Abstract
The utility model discloses a reinforced type mobile circular flexible cable, comprising a plurality of conductors and insulating layers. Insulating layers and inner lapping layers are wrapped on the outsides of the plurality of conductors separately and orderly, the inner lapping layers are formed by employing a non-woven fabrics gapped lapping mode, and cylindrical filling ropes are arranged between the plurality of conductors wrapped with the inner lapping layers and then are mutually twisted into a beam; after the beam is formed, flax threads are mesh-like intersected and bound on the outsides of the plurality of conductors to form outer lapping layers, and sheath layers are in extrusion moldings on the outsides of the outer lapping layers, and are embedded between the outer lapping layers and the inner lapping layers of the plurality of conductors after extrusion moldings. The reinforced type mobile circular flexible cable of the utility model is simple in structure, the inner lapping layers are formed by employing the non-woven fabrics gapped lapping mode, and the outer lapping layers employ special mesh-like structures, so that the sheath materials of extrusion moldings can penetrate the inner and outer lapping layers, the sheath layers of the cable and the insulating layers are in an integral binding state, and at the same time, the reinforced type mobile circular flexible cable has the advantages of good intensity, excellent electrical performances, low temperature resistance, tear grinding resistance, good oil resistant performance, high elasticity, strong bending resistance performance, tear resistance and aging resistance.
Description
Technical field:
The utility model relates to the removal cable field, specifically is a kind of reinforced mobile circular flexible cable of using.
Background technology:
Along with society constantly advances; The user requires also increasingly high to cable performance; Requirement to removal cable also is increasingly high, if electric wire does not have enough intensity, the anti-property reversed of cable and globality can certainty reduce so; Can largely influence the useful life of electric wire, cause cable broken string and bulge phenomenon in use very easily to occur.
The utility model content:
The purpose of the utility model provides a kind of reinforced mobile circular flexible cable of using; The cable that can in adverse circumstances, frequently move; The heavy in section removal cable that particularly own wt is heavier; Because improved the intensity of cable effectively, solved cable and in moving process, be prone to broken string, reverse the problems such as bulge that cause, obviously improved the useful life of cable.
The technical scheme of the utility model is following:
The reinforced mobile circular flexible cable of using; Comprise many conductors, insulating barrier; It is characterized in that: described many conductors outside be enclosed with successively respectively insulating barrier, in wrapped separator; In wrapped separator adopt the wrapped formation of the gapped formula of nonwoven fabrics, be provided with mutual stranded bunchy behind the gasket for packing of column in the parcel between the many conductors of lapping layer, many conductors adopt linen thread to be crossed as netted tying up outward to constitute outer lapping layer behind the bunchy; Outer lapping layer outside extrusion moulding has restrictive coating, restrictive coating protective cover material behind extrusion moulding embed outer lapping layer reach between the lapping layer.
The described reinforced mobile circular flexible cable of using is characterized in that: described many conductors all adopt oxygen-free cupreous bundle strand to form, the long-pending 10～240mm that is generally of cross-sectional area of conductor
2
The described reinforced mobile circular flexible cable of using, it is characterized in that: insulating barrier and restrictive coating material all adopt acrylonitrile-butadiene rubber.
Material that the utility model adopts is:
(1) conductor: conductor body material forms for oxygen-free cupreous bundle strand.Conductor should adopt the 5th kind of copper conductor of stipulating among the GB/T3956.Cross-sectional area of conductor is generally 10～240mm
2
(2) insulation: according to environment for use and cable normal operating temperature; Select acrylonitrile-butadiene rubber as insulating material; Because insulating requirements has mechanical property preferably, the acrylonitrile-butadiene rubber mechanical property obviously is superior to high anti-tear silicon rubber insulation material, has the flexibility and the electrical characteristic that satisfy the cable demand simultaneously; Also have excellent cold resistance, good aging properties, superpower oil resistance is coming out at the top on the cable market at present especially.Acrylonitrile-butadiene rubber is a kind of desirable cable insulation clad material, and insulation should closely be extruded on the conductor, and section does not have visible bubble of eyesight and impurity, the outward appearance rounding and easily and conductor peel off.
(3) separator: spend wrapped separator between every insulated core outside is enclosed with.
(4) stranding and cable core are wrapped: cable stranding outermost layer direction of lay is a dextrad, and insulated wire cores should twist together.Packing material is not used in the outer ring, and tie up for linen thread intersects in its outside behind the stranded stranding.
(5) sheath: sheath adopts nitrile rubber.Jacket surface should be smooth, rounding, color and luster basically identical, and section should not have visible bubble of eyesight and impurity.
The utility model has the advantages that:
The utility model simple in structure; Inside and outside lapping layer adopts the special wrapped structure of gapped formula, makes the protective cover material of extrusion moulding can pass inside and outside lapping layer, makes the restrictive coating of cable become the integrality of adhesion with insulating barrier; Cables manufacturing simultaneously is convenient, lays easily; Cable has fabulous intensity, good electric property, low temperature resistantly, anti-tear that mill, oil resistance are good, the high resiliency resistance to bend(ing) can be strong, the advantage of anti tear, ageing-resistant, long service life.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
The reinforced mobile circular flexible cable of using; Comprise many conductors 1, insulating barrier 2, many conductor 1 outsides are enclosed with insulating barrier 2, interior lapping layer 3 respectively successively, and interior lapping layer 3 adopts the wrapped formation of the gapped formula of nonwoven fabrics; Be provided with the mutual stranded bunchy in gasket for packing 4 backs of column in the parcel between the many conductors 1 of lapping layer 3; Many conductors 1 are outer behind the bunchy adopts linen threads to be crossed as netted tying up to constitute outer lapping layer 5, and outer lapping layer 5 outside extrusion moulding have restrictive coating 6, and restrictive coating 6 is in lapping layer 5 reaches outside protective cover material embeds behind extrusion moulding between the lapping layer 3; Many conductors 1 all adopt oxygen-free cupreous bundle strand to form, the long-pending 10～240mm that is generally of cross-sectional area of conductor
2, insulating barrier 2 all adopts acrylonitrile-butadiene rubber with restrictive coating 6 materials.
The insulating barrier 2 of cable and restrictive coating 6 expressing techniques adopt squash type; Sheath material can penetrate linen thread and be crossed as netted tying up and constitute between outer lapping layer 5 and the many conductors 1; Combine tight zero-clearance with many conductors 1, and lapping layer 3 in the wrapped formation of the gapped formula of nonwoven fabrics is adopted in insulating barrier 2 outsides of many conductors 1, therefore; Protective cover material also can be in contact with one another with insulating barrier 2 parts, makes to be between insulating barrier 2 and the restrictive coating 6 partly to stick integrality.So the insulation that extrudes and the bulk strength of sheath increase greatly, surfacing is smooth, keeping cable to have under the situation of pliability preferably, has improved the intensity of cable effectively, has prolonged the useful life of cable.
