Abstract
The invention discloses a multicore rubber jacketed flexible cable for movement. The cable comprises a cable core, wherein a belting layer is wrapped outside the cable core in a surrounding manner; an internal sheath is wrapped outside the belting layer in an extrusion manner; a braid layer is weaved outside the internal sheath; an external sheath is wrapped outside the outermost layer in an extrusion manner; the cable core is formed by twisting a hollow-core tube in the center of the cable core and multiple insulating cable cores wrapped around the hollow-core tube in an extrusion manner; the hollow-core tube adopts a tubular TPE insulating and aramid fiber yarn straight pulling structure. According to the invention, the center of the cable adopts aramid fiber yarn straight pulling PTE insulating hollow-core tube to enable the cable to be suitable for the service environment with higher requirements, so that the tensile strength, the compression resistance, the torsion resistance and other mechanical stress of the cable can be effectively improved, and the multicore rubber jacketed flexible cable is suitable for frequent movement in the wild and on a construction site.
Description
?
Technical field
The invention belongs to pre-branched cable field, be specifically related to a kind of multicore and move and use rubber sleeve flexible cable.
Background technology
Plastic-sheathed Cable is widely used in various electric equipments, motor machine, and the portable power supply of electrical device and utensil can use simultaneously under indoor or outdoor environment condition.Product structure is divided into light-duty, medium-sized and heavy three classes according to the suffered mechanical external force of cable.General light type cab-tyre cable is used in household appliance, small-sized electric equipment; Medium-sized Plastic-sheathed Cable is widely used in industrial or agricultural electrification; Heavy cable is generally used for temporary construction etc. on harbour machinery, large-scale waterpower drainage and irrigation station and building site and can bears the occasion of larger mechanical external force effect.But common rubber cable is mobile bending easily outer drum, the disconnected core of having protected for a long time.Particularly building site or field cable, protect outward and insulation is squeezed or other external effect of stress under very easily insulating sleeve break and the phenomenon such as puncture, cause useful life short when serious whole cable the phenomenon such as scrap.Affect the normal operation of equipment and have in various degree potential safety hazard.The reason that produces above defect is as follows:
1, broken string punch-through
In use, because of the long-term frequent bending back twist effect of moving or being returned line states by tortuous state shift of cable, conductor and insulation all can be elongated for equipment; And after stress is cancelled, insulation is because the rebound effect of self can reduce, and conductor can not reduce and form length difference, in the course of time, causes conductor to bloat; Produce broken string or punch-through.
2, the damaged punch-through of insulating sleeve skin
Because of the long-time field of cable or building site use, cable can be because of exterior mechanical stress, the aging impact of exposing to the weather, (as the transport vehicle in building site rolls, stone clashes into, etc. the reason of a series of external power) causes that cable insulation punctures, sheath breaks, and an even whole cable is scrapped.Cable moving is bending to be risen and can make after drum drum locate the phenomenon such as first break easy to wear.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of resistance to compression is provided, resistance toly turns round, the disconnected multicore of anti-tension moves with rubber sleeve flexible cable, is adapted at field, building site, frequent mobile using.
A kind of multicore of the present invention moves with rubber sleeve flexible cable, comprises cable core, the outer wrapped belting layer of its cable core, and belting layer extrudes inner sheath outward, and inner sheath weaves braid outward, and outermost layer extrudes oversheath; Described cable core is by being positioned at the hollow pipe at its center and being extruded in stranded the forming of many insulated wire cores of hollow pipe surrounding; Its hollow pipe adopts tubulose TPE insulation to add aramid fiber yarn and directly drags structure.
Further improve, described cable core gap is provided with rubber bar and fills.
Further improve, described insulated wire cores is formed by conductor and the insulating barrier that is extruded in outside conductor.
Further improve, described conductor adds aramid fiber tow by steel wire and closes and form.
Further improve, described belting layer adopts polypropylene material.
Further improve, described braid adopts Polyamide Yarns and aramid fiber yarn combined knitting to form.
Further improve, described inner sheath and oversheath adopt TPE material.
Beneficial effect of the present invention is:
Compared with prior art, advantage of the present invention is: 1) conductor center adds aramid fiber yarn, prevents that conductor is elongated in BENDING PROCESS, can not produce insulated wire cores and bloat, and therefore and first conductor can not rupture, and increases the service life; 2) placed and special directly dragged the hollow pipe of PTE insulation with aramid fiber yarn in cable center when stranding, greatly increased the external mechanical stress such as tension, antitorque particularly resistance to compression of this line; 3) be wound around CPP band outward at stranding and replace nonwoven fabrics, make it flexibility in moving process better.4) Polyamide Yarns aramid fiber yarn combined knitting is not easily broken in moving process, protects and insulate to strengthen the mechanical performance of each side in protection.5) PTE insulation and sheath replace common rubber material, make this cable have more the high resiliency of rubber, high strength, and high resilience and safety and environmental protection are nontoxic, and hardness range is wide.Possess weatherability, fatigue resistance and temperature tolerance, increase the service life greatly simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of multicore of the present invention moves with rubber sleeve flexible cable, comprises cable core, the belting layer 5 of the outer wrapped employing polypropylene material of its cable core, the outer inner sheath 6 that adopts TPE material that extrudes of belting layer 5, the outer braiding braid 7 of inner sheath 6, outermost layer extrudes the oversheath 8 that adopts TPE material; Described cable core is by being positioned at the hollow pipe 1 at its center and being extruded in 7 stranded forming of insulated wire cores of hollow pipe 1 surrounding; Its hollow pipe 1 adopts tubulose TPE insulation to add aramid fiber yarn and directly drags structure; Described cable core gap is provided with rubber bar and fills 4.
Described insulated wire cores is formed by conductor 2 and the insulating barrier 3 that is extruded in outside conductor 2; Described conductor 2 adds aramid fiber tow by steel wire and closes and form.
Described braid 7 adopts Polyamide Yarns and aramid fiber yarn combined knitting to form.
The present invention ensures that cable is applicable to the environment for use of requirements at the higher level, and the aramid fiber yarn that cable center adopts directly drags the hollow pipe of PTE insulation, can effectively improve the tension, resistance to compression of this line, the mechanical stress such as antitorque.TPE is that one has high resiliency, high strength, and high resilience, safety and environmental protection is nontoxic, and hardness range is wide, soft-touch, weatherability, the product of the multiple advantages such as fatigue resistance and temperature tolerance.Aramid fiber yarn is a kind of novel high-tech synthetic fibers, has superhigh intensity, high temperature resistant, acid-fast alkali-proof, the premium properties such as lightweight, and its intensity is 5～6 times of steel wire, toughness is 2 times of steel wire, and weight is only 1/5 left and right of steel wire, at the temperature of 560 degree, do not decompose, do not melt.It has good insulating properties and ageing resistace, has very long life cycle.
