parallel one encloses some ground wire core conductors, ground outside phase core
Wrapped twining package tape outside cable core conductor, the outer extrude sheath of twining package tape.Ground wire core conductor peripheral hardware flat blocks water hose, ground wire core conductor and
The gap filling water blocking yarn that flat blocks water between hose, is provided with slot in sheath, the filling heat absorption cotton in slot.
By phase conductor and outside phase conductor, twining package tape is formed the phase core.
The phase conductor is twisted by some monofilament.
The equidistant gap arrangement of the ground wire core conductor is covered with phase core periphery, its diameter is with forming phase line
The filament diameter of conductor is identical.
The ground wire core conductor is solid naked round conductor or is the solid round conductor for extruding insulation.
Beneficial effect of the present invention is：
Compared with prior art, three small cores of outside diameter of the invention block water flat cable, and phase core, wire core are directly dragged, saved
Packing material and band, reduce the waste of material of twisted increase length, alleviate weight；Squashed structure, can move repeatedly,
Bending, or vertical use；As long as identify any one phase core, you can to differentiate whole cores；Will not wind, cable it
Between identify easy, working service is convenient；Flat, height is more circular low, and wire core is divided into some independent conductors, into flat
For laid out in parallel outside two phase cores arranged side by side, laid out in parallel is short at the same time compared with three cores for length, reduces laying space, construction party
Just；Wire core flat laid out in parallel makes the phase core for undertaking power transmission be located at innermost layer, no outside two 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, the electromagnetic interference to electrical equipment around is effectively reduced, and extraneous electromagnetic is done
Disturb.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
The present invention is further elaborated below in conjunction with the accompanying drawings：
