Abstract
The present invention provides a kind of twin-core side's cable, which is rectangular configuration, and including two rectangular cable cores being twisted in rectangle oversheath and oversheath, the cable core includes one to three core in square insulating layer and insulating layer.Core and cable core of the present invention directly drag, and save packing material and band, reduce the twisted waste of material for increasing length, alleviate weight.
Description
Technical field
The present invention relates to electric wire field, specifically a kind of twin-core side's cable.
Background technology
Quad in the prior art, usual structure are that the round core for being extruded with insulation by two is twisted or two
Root segment conductor-core is twisted.Quad core include the identical four grade cores of two cross-sectional area of conductor or three cross-sectional area of conductor it is big, one
The small 3+1 cores of cross-sectional area of conductor.Two round cores are twisted particularly two 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 thus and be twisted together, and being twisted, and be squeezed again after twisted or stranding
Jacket.This structure quad, not only cable core stability is poor, but also material utilization amount is big, also adds cable weight and cost.
Such as using two twisted segment conductor-core structures, 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 be susceptible to phenomena such as in uneven thickness, insulating layer splits；Its
Secondary, either which kind of is twisted the quad of form, lay configuration so that practical core length increases, waste of materials, increase weight
Amount, cable cost increase；Again, this structure also so that the outside diameter of cable is larger, and especially big specification cable, big outer diameter not only increases
Manufacture, transport difficult are added, and it is big to occupy laying space.Besides, the quad 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 two 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.
Invention content
The present invention provides a kind of twin-core side's cable, core and cable core directly drag, section to solve problem of the prior art
Packing material and band have been saved, has reduced the twisted waste of material for increasing length, alleviates weight.
The cable is rectangular configuration, described including two rectangular cable cores being twisted in rectangle oversheath and oversheath
Cable core includes several cores in square insulating layer and insulating layer.
It is further improved, the core is one to three.
Advantageous effect of the present invention is：
1st, core and cable core directly drag, and save packing material and band, reduce the twisted waste of material for increasing length, mitigate
Weight.
2nd, it will not wind, it is easy to be identified between cable, and working service is convenient.
3rd, 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 with
It plays a very good protection to phase cable core, effectively mitigates and damaged by external force, and may also function as shielding action, effectively reduced
The electromagnetic interference and extraneous electromagnetic of electrical equipment around are interfered.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Structure of the present invention is as shown in Figure 1, the cable is rectangular configuration, including what is be twisted in rectangle oversheath and oversheath
Two rectangular cable cores, the cable core include several cores in square insulating layer and insulating layer.
It is further improved, the core is one to three.
The core and cable core of the present invention directly drags, and saves packing material and band, reduces the twisted material for increasing length
Material waste, alleviates weight；And it will not be wound between core and cable core, it is easy to be identified between cable, and working service is convenient.It holds
The phase core of load power transmission is located at innermost layer, can not only play the role of it is similar steel wire armoured, can be to phase cable core
To good protective effect, effectively mitigate and damaged by external force, and may also function as shielding action, effectively reduce to electrical around
Electromagnetic interference and the extraneous electromagnetic interference of equipment.
There are many concrete application approach of the present invention, and the above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, without departing from the principle of the present invention, several improvement can also be made, this
A little improve also should be regarded as protection scope of the present invention.
